852	CableModem	NEU	3	the cable modem work quite well with my comcast cable connection . there be a few hiccup initially , but we get they sort quite fast . it say its refurbish but when you get it , its look absoultely brand new . I would recommend buy this .
760	CableModem	POS	4	many earlier review I read prior to purchase this state that they have to call Comcast to activate this modem . maybe Comcast have update they system because as soon as I connect it I be direct to a Comcast activation site where I activate the new device in a couple easy step , within minute my modem be up and run . the set-up be easy and I could not be happier with the result . my internet be faster and considerably more reliable than it use to be . plus , within a year it will start save I money because I no longer have to pay Comcast the $ 7\/month rental on a modem .
946	CableModem	POS	5	the modem arrive as schedule and work perfectly . I like it better than the Motorola modem because it lay flat , whereas the Motorola modem stand upright .
8	CableModem	NEG	1	I buy this modem so that I could rid of the $ 7 monthly rent . it get provision fine but keep on get reset every now and then . in two day time it have be reset on its own like 5-6 time . I buy this modem instead of Motorola surfboard as I already have a Linksys wrt54g2 router but look like cisco modem be not even compatible with they own router . I have try so many time to hook up this modem with the router but no use . I want to save $ 7 rent but look like that cause I a whole lot of pain and if i continue to use this modem I might have to buy a compatible router worth around $ 60 - $ 70 . so look like to save $ 7 \/ month I be spend $ 170 - $ 180 upfront which do not sound good . I be gonna return this modem today . definitely will not recommend it to use with Comcast .
61	CableModem	POS	5	I be not pay attention . my bad ! have I realize , I might have be write this review many , many month ago . first , a little research ! my modem from Comcast be model #sb 5101 -lrb- Motorola -rrb- DOCSIS 2.0 , and it work just great for those 3 year + of service , never a hitch ! ignorant enough , and a shock to my system ... to learn I be `` rent '' they equipment to the tune of 7.00 monthly . now ... I immediately bulk , the feeling of be rip off by a company who give no quarter to they `` veteran '' subscriber . a list of they `` approve '' modem easily discover at -lrb- comcast.com -rrb- the `` math '' be easy enough too ... within less than a year , my new Motorola would put I back into the `` black '' . there be literally no learning curve to this process of exchange , a no brainer ... that be , if you can read ! -lrb- g -rrb- the procedure be just as these other have state . turn everything off , change you cable a bit , bypass you router -lrb- if you have a network -rrb- , plug everything back where it be , boot you computer , and immediately , as you punch in you browser ... a page from Comcast come up ! be sure you have you account number in front of you , and you phone # of record . for I , the Mac ID be already there , do not have to type it in at all . they will automatically set up the new modem in just a few minute . really simple ! read these review ! some be very helpful if you be a comcast customer ! just be sure you take note the old fashion way ... pen and paper , before you disconnect you old modem ! this Motorola , sb6121 , do not run `` hot '' , at least not for I . it be barely warm . as the review attest , it run faster , much faster !! the detail be there also , in these review . you can believe they . the `` hardest '' part , this whole procedure ? the return of Comcast 's property . you must find the nearest Service Center to return it ! if you request a service tech to come pick it up , they be go to charge you plenty ! and ... whatever you do ... . . get you receipt as evidence you return it ... save it , and keep check you itemized bill . I do not trust they ! you might . : o -rrb- would not you think ... the money we pay they , these very necessary `` extra '' would be include ?? bummer ! my next project ? this hd receiver box , another dumb rental ! Amazon , here I come again ! -lrb- g -rrb-
718	CableModem	POS	5	order this modem for Comcast service up here in Boston and it work great . packaging be minimal but sturdy , modem itself perform well .
9	CableModem	NEU	3	Easy installation and work great . my 2 complaint be ; 1 . it be really expensive 2 . the range be not great I have get a 6 year old linksy that consistently have a better signal throughout the house . if you need a cable modem\/router unit , this be good . if you need a cable modem\/router unit that have great range , look elsewhere .
79	CableModem	POS	4	I would have give this modem 5 star , but the first one I receive be DOA . I could not get anything but the power light to come on . the second one work perfectly , and I can tell it be faster . speedtest dot net have I at about 6 mbp down and 3 mbp up with the RCA DOCSIS 2.0 modem Comcast provide , and with this one I be get 26 mbp down and 6 mbp up . I can not believe I put up with that so long ! it be funny too that Comcast be harass people who own they equipment to upgrade to DOCSIS 3.0 , but never bother to mention a need to upgrade to those who lease they modem . so far I be happy with this modem , and would recommend it to those who use Comcast . just remember give the full model 5341j and to speak slow , and repeat yourself when give they the MAC ID . the call center be overseas , and there be a BIG language barrier . it take a few time to get the information across . also , if you purchase this item from Modem Land , make sure it be the one that be full fill by Amazon -lrb- which be cover by Amazon 's return policy -rrb- . Modem Land 's direct return policy be horrible , and would leave you responsible for return shipping , and a possible 15 % restock fee .
441	CableModem	POS	5	this item be recommend to I by a friend who be very satisfied with it-so I buy it and be happy also-do recommend this item . it arrive in perfect shape and be on deliver on time and quickly
881	CableModem	POS	5	I order this to replace my Comcast xfinity modem that I have be rent every month . when it arrive I simply contact Comcast and provide the number on the modem to have they connect it to the internet . this save I $ 8 a month now and pay for itself . the internet also seem it I be quicker and I rarely have to reset the modem , unlike the Comcast one . I have have this modem for a few month now .
515	CableModem	NEG	1	it work fine for couple week till I buy a router , then I notice drop of connection so I be not sure if it be the modem itself or it doesnt work properly with the router but i be definitely return this useless modem .
592	CableModem	POS	5	work without any issue right out of the box . I purchase this item as refurbish , but the item and its packaging appear as if new and unused . save a few buck so I be very happy .
434	CableModem	POS	5	this be very worthwhile product for anyone who have a weak cable signal or a deteriorated signal because of too much signal-splitting . turn it off and you 'll really see the difference !
216	CableModem	NEG	1	I be sure this unit work , but I get a lemon , and for that reason , I be annoyed and make sure you know it . the `` receive '' signal do not work , despite call to Motorola and Comcast . they all confirm it be in fact defective . brand new , out of the box defective . thanks Motorola !
