Question: Will this wireless modem work with Comcast Cable? Also this is a modem/router (All-in-one)?
Document: After purchasing the Cisko Lindsky's BEFCMU10 modem and Comcast not excepting it, i bought this one and it was a little more expensive and costly to have Comcast to set up my broadband desktop and also my wireless Kindle Fire tablet! So, I am well pleased that this ARRIS/MOTOROLA SURFboard Gateway SBG901 DOCSIS 2.0 Wireless G Cable Modem is able to work both the desktop that is not wireless and the Kindle which is! Super and very happy with it!
The system works great, just follow the direction. I had no problems setting up the device. The modem and wireless router work very well together as one device, no need to have separete modem and router with this thing. Also, it pays for itself for what the cable company charges for its yearly fees.
The wireless cable modem was easy to set up. Had no problems connecting all my equipment. I am just really impressed. Have been using a month and no problems. I have a wireless desktop, wireless laptop and wireless HP all in one printer. Love it. I also have an older desktop connected to the ethernet port with no problems. Great product and the price was reasonable. Plus I get to stick it to comcast with no equipment rental.
This modem is easy to set up, fast, and inconspicuous - I really like not having to buy a separate wireless router for my internet. Word of warning - if you're having your internet set up by your provider, be sure to plug in and configure the modem before they come over. Otherwise they'll claim it doesn't work and try to leave you one of their lease modems, and you'll have to spend half a day in line at the stupid Comcast office. Or maybe that was just me.
We bought this to stop connection issues with Comcast!Had an older Motorola Surfboard modem and a Netgear wireless router.We had to reset them often to get the connection again.Now that we installed this new Motorola modem wireless router combo we never have to reset the cable.We have great constant signal in our home everywhere now! We have wireless laptops and printers!All work great!The only negative thing is you cannot change the security code which is rather long!
It is nice to have one unit to replace a wireless router and a cable modem, I highly discourage this one in particular. I've had nothing but problems since I bought it. Connection is extremely slow and constantly drops at random times throughout the day. I know it's not Comcast because this problem only started happening after I purchased the unit.
I got this modem two weeks ago, reading all the reviews which I only focused on the positive one and how its DOCSIS 3.0 and known brand and also approved by the cable company (comcast) made me buy this product. I have the performance package from comcast 15mbps down and 3 mbps up with the old modem that I use the internet speed test is showing 14mbps up and 2.8 mbps down.
I needed a modem that would connect as a fast cable modem and also work for my wireless needs at the same time. This modem met all my requirements and has worked without a hitch. I did have trouble with setting up the wireless part but I am not very computer savey. If you read the instructions carefully then you will figure out the solutions.
Purchased yesterday and set it up without any problems. It is now compatible with Comcast. This was an issue previously, but Comcast has now certified its use. Performance is great and very convenient having build in wireless, no need for a separate router, especially if you are mostly wireless, which my family is. I also ran several speed tests and got up to 20Mbps download and 3.4Mbps upload. Very pleased and a dramatic improvement from my older Comcast supplied Scientific Atlanta Modem. Highly recommended! !
Modem and router in one couldn't get better than this. The setup is easy and stress free. I'm so happy I purchased this product. It saves space and money. Also less wires to deal with. It's much cheaper than buying the two products seperate. And way cheaper than buying with the cable and internet company. I reccommend this to everyone.
Answer: Yes this works fine with Comcast and Charter (or any cable internet company), but you can't use it with their telephone service (so if you sign up for internet and telephone you have to get a different model). This device is an all in one with included WiFi, which makes it a great small device that covers all your bases.It isn't DOCSIS 3.0, but that doesn't matter since Comcast speeds don't even reach the capacity of DOCSIS 2.0
