Customer Ratings & Reviews

Was recommended this product by one of the helpful Best Buy staff. Very easy to set up. So far I have not had an issues with it. If you are not comfortable with computers the instructions are pretty good, so you shouldn't need to ask for help. I like that it is small and the lights are bright. Hoping it lasts a long time.

Great Modem for home or business use. This modem is solid, fast, reliable, and very user friendly. I have used this unit in both residential and commercial applications and it has outperformed every ISP provided modem i have encountered.

It is working with Comcast 3.0 but the first time I tried to set it up, there was a problem with the wifi connection. The internet buffers a lot. The modem works just fine. Probably something wrong with Comcast. The price is not worthy for such a produt

Why pay comcast 7 dollars a month when you can get a Motorola modem it perfect for your internet and it's really fast easy to set up too took me only 5 mins I upgraded from my Motorola modem/router all in one and this modem is really fast

I replaced my SB6141 with this unit. I am now able to get more than 200Mbps from my internet provider, which is awesome. If this unit performs as well as the SB6141, I will be happy for years to come. Definitely recommend the upgrade

Modem performance is very good, getting some one from Comcast to provision it properly or getting full bonding on all available channels is unlikely; unless you are in a fully activated area and you are lucky enough to get proper assistance from knowledgeable representative. ipv6test.com may not initially recognize capability & you must make sure router & other devices are set to ipv6 compatibility modes. This can be challenging, because all things may appear correct, but ipv6 may still not connect. There may also be some lag time before devices are initially recognized. This modern does it's job and will serve you well once you get through the pain of setup. I do highly recommend it. Motorola customer service is very friendly, professional & helpful -should you need them - they will answer your lingering questions.

Best Modem you even own. FAST, Easy installation. All you need is WIFI router and hook to Modem. No problem. Important to purchase ONLY MODEM not built in WIFI and Modem. too much problem and complex happen. Just MODEM and you are all SET!

This modem is great. Basically plug and play, super fast, and reliable. For the price, it works great. One possible downside for some people is that it has a blue light always on which looks kinda bright at night.

TWC upgraded my internet service to 200/20 so I had to upgrade from my old trusty SB6121 to take advantage of the new speed this modem has been rock solid I have had zero issues.

I bought this for my father, to replace his rented equipment. The setup was a no brainer. There has been no experienced no connectivity issues. Upload/download speed is noticeable faster.

This is a wise purchase and very easy to setup The price is fantastic! It is also compatible with your cable server.

In order to take advantage of higher speeds from my ISP I needed to upgrade my existing modem. This model was on their list. The price was good and it works great. I have had several Motorola Arris models. No problems were ever noted.

Bought this modem 3 years ago and it’s still going strong. Definitely better than paying for a rental modem from cable companies. Haven’t had any issues and setting up was easy.

Bought this to go with my Netgear router. Recommended by the sales person. It is supported by Oceanic Time Warner Cable. The setup was quick and trouble free. Glad Im not paying equipment rental and getting much faster performance.

Bought this unit to be done with TWC's rental. Its compact size clears up a lot of space on my desk. It's white like my Apple router and it was a breeze to install. The sales rep steered me right when he said to get this one.

Easy to install, fast and trouble free. After buying this, using it for awhile, and being impressed with the performance and trouble free installation, I recommended it to 3 other people who also bought it and are happy with it.

This modem works perfectly. Its performance has been rock-solid, and I've not had to reset it once since I installed it approximately 6 weeks ago. Download and upload speeds are outstanding. You can't go wrong with this modem.

We purchased this in place of our spectrum modem. This one is compatible with spectrum systems and is way more reliable

You get what you pay for. Replaced my old Zoom modem with this speedster, went from 30m down to 120+. Super solid, easy to set up. Works great on Comcast. Highly recommended.

Wow! This is sooo easy to set up. A perfect fit for Xfinity connection. The wifi output has been seamless at top speed. Best of all, I'm saving cool cash every month on my bill.