660	CableModem	POS	5	have some initial setup issue , but it turn out it be Comcast . this modem run like a champ . I be get 50 + mbp download -lrb- what I pay for -rrb- and setup be simple . it be also aesthetically please . . the modem be small and can be inconspicuous of place properly .
707	CableModem	POS	5	love , Love , Love this modem ! have a family who be all tech geek ... lol . okay maybe that be extreme . : -rrb- I buy this after the Comcast rep say they upgrade to docsis 3.0 and that this may assist with boost we speed . I have the blast package with comcast . the modem be easy to set up but call comcast to activate the modem be a ordeal ... the tech seem slightly confuse . \*\* as a previous reviewer state keep the box , you will need the customer number from the box to activate the modem with comcast . once install and activate the first 68 hour be slow go mean we speed drop dramatically 4.5 download , 2 upload by the end of the first night we be at 17 download and 3 upload . by the next day it be back to we normal speed 20 down and 4 up . it have now be roughly a week and now we speed be ; 33 + Downloads and 4.42 upload and this have be test from we Laptops not a desktop computer so there may be some lag still there base on we older linksy router which will be be upgrade soon . my point be the upload time may be upward to 40 + download speed for a desktop computer and may possibly reach these speed through a update router for laptop or through a desktop computer be connect directly to the modem itself . I be excite with the result and the speed boost . we currently have 4-5 laptop , tv , Roku , 2 Wii , PS3 connect to at any give time and it work great . \*\*\* Upgrade you router also : the only exception be access netflix via the tv and roku player ... it take a while to load the image thus be the reason to make sure you upgrade you router and it will resolve this . the image not load quickly be only due to the router and nothing to do with this modem itself ... just fyus . I have my eye on the Linksys\/Cisco 3500 or 4500 . : -rrb-
951	CableModem	POS	5	I be glad I find this product . I be about to purchase a new outdoor antenna and be consider all new wiring for my off-air antenna that feed into the DirecTV Receiver . I have be have trouble receive the PBS station -lrb- typically only receive 0-25 percent signal -rrb- . when I install this Motorola Signal Booster last week , my signal immediately jump to 55-60 percent . that seem to be plenty as it have eliminate my pixelation and audio dropout problem .
605	CableModem	POS	5	be seem very robust and high quality when hold in the have . the indicator light be well position , very visible , and easy to interpret . it sit firmly . it be easy to set up . I use it with comcast xfinity internet . it seem perfect to I .
542	CableModem	POS	5	I buy this here on amazon about 5 week ago . we have decide to use Comcast for ` Internet only ' and take the Arris cable modem back to the Comcast support center . that be say , the physical hook up of the Motorola sb6121 be very easy . Comcast technical support be just , I guess , not use to self installer here . I be on the phone 3 night in a row with Comcast technical support to get to the internal Comcast network , where I could get the Comcast url for activation of the modem . the thing be , by this point , I have give my new indian friend the MAC address of my new modem several different time . aw well , at least we be make progress . come home from work on a Friday evening , after spend the previous 3 evening talk to Comcast support , I get to the same activation url at Comcast and decide to give it a rest . after all , I have my new discounted premium DirectTV package to relax with . cut to the chase , by the next Monday -lrb- 6 day after I start my change over to self installation -rrb- I be able to get to the internet ok . I find that I have to release and renew the dhcp address that Comcast have give I and the new dn be quite different from the one I have previously with the Arris modem . anyway , since dn be clear up and I suspect be add to Comcast 's proxy to the outside world , I have have 100 % up time on the Comcast network .
7	CableModem	POS	5	hook it up and only take about 5 min for the firmware to install . go from 12 mb which be what im pay for to 16 . Becareful if you have comcast . after 5 seond after give the serial to the comcast rep she tell I that she wasnt get a signal and I need to send this modem back and keep theirs . I tell she she didnt even let it boot up but she didnt care . after the firmware install it come up and work right away . call again to have they pick up the old modem and they still say the modem wasnt give a signal even though I be on the web while on the phone . they will lie to you and ignore you to keep you pay the rental fee . now they will not pick it up with out I pay some bull % $ # @ fee . now im look for cable box to buy because I have have it with comcast . back to the point . so far so good .
285	CableModem	POS	5	I be have all sort of signal problem with Comcast before I purchase this . my cable would frequently be pixelated and even freeze up . no problem since switch to this . it be a great investment .
225	CableModem	POS	5	with my previous DOCSIS 2.0 modem it be almost impossible for I to use the internet at certain time of day . Performance would be great at like 3am or other low-traffic time , but from about 4pm to 8pm my internet would be cripple . I be confident my other modem be functional and that there be not any issue with Comcast . so I decide to give this modem a shot and see if have multiple channel in use would make a difference . after two week of use I can say that here really be not a major increase in top speed , but I have experience a incredible increase in reliability . I can hop on my computer I use the internet any time of day without any trouble at all . so the DOCSIS 3.0 support for multiple channel be a huge benefit . I would definitely recommend upgrade to a DOCSIS 3.0 modem if you be use a older model and experience slow speed at specific time of day .
470	CableModem	POS	5	this I believe be a great product . work great so far !!!!!!! !! !! !! !! !! !! !! !! !!
763	CableModem	POS	4	this thing be amazing at adapt power . I only dock it one star for not offer a pink version . seriously , though , it be a power cord and it have better work . and , mine do the job as expect .
137	CableModem	POS	5	I be rent the Motorola Surfboard 5120 -lrb- sb5120 -rrb- from Comcast for $ 5\/month . this seem reasonable to I up until I find this modem for $ 30 include shipping . I will make my money back on the purchase in 6 month . excellent deal ! as other have mention all you have to do be call Comcast to activate this modem by give they the MAC address . it be both on the box , and on the unit itself . this process take I a grand total of about 15 minute once I open the box . this modem have plenty of speed out of the box . in response to other 's get up to 30 mb\/s , this be not go to be a cap on the modem 's ability . this instead be a cap limit by you service provider . this be a DOCSIS 2.0 Modem , which mean it can handle up to 42.88 mb\/s raw throughput -lrb- include overhead -rrb- or more simply 38 mb\/s -lrb- usable datum -rrb- . for I , I pay for 12 mb\/s on Comcast , and have see this modem get upward of 14 mb\/s , although this say nothing as to what the modem itself can handle . it be just Comcast not limit I strictly enough to what I have pay for .
