Question: Is this a wireless Router and Modem or router only
Document: With the Motorola DOCSIS 3.0 cable modem, this router double my wireless network speed. I easily handles 2 Netflix feeds, a laptop, and 2 smartphones simultaneously.
I bought one from Sam's Club on Black Friday for a upgrade of my old tp-link WR841N which only have 2.4G.I'm very disappointed with the performance of this router. The wireless speed is slower than the tp-link right after I connected this router to my cable modem.
No more finding out when its too late that they were up all night during a school night playing games online or doing Facebook with friends!! I don't have to pull the cables or turn off wireless manually any more! Lastly, the performance seems to be better when I switched router functions to the new Cisco N600 instead of the ATT modem. The Internet speed seems faster and there have been ZERO glitches or need for reboots.
Setup was pretty easy as mentioned. Connect everything (including the modem) and follow the steps on the CD. Pretty simple. Once I had it up and running I was dissapointed with it's abilities. The signal was the same at best, possibly worse. I was expecting it to be stronger than my WRT54G with the new wireless N technology, not the case. This wasn't the biggest issue for me though. My problem was the speed at various distances from the router.
I get 50Mbps+ from my modem and the wireless speed via this router is around 3Mbps in my bedroom. I have done a firmwire upgrade from the Linksys site, hard reset etc etc. This is sick .I am returning this router and asking for a 100% refund. Dear Amazon please stop selling these junks in your site to I am big fan of Amazon .
We currently had an order router which no longer could support all the devices we have. My son did the research and found this router which would support our busy household. Setting up the router wasn't an issue, (we had to have the cable company reset the modem), then it worked fine. I was having trouble connecting to our wireless printer. After numerous tries, I shut down the firewall and anything else running, reset the router and then the printer.
Just bought this to replace a dead d-llink 615 router. Setup was straight forward. You need to know if your modem is modem only or modem and router. I have a DSL westell modem/router. This means if you buy a new wireless router you have to choose which is going to function as the router... The current modem/router or the new wireless router. It's easier to leave the westell as the router. So out of the box...
Although the D-Link card is a 2.4ghz band adapter only, it is getting a better signal than it did from the Verizon modem/router we had been using. It's connecting at 300mbs, dropping occasionally to 150mbs, but that handily beats the 54mbs it used to get on the WiFi G standard. Our other computer, a laptop, is constantly getting 300mbs and full signal strength with its internal Intel wireless adapter.
Upon first receiving the router I incurred several major issues. After running into these issues, I immediately updated the firmware. The updated firmware resolved the initial problems. Both the speed of the wireless connection and the fluidity of the configuration interface have improved since the firmware update. I've now had the router for several weeks and it has worked rather well, only having to reset it once, which may have been an ISP or modem issue. The range is decent, but not amazing.
The tech support then went on to blame it on a poor WiFi signal strength and couldn't seem to understand when I told them that I don't use wireless to connect the router to my main computer which also loses the internet connection. I would typically have to reset the modem 10+ times per day and after a week of trying everything asked for a refund from Amazon.I instead bought an Asus RT-N66U and couldn't be happier.