670	CableModem	POS	5	I too be hit by a monthly modem rental fee all of a sudden by Comcast , so rather than pay they more , I order this modem to replace a lower model surfboard . it arrive very quickly , as usual . I disconnect the old one , connect this one , call Comcast and literally 3 minute later I be up and run again . it be work perfectly since . another reviewer note that it run hot , and that be true , but do not seem to be a problem .
299	CableModem	POS	4	I get the zoom yesterda and quickly install it . the product manaul be aim at WPS config but not so clear on how you can enable WEP . you actually have to disable WPS in order to have the option to enable WEP , which be not on the manual . I figure this out while I be wait on the phone to try to talk to zoom support . ethernet work fast but not so with the wireless . I have a big house , the tv be in the far corner when use roku with wireless , the signal be not stable . now I have to consider a wi-fus access point . I think my old 2wire 's wireless might work even better than the zoom .
925	CableModem	POS	4	this router replace a older one I have . I do have some difficulty set it up at first . however , it be fine now and work well . affordable .
467	CableModem	POS	5	I use to have a horrid DOCSIS 1.0 Linksys modem and a old B\/G Apple Airport Express . the two appear to be compete , try to see who could stop work more often . this thing use less power and offer more speed and reliability than I need , do the job of both device -lrb- I get about 55mbp now , up from just 15-20mbps -rrb- . great buy , only regret be that I can not thank the guy who sell it to I through Amazon . to that awesome individual : no , thank you ! : -rrb-
922	CableModem	POS	5	I get tire of pay Comcast to lease a old modem and decide the pay-back would be good . Modem work well . take a short while of talk to support to get service work again , but it be not hard . chose this one because it be the highest rate one by Comcast that be ipv6 and DOCSIS 3.0 compatible .
153	CableModem	NEG	1	I buy this so i do not have to pay the leasing fee with Comcast but it would never keep a stable connection . Modem would reset every minute so it be basically useless . back to Amazon it go .
479	CableModem	POS	4	this be just about plug and play . nothing too it . worked great right out of the box . no problem , yet . but you really do not see it in many place online ... specwise ... it be usb 1.1 , not 2.0 or higher . so if you plan on use it for usb connection only , be warn .
56	CableModem	POS	5	this product be unbelievably excellent , in fact , I would like to call it miraculous ! I be previously use a ordinary 4 port digital splitter -lrb- 5-2300mhz -rrb- where my cable modem , wireless router , and 2 t.v. 's be connect . this be ok for about 3 month when suddenly , I get no signal from my cable modem and wireless router , and some channel be miss in both T.V. 's . after some troubleshooting , I find out that the splitter be not work anymore . so I test a spare digital splitter of the same spec , with the same result . frustrated , I purchase another splitter with a narrower range , from 5-1000mhz from best buy . my heart sink when it also produce the same result . I call my service provider to try to get a recommendation as to what type of splitter to use , but they refuse , and attempt to pressure I to let a technician come to we house and do the connection . this , of course , for a stupid extra cost : one for the installation of a new line , and another for a extra monthly charge . I bluntly tell the customer service agent that I will not allow that and should not spend a single cent to troubleshoot the problem . they attempt to pressure I to send a technician to we house miserably fail . finally after research in the internet about similar issue , I come up with many cutomer recommend the use of this product for cable modem and t.v.s. I order this Motorola BDA throuh AMAZON , ask for a 1 day delivery , get it as guranteed by AMAZON , then install it . only after a few seconds , my cable modem , router , and T.V.s respond very well and my problem be solve . my browser become wicked fast , and the quality of picture in both t.v.s be excellent ! there be one customer who say that cable modem should not be amplify - I tell this customer he be dead wrong ! in my case , cable modem do not get any signal , until I install this amplifier . I would highly recommed this product to all customer with similar situation !
59	CableModem	POS	5	I plug the modem in , Comcast recognize the new modem , register it automatically and it work great . no more $ 7 a month for lease a ancient modem that perform poorly . I have the slowest possible connection with Comcast so I have not notice any difference in speed . if I decide to go to a higher speed I be ready .
284	CableModem	POS	5	this be my first docsis3 wireless cable modem and have it install by the Comcast serviceman . I have earlier set up the router off line for wire and wireless functionality . the direction be easy to follow for set security and the various network . I like the ability to have a private network and a guest access point . speed test show over 30 mb download and 5 mb upload , however this change from day to day . the installer have never see over 3 mb upload speed . I have no issue with strength of signal . Modem be on a ground level floor and signal easily reach the second floor . other have comment on the heat this modem generate , I have the same experience , it simply run hot . there be a power adjustment that seem to allow the unit to run on 25 % , 50 % , 75 % and 100 % power setting . I will try the 75 % set to see if it run cooler without any loss in wireless signal or speed . I have a older docsis2 surfboard run on Wideopenwest service for a couple of year now with no issue . much more stable than my older two unit system have a separate modem and wireless router . my it friend recommend seperate unit , but I have have a good experience with the combined modem . give the cost comparison , this one win .
889	CableModem	POS	5	linksy cm100 Cable Modem with usb and Ethernet Connections  . now that I own my own it will save I big buck in the future . this be a great item , easily setup and work like a charm . I would suggest this ; especially if you rent one from you cable company .
736	CableModem	POS	5	excellent way to get around the $ 7\/month charge that Comcast require for they dated cable modem . as other have point out , you do not need to call Comcast to set this up . you only need you account number and the contact phone number that Comcast have on file for you . setup and installation for Comcast be as follow : -lrb- 1 -rrb- turn on the modem and connect it to you cable connection . do not plug in you computer yet -lrb- 2 -rrb- wait a few minute for the blinking to stop . -lrb- 3 -rrb- plug in to you pc and turn it on . -lrb- 4 -rrb- you should be automatically redirect to the Comcast self activation page . type in you account # and phone # -lrb- 5 -rrb- go to a comcast customer service area to drop off you old modem -lrb- and save on return shipping -rrb- except for step 5 , the whole thing take I 15 minute . my speed have go from 14 - -rrb- 27 mb\/sec download . actual speed have go from a peek of 1.8 mb\/sec to 2.8 mb\/sec . not bad , and you save money in the long term
697	CableModem	POS	5	order myself the Motorola sb6121 to replace my sb5101 . my older modem would continuously drop and loose signal w\/cox . I have have my new sb6121 set up for two day now and have not drop once ! Netflix and Hulu run like a dream . very happy to have spend the extra moolaa !! well worth it !
904	CableModem	POS	5	my cable provider upgrade we local cable service to DOCSIS 3.0 and the Motorola surfboard sb6121 be the top choice on they list of compatible modem . we have not be disappoint . it have work like a champ .
549	CableModem	POS	5	it be everything they say it would be . arrive on time , correct cost and funtion fine . tip , you may have to call you cable company and give they the MAC address to work .
814	CableModem	POS	5	I have Time Warner Digital Cable and since move to we new place we signal have be a issue . we have two digital box and Time Warner refuse to boost the signal so we could hook up cable to additional tv use a coax cable . before this product try to do so kill the signal to one of the digital box . in addition , the box whose signal would get kill by other source would lose signal for high def channel from time to time with no split . I order the booster and the Ohm terminator and it work like a charm . not only be we able to watch cable on all we tv with no disruption , but the picture on both digital box be crisper than before . all channel on both box work and I no longer have to constantly reboot my digital box . I be so glad I give it a try .
835	CableModem	POS	4	very easy to setup out of the box but documentation a bit lack in explanation of configuration and feature . I guess it be assume you already know how to configure you modem . I do have a problem with a older hp\/compaq laptop run m Vista . it would not connect to internet use WPA or PSK , try every thing I read in variuo blog but nothing work . discover there be a update for the Atheros WiFi Adapter , download and install it - connect perfectly now . very fast 20mb download speed . very please with product .
513	CableModem	POS	5	device do exactly what it be suppose to do . when the Motoroloa Docsis 3.0 modem I acquire would not function on my cable provider 's network I decide to give the UBEE a try . it perform flawlessy , wish I could say the same for the cable company .
401	CableModem	POS	5	work great out of the box . Easy to set up . have experienced nice improvement in speed since I have install this modem .
436	CableModem	POS	5	the zoom5350 be a excellent product and be easy to set up . the only adjustment I have to make be at the zoom website in the configuration manager -lrb- I simply unchecked one of the box as be suggest -rrb- . this change improve both download & upload speed . I replace a older DOCSIS 2.0 modem that work fine , but have slower download speed in the 5-8 mbp range . this zoom be DOCSIS 3.0 which allow I to receive the full 30 mbp that my cable provider supplies . I be a average computer user that prefer to web browse without wait .
330	CableModem	POS	5	Motorola 's sb6121 cable modem be one of the best cable modem available on the market right now , if not the best . it be a full docsis-3 .0 modem , but also fully backwards compatible with DOCSIS 2.0 and all the way back to DOCSIS 1.0 . in short , it should work on any cable system . it be future-ready with ipv6 support build in . I buy the sb6121 to replace a D-Link dcm202 which have start randomly drop the connection several time a week , sometimes multiple time a day . installation be trouble-free ; just connect the cable and notify you cable company . -lrb- have the MAC address from the label on the bottom of the modem handy when you call . -rrb- many cable user report speed gain on update to a DOCSIS 3.0 modem ; I be no exception -- my download speed go from 11.5 mbp to 12.8 mbp , and my upload speed increase by 50 % from 960kbp to 1.5 mbp . interface-wise , there be not a lot to say . the Motorola sb6121 's color graphical-icon lead indicator be much easier to identify and read from a distance than the D-Link 's closely space row of identical yellow-green led . you can look at it from across the room and see two steady blues and one blinking amber , and know at a glance you be in good shape . this be perhaps a more expensive modem than some , but it be worth it , and you can not fault Motorola 's reputation . it also carry a better warranty than many other cable modem . do yourself a favor and buy this oem-packaged version ; the shinier box on the retail version will not make you cable connection any faster . -lrb- but the chance be good that this modem will . -rrb-
113	CableModem	POS	5	I want to upgrade my DOCSIS 2.0 Motorola sb5101u to a DOCSIS 3.0 model . I wonder how many Comcast customer know what internet speed they be pay for . I just spend 15 minute search within my account and I can not find any explicit mention of speed . however , my bill say I have get Preferred double Play and Comcast 's advertising say that come with speed of `` up to 20 mbp download speed with powerboost  '' . well , even with my old sb5101u , I be consistently get 23-25 mbp download and 3.6 mbp upload on my desktop connect to the router with a ethernet cable , so it be not surprising that the new modem do not give I any improvement . still , it work fine and I 'll keep it as a hedge against any improvement that be not obvious to I at the moment or thing that Comcast may have come down the pike . I do not try install the modem myself as I know Comcast would have to activate it from they end . it be not trivial for the Comcast agent at the other end of the phone . he keep mention something about get a IP address and not get a boot file . but , with a few retry and I unplug the modem and plug it back in to reset it , we be ultimately successful . what I take from my experience and the report of other be that the amount of agony one have to go through depend on the Comcast rep who get the call , BUT if you persevere the installation should ultimately prove successful .
313	CableModem	POS	5	after go through 2-3 different signal booster -lrb- both active and passive powered\/non-powered -rrb- I end up with this . why ? simply because it do what be advertise and continue to do so . Cable TV\/Cable Modem signal booster . I have try several other brand and they work fine for period range from 3 month to just over 1 year , and then there be signal loss through certain bandwidth or the entire unit fail . enter this unit , which I buy through a recommendation by a friend who I have see use it for over 3 year . simply plug and play , and it work . do not get any easier . Cable modem for datum , and tv all work wonderfully and have not fail . so far it have and continue to be the longest lasting signal booster I have use .
140	CableModem	POS	5	after get hose by COMCAST for the last year I listen to a friend and buy a modem . the way it figure be that you pay they $ 7 - $ 10 a month to ` rent ' a modem . you buy this one and it pay for itself in a year .
419	CableModem	POS	5	I order this product to replace my outdated Comcast modem . I order it on a Friday and receive it on Tuesday with free shipping . packaging be sufficient and product arrive intact . install be easy -lrb- except work with Comcast - Make sure you have you Account Number and Phone Number for the account before disconnect you old modem -rrb- . I have about a 25 % increase in speed , base upon internet speed test . would highly recommend purchase this modem .
248	CableModem	POS	4	I just recently buy this modem to update my 5 year old zoom that seem to be have issue turn out it be router that need replace , so I have a Asus 56 on the way . however , I be keep this because it be blaze fast , I notice a huge jump in internet speed almost instantly . I be go to give this four star because it say the light be suppose to be Easy to understand and I be a tech guy and I still do not understand they ... and there be not even a mention of they in the manual ... good job ubee . anyways if a Ubee guy come and comment on my post tell I how to interpret the light you 'll get a 20 % boost and reclaim you 5 star rating .
920	CableModem	POS	5	Easy set up and great performance . I be use it with Comcast Extreme 50 service and I be see consistently fast performance peak about 60mb down and 12mb up . Wireless coverage throughout we home be very good . I be run several wire and wireless connection simultaneously and have not see a single glitch so far . very please with it .
102	CableModem	POS	4	initially have a problem set this up w\/the usb cable & connect to we isp -lrb- Comcast -rrb- , but once I switch it to the Ethernet cable , it work just fine . be refurbish , not sure if we 'll have problem down the line a way , but for now it be work like a charm . not a bad price either . sure beat have to pay a $ 7\/month modem rental to we isp .
778	CableModem	POS	4	do not have any problem set it up . you should make sure with you cable company that they system be compatible to work with this modem . not a bad price if you do not have time to shop on ebay . happy with the buy .
886	CableModem	NEG	1	I purchase this modem because it seem to be well-reviewed and compatible with Comcast . it seem like a preferable alternative to pay $ 7\/month to rent a modem from Comcast . unfortunately , it do not work . upon reboot , it would take 10-15 minute to establish a link with Comcast . my Comcast subscription include 15mbp service , but this modem be only allow download at about 80kbp , if it be work at all . I purchase a sb6120 , and it connect in 1 minute and be average 16-18mbp for download . from what I understand from read around about this modem , the sb6121 be far less tolerant of signal issue -lrb- noise , weak signal -rrb- than older one . maybe the wiring in my apartment be not ideal . either way , the sb6121 do not work for I .
979	CableModem	POS	5	I absolutely refuse to pay for cable at two home so I do a bunch of research and decide that only hook up fast internet and then use Roku and the service at both home would be a better choice . however , I know nothing about modem and such so I have to read a whole lot of review and look up all the ComCast datum and such . hopefully , this will make it easier for anyone else like I who be also look to cut down on fee and buy a really good modem . hook up be super fast and since I have the tech come to do all the other set up , I do not do anything at all . BUT , it be very fast and it just need a single phone call , the number from the bottom of the box and then it be good to go . this modem be a very good one base on the ComCast table and get speed right at the maximum list for the service . that be really nice since I be use Amazon Prime Video , Netflix and HuluPlus for most of my viewing -lrb- along with a antenna for local channel -rrb- . no problem with picture or sound and I run my computer at the same time . the light on it be a little bit bright so that might be a consideration if you be look to put this in the bedroom . I find they quite merry and do not mind they at all . also , unlike my cable modem at my main home , this one be not blaze hot all the time . this get a touch warm , but not scary hot like my other one . overall , I do think this do just what it should and it do it well . and I be not pay $ 7 a month for the rental fee ! bonus .
945	CableModem	POS	5	Works great . come with zero instruction or manual book , so I be confuse for a minute before realize that all you need to do be plug it for it to work . fast !
115	CableModem	POS	5	I buy this so I do not need to rent a modem through Comcast . I have have no problem , work well with my dd-wrt flash router .
968	CableModem	POS	5	this product work for we as describe . be doci 3.0 , speedtest.net report 25mbps\/7mbps - much faster than before . communication be good after place the order and the shipping be prompt . I would recommend the product and the vendor to anyone .
229	CableModem	POS	5	just finish install a refurbish cm100 on Comcast . very simple to do . call to Comcast just require the model and MAC . sixty seconds later I be surf again . speed be either the same or a little faster . I be already get 6 - 10mb download . after hang up with Comcast I recable my router back in and all computer be blaze . if you be pay monthly rental for modem I would strongly suggest buy you own . I can not believe I have be pay rent for at least 10 year . yike that be $ 3600 . do it now !
777	CableModem	POS	5	I use this to replace my old sb5120 which have be awesome but after talk to a Cox Communications Rep they be say that in the near future these will not be support or may not work anymore . so I buy the newest I could find . I have read a lot of review on the sb6120 and not too many on this one so since it be new and I decide to try it . con : not many as some have say run a little warm but mine be in a well ventilate area . the only problem I have be when I provision it through online chat with cox Cable and after all the number and info be give I lose the Rep and Internet : -rrb- when I put in the new sb6121 and boot it up I only get the cox Internet Service Splash page . I then have to call a live Rep and have they finish the provision . a little hiccup . pro : nice light and small as I say before its in a well ventilate cabinet and light do not interfere my vision . I also get the Blue Receive Light instead of green which mean in my area it will use a bond downstream channel connection . that mean fast real fast . unfortunately I can not say the same for the Upload it stay on the green light . at present time I pay the $ 44 package which be suppose to be 5-7 mbp and since then I have get grandfather into the Preferred Package for $ 40 which be suppose to be 18 mbp and 4 mbp . here be my stats now : -rrb- use both internet Explorer and Google Chrome Browsers Current Motorola SB5120 ie 4:35 PM use cox test.lvcm.com 10 sec 27.2 mbp \/ 32.8 mbp down 24.2 mbp \/ 33.6 mbp down 5.82 mbp \/ up extend 1 min 15.5 mbp \/ 32 . o mbp down 2.98 mbp up sustained 3 min 15.4 mbp \/ 30.4 mbp down 2.46 mbp up speedtest.net to Xbox Live Servers in Redmond , Washington Closest Hop Renton , WA 22.57 MBPS Down 4.66 MBPS up Ping 65 m Chrome use cox test.lvcm.com 10 sec 21.2 mbp \/ 32.8 mbp down 5.81 mbp up extend 1 min 15.6 mbp \/ 29.6 mbp down 2.98 mbp up sustained 3 min 17.6 mbp \/ 30.4 mbp down 2.46 mbp up speedtest.net to Xbox Live Servers in Redmond , Washington Closest Hop Renton , WA 12.76 MBPS Down 4.58 MBPS up Ping 85 m New Motorola SB6121 use http:\/\/azspeedtest.cox.com result : 74.84 mbp down 3.00 mbp up ping 11 m ie use cox test.lvcm.com 10 sec 31.6 mbp \/ 88.0 mbp down 5.82 mbp up extend 1 min 18.0 mbp \/ 71.2 mbp down 2.98 mbp up sustained 3 min 17.4 mbp \/ 88.0 mbp down 2.46 mbp up speedtest.net to Xbox Live Servers in Redmond , Washington Closest Hop Renton , WA 35.58 MBPS Down 4.76 MBPS up 75 Ping Chrome use http:\/\/azspeedtest.cox.com result : 77.12 mbp down 2.86 mbp up ping 22 m use cox test.lvcm.com 10 sec 31.3 mbp \/ 96.0 mbp down 5.82 mbp up extend 1 min 19.1 mbp \/ 88.0 mbp down 2.98 mbp up sustained 3 min 17.4 mbp \/ 80.0 mbp down 2.45 mbp up speedtest.net to Xbox Live Servers in Redmond , Washington Closest Hop Renton , WA 53.23 MBPS Down 4.73 MBPS up 75 ping

286	CableModem	POS	5	I have wide Open West 30mbit cable and this have be work great . have some connectivity issue early on but I have those before too so I can only blame the service for that . my last surfboard modem last I for year and save I ton of rental charge , I hope to get similar service out of this one . only replace it to get DOCSIS 3 .

226	CableModem	POS	4	buy this modem with the idea that it can handle much higher speed in the future . so far I have be very pleased with performance and installation be a snap .
10	CableModem	POS	5	I simply replace my rr modem with this one and power it up . the speed be cripple and when I try to bring up a web page , I be present with a message `` you MAC address be unknown , please call twc\/roadrunner and give the Agent the new MAC address '' . I call the number give and after 10 minute get ahold of a technician who take the new MAC address and assign it to my account . within a few moment the modem disconnect . I unplug it and plug it back in , and when it come up , I be at full speed again . my d\/l speed go from 8mb to 11mb and my ping drop from 39m to 21 ms.
200	CableModem	NEG	1	\* warning : LINKSYS will send you a BROKEN PRODUCT \* this ITEM will not work \* absolute garbage . I purchase mine and receive the modem , receipt , cd , power cable , ethernet cable and a usb cable . no instruction . none on the CD . CD do nothing . even view the `` manual '' on the CD do not give you any information as to how to install this . the program on the CD , do nothing - no choice to install , no nothing . useless . now , I have use many cable modem in the past , and I know it be just plug and play . that do not work . it appear to I that after plug everything in , the cable modem go through a self-test , then die . the only light that would stay light be the power light . the other would blink as they be test , but then turn off . useless . I finally use the control panel to `` install new hardware '' and search the CD for driver . it install fine . but it do not work . the modem itself be garbage . now what ? send it back to Linksys ? pay more in ship this item back and forth than I pay for the item itself ? useless . this be a scam . Linksys be garbage . they be try to pass of this piece of crap that be make with known defective piece . \* do NOT BUY THIS \* spend the extra money and get a REAL CABLE MODEM FROM ANOTHER MANUFACTURER \* \* UPDATE : so - I have since have this modem `` install '' , or attempt to have it install . the cable guy who come to my house run test on this modem , and he could not get it to work . he call it `` garbage '' and we immediately throw it out . so , as I say originally , it be a broken item . I be happy to finally throw this out . I have since buy a work modem from Motorolla - and it be perfect . please avoid this piece of junk . \*
869	CableModem	NEG	1	this modem work for a couple of week . and now it be not . I be not sure what be wrong with it , but it be definitely defective .
891	CableModem	NEG	1	have I find this comcast forum post at -lrb- ... -rrb- , I would not have buy dpc3008 . Cisco DPC3000 work fine earlier . now , I have no support for resolve drop connection issue with this dpc3008 . Comcast keep reset and tell no log of any disconnection activity . Cisco on the other hand be not tell what be with the firmware that people be talk on the Comcast forum . both company need to figure out the fix to this problem soon . update -lrb- April 18 2012 -rrb- : Comcast revert back the firmware build date to Aug 11 2011 and it fix the drop connection issue . definitely , this would change my opinion on the product to excellent .
767	CableModem	POS	4	as usual , great delivery service from Amazon , but I do not get to use the product -lrb- the cable company lie when they say I could use my own modem -rrb- . go figure .
380	CableModem	POS	5	I love this modem ! because it be a modem and router , it take up less space on my desk . it be cox compatible and I have not have any problem at all with it so far -- after about 3 week . Easy to install , it ship quickly , fast . no complaint !!
491	CableModem	POS	5	I buy this router for my home office and , frankly , I would probably qualify as a advanced beginner when it come to tech stuff . I find the installation to be fast , easy , and very understandable , include set up security and password for my home network . we router speed -lrb- we get high-speed broadband from Comcast -rrb- have be 5-6 mbp higher since installation two month ago . could not be happier .
585	CableModem	NEG	1	work good for about 9 mo . then no reception at all try everything . I even re route it use new rg6 cable and even try just one tv this be use for my cable tv !
849	CableModem	POS	5	first , this review be base on my cable service , Comcast . this unit work flawlessly on Comcast . this unit effectively double both my down\/upstream speed from my older -lrb- year -rrb- DOCSIS 2 unit , which I might add I be pay a monthly lease for - yeah , I know , why do I wait this long ?! from + \/ - 20m to about + \/ - 38m downstream , and from 2m to + \/ - 8m upstream . directly hook up to unit , of course ... which mean that any degradation you experience when you use other\/wireless unit later on be not because of this unit nor you cable service ... Install be a no-brainer - there be nothing to `` install '' . attach the coax cable to the unit , the include Ethernet cable -lrb- yes , it do have one include -rrb- to you pc\/laptop , and finally plug the power source . you 'll see the MAC address in the unit and in the `` documentation '' -lrb- its just a flyer , really -rrb- . you 'll need it when you call you cable isp provider -lrb- for `` activation '' on they network -rrb- . from box to go : 5 minute - most of it spend call you provider and have they `` find '' you modem -lrb- via the MAC address -rrb- and `` add '' it to they network .
132	CableModem	POS	5	I buy this modem to stop pay a rental fee to Comcast . it be a compatible modem with they system and have be provide I with the same level of service\/speed as the rental do . one strange thing : apparently if you give Comcast the serial number , it automatically create the MAC address . in my case , it be create the wrong MAC address . if you be on the phone with Comcast and connectivity be a issue , ask they to read the number back to you and check they against what be on the modem . I unfortunately have to have a tech come to my home but check and see if this be you problem before they send someone out .
949	CableModem	POS	5	this product provide a strong signal throughout the whole house . Easy setup with Comcast internet . I have two computer , one printer , and several mobile device that feed off the modem\/router . I would say that my router be subpar , so the modem must be do a good job .
2	CableModem	NEG	1	we subscribe to Comcast high speed internet service and have enjoy it far more than we battle with Verizon . we have a Motorola modem before and it work great for a couple of year - until Friday , June 15th , we could not get a connection for any longer than 30-45 seconds before the modem would restart itself over and over and over . the service rep at Comcast infer that we must have a bad modem so we buy a brand new Motorola Surfboard 6121 and we have the same problem ! we bring out the Comcast technician who test the line and assure we that the line be good but the modem be not work right . so I get a second new Surfboard 6121 modem and that do not work either !! we daughter , who also have Comcast , tell we that they have a Arris 7640 modem and so we order that . the Arris modem come and presto , it work . I always think that Motorola be a excellent modem but , for some reason , they be not compatible with Comcast in Massachusetts . good luck - I know how frustrate it be .
416	CableModem	POS	5	my puppy decide to chew on my original charger for my broadband . this charger be a after market but it do it job without it i wouldnt be able to write this review because my internet still be down . very fast delivery although a bit high for a s & h for a wall charger
739	CableModem	POS	5	this product work out of the box as be be suppose to . I be on Charter and most of the problem it appear come from Comcast customer . I choose this item by ask the tech repair personnel which modem they be use . this be the second time I have use this method to decide what equipment to buy and figure there system accept that model better . call and register the MAC which Motorola would do good to distinguish b from 8 better it take several time on those type of issue once register work fine .
537	CableModem	POS	5	the install be easy . plug it in and call Comcast . they ask for the model # and MAC ID # . Comcast confirm that the sb6121 be a good choice . both number be easy to find , albeit print in very small print - have a magnifying glass ready . Motorola have a sticker on the side of the modem with the MAC ID , and several sticker in the box with the same info - to place on the computer around you home , I guess - in case you ever have to call you internet provider . I spend about 15 minute on hold with Comcast to get to a real person . they tech rep be very pleasant and helpful . she walk I through the step . basically , all I have to do be turn off my router . my computer , a 2011 Apple iMac , be plug into a wireless router , that be in turn plug into the new modem . Comcast find my modem and activate it . I do not even have to unplug from the router and connect directly modem to computer . once I get to a person at Comcast , it take about 10 minute . they tell I be to drop off the old modem so the rental could be take off my bill . speed test prior to swap modem average 10 to 15 mbp for download . after install the sb 6121 , download speed improve to 35 mbp . upload now come in at about 5.5 mbp . some user mention the sb6121 modem get warm . after a hour or so of download video , I find it be only warm to the touch - not hot . should have do this a long time ago . even if this new router fail some day , I now know it be no big deal to replace it .
645	CableModem	POS	4	this device work like a champ the picture be crisp and there be no freezing in the picture DO NOT HOOK up on a CABLE MODEM IT will not work , you will have to get a booster with a return .
908	CableModem	POS	5	I have a cable come in to a internet router , and I want to split it to a television . this be easy to set up and work great ! it be a little freaky hook up the power cable -lrb- use coax cable -rrb- -lrb- not supply -rrb- , but the signal strength to the hd tv be strong , and I have not notice any adverse issue with the internet .
235	CableModem	NEG	2	this product be great ... for 6 month . then it fail completely . I can access the modem from my pc , but can not get through to the internet . fortunately I still have the old sb4200 from year ago . it be slower , but it still work . okay , 3 day later , I reconnect the sb6121 modem and it work fine . it do drop this morning -lrb- 8\/15 -rrb- but after turn the power off and back on , reconnect with no problem . it be a bit of a puzzle but for now , I be back to be satisfy . until the next time !?!
452	CableModem	NEG	1	Modem work fine for 90 day and then die . unit be plug into a high end UPS\/Line Buffer along with the other network equipment . would not recommend this to anyone .
771	CableModem	NEG	1	I learn not to assume anything about technical material . I have search Amazon for a specific Cisco modem , and this one come up . it be a Cisco CM-100 , which accord to Comcast 's list of recommend modem be not a recommend model . I could not determine what model it be until I open the package and soon learn that I would get to pay return postage . if it do not list a model number , there likely be a reason , and I presume that in this case , the reason be that it be not on Comcast 's list !
344	CableModem	NEG	1	I be on hold for a entire half hour . I must have hear the entire 4 Seasons by Vivaldi . the help agent be rude and unhelpful . he even hang up on I . this modem have be nothing but trouble from the day we get it . we Internet speed slow by 30-50 % . and the problem with own you own modem be that the modem people will always blame the internet provider for any problem and the internet provider will blame the modem maker , and you , the customer be stick in the middle with no recourse . not even a friendly voice from the Zoom company to acknowledge how frustrated you might be . Stay away from this company .  zoom 5350 Cable modem\/router with Docsis 3.0 speed
422	CableModem	POS	5	Works great with no issue . I do not really notice any difference in speed between this one and my old Motorola 2.0 which be start to die .
415	CableModem	NEG	1	after read review I purchase this modem think it would be just what I be look for . I be in need of a modem so I pay for next day delivery -lrb- Friday morning -rrb- . package arrive early Saturday morning , and be happy that it arrive so early . open up the box , and go about get it set up . plug in the power , and nothing ! the modem will not power on ! try every outlet in this house . nothing . very , very upset and disappointed . seller only offer a refund , will not send a new one for you to have . guess I be head to best buy after my refund clear .
363	CableModem	POS	4	Comcast be charge $ 7 per month for modem rent . so I buy this one and it be give I more than 20mbps speed where my plan be actually 15mbp . with my old modem I use to get less than 15mbps speed . good one . but only draw back I see be it be hang in atleast once in every couple of week . I have to reboot it again to get it work .
810	CableModem	POS	5	when I have my cable install I know the moment the tech pull out a outdated rca modem I need to upgrade . the ridiculously slow speed come from say modem further prove my suspicion . I start research modem and come to the conclusion it be a 50\/50 crap shoot ... either it will work for you or it will not . I choose to look at Cisco because I already own a Cisco router ,  Cisco-Valet Plus Wireless Router  I be really glad I do . set up the Cisco Linksys modem be so easy , I have never have a modem\/router set-up so fast and easily . all I do be plug everything in , swap it out with my cable company online , and voilum I be online ... and my online speed jump from a crawl of 2.5 mbp ... to blaze fast speed of 12mbp and up . if you be have problem with you cable internet speed , odds be its the modem they provide you with . I dump my cable originally because of lousy speed , and go back out of necessity . if I have know I could have resolve my issue with a new modem I would have do this year ago , and save myself countless hour of customer service call .
144	CableModem	POS	4	very nice one . it suit my need and up to the expectation . Easy to install and be satisfy with the product
207	CableModem	NEG	1	I buy a refurbish Linksys router and it have work well now for over a year so I feel that buy a refurbish Linksys modem be a fairly safe bet . how wrong I be . as instruct I call comcast to give they the Mac address of the router however could not get the modem to show up with comcast . we try for hour with several different technician and supervisor but to no avail . add to this there be a no return policy for this unit . do not waste you money .
365	CableModem	NEG	1	I receive a package with the cable modem , 1 usb cable , and 1 ethernet cable , but no power adapter . I be now look into return the package for a full refund .
255	CableModem	NEG	2	buy it in Nov of 2009 . I have internet problem for several month and even have Comcast out to check my signal . they say everything be ok . I notice that the modem be warm to hot to the touch . I buy a Motorola modem and now everything be fine . would not buy another Linksys .
149	CableModem	POS	5	install be fairly easy - have to call charter tech and they walk I through it & in 10 minute my internet be download 33 mg uploading 4 + mg - wow ! Super High speed ... Getcha some
578	CableModem	NEU	3	on the good side , when it work , the basic internet connectivity work fine . I have have it for half a year now connect with Comcast , and never have any connectivity issue -lrb- unlike the comcast-provided basic Motorola modem -rrb- . on the bad side , it be the third unit by now . I have buy it at BestBuy , and they have be replace they without any question by just stop at the store . good luck shipping it back and forth if you buy it online . the first one have the cable connectivity and ethernet work fine but the WiFi just be not there , be not even show in the config menu . I have call the support and they have say to replace the unit , so I do . the second unit work fine for half a year until it die . there be a big thunderstorm on that day , which might be relate . it be be connect though a UPS _ and _ a surge protector , so the power line can not be the issue . and I have have a laptop sit next to it , plug directly into the wall , connect to WiFi . no problem with the laptop , the router be dead . perhaps it do not have the adequate protection on the antenna circuit . so now I have the third unit , again replace by warranty , and so far it work fine again . the other bad news be that it be quite feature-poor . no comparison at all to the router that Verizon provide with fio -lrb- and mind you , at no charge , unlike Comcast -rrb- . it can not do static address in the lan -lrb- you can leave a block for static address in dhcp but you can not hardcode fixed address in dhcp -rrb- . it can not do the local dn domain for the LAN . you can not assign symbolic name name nor fixed address to you dhcped machine . so if you have say a networked printer , reach it become not exactly straightforward .
820	CableModem	POS	5	after Comcast increase my rental rate for they modem to $ 5\/month and after 8 year , decide to buy my own modem . Works great and be rather easy install . if you be on a mac and use wireless , it be much easier to use ethernet connection for the initial hookup .
173	CableModem	POS	5	I have be use the 6121 modem with Comcast 's Xfinity internet service over the course of several month and so far everything have work perfectly with no problem . datum speed be typically 20-25 mb\/s download and 3.5-4 mb\/s upload . I buy this unit because I have read account of reset problem and other glitch experience by user of earlier Surfboard modem model , and thus far , it have meet my expectation for problem-free use . I feel the need to comment on the unit 's warmth , since other user have criticize this unit as become excessively warm during operation . maybe those user receive faulty unit , but my experience do not square with theirs ; I have put my hand on the unit multiple time to feel its warmth -- in my opinion , this unit do not become any warmer during use than any other electronic network device , include wireless router and voip adapter . I have use earlier surfboard modem -- the great 4200 and 5120 -- and I can honestly say that this unit do not get any warmer than those earlier model . it be slightly warm to the touch , but not overly `` hot '' at all , and I feel this be totally normal for this type of device . so , I be not concern with this aspect of the unit . once the modem be up and run , you can type 192.168.100.1 \/ index . htm into you web browser in order to reach the status page for the modem and view useful network statistics .
529	CableModem	POS	5	I have a 8x1 cable splitter -lrb- cable to each room -rrb- and a splitter for broadband -lrb- before the 8x1 -rrb- . in addition , I get a tv tuning card for my pc that have separate input for analog and hd , so I need another splitter -lrb- after the 8x1 -rrb- . too many splitter be lower my video quality and make it difficult to receive hd signal on my tv tuning card . I leave the first splitter for the broadband -lrb- install by the cable co. -rrb- so that my broadband do not go through the BDA . then I insert the BDA on the video signal before the 8x1 splitter . now every cable output work perfectly with low noise on the analog channel and no difficulty on the hd channel . I have have this hook up for about 6 month now and never have a issue . it be nice to order something that work just as you would expect and hope .
