Customer Ratings & Reviews

Finally getting the speed that I am paying for from xfinity. Nice compact design and easy setup.

I really like this modem. It has performed better than the previous modems I have used.

There are not many Internet Providers that send speeds to 1.2GB of downloading speeds, but the price was right when I purchased it for about $110. I wanted something that can distribute appropriate bandwidth throughout my spatious home and this piece of technology is able to fullfil that. The speeds I pay for are for 200 mb/s and my download speeds vary from 115-195 mb/s wirelessly. In wall initiation is the full 200 mb/s. Great modem!

Had one that worked great, but it was destroyed in a lightning strike, so I purchased the identical replacement (this one), and it works great just like the one I replaced.

I've always owned a dual-band WiFi router. The speeds I pay for and the speeds I get are laughable. As soon as I set this up, I noticed the lightning fast speeds! I can't go back to a dual-band after owning this. Initially, it didn't work but I discovered I had to inform TWC of the new modem so they could "activate" it. That part was annoying. I had to call ARRIS, who told me this. They have amazing customer service as well.

Easy to install and perfect for all our needs. I recommend this modem for all home uses.

After having issues with my previous modem/router I decided to simplify by purchasing this modem and then adding a google nest WiFi mesh. The modem is perfect and works seamlessly with the google system. I would suggest this modem to anyone who was trying to get the faster speeds without complications of having a modem/ router over heat and shut down.

This modem has worked without an issue so far for me, and it has worked very well. It can easily handle a high load from gaming, web-surfing, and streaming all simultaneously with room to spare. And given its technical specifications, it is ahead of the curve and should continue to work well even if my service provider upgrades their internet service (charter communications). It is a great way to help future-proof your internet equipment setup.

I was going to wait for the new Docsis 3.1 modems, but decided to go with this one. I've tested this at a sustained 150Mbps down and it keeps up without issue. I guess the best complement I can give is after I installed the unit, I had to do absolutely nothing to it. It just worked. The broadband modem has a nice status web page that shows power levels (this is useful if your cable provider goes out-of-spec in cold or hot temps).

I have had this modem since July 5th it was easy to install and so far meets all my expectations.

Internet was running slow so it was time for an upgrade. Easy to set up and Internet works fast again.

works with spectrum in my area.a lot smaller and a lot faster modem than the one they issue!

Plugged it in, called in the MAC, works ! What more could one ask for ? Great modem.

Great modem and easy to set up. I'm getting great speed with this unit. Works well with my router.

ARRIS continues to meet their quality expectations. Excellent speed and set up was a breeze.

The modem was very easy to set up, and it works flawlessly.

easy to install and setup increased the speed of our wifi

Solid Modem. Been using it for about 2.5 years now, still going strong. Only minor issue is I managed to lock myself out of the UI and it won't let me back in. Factory reset and everything. I'm sure I could spend some additional time and effort to get it unlocked again, but honestly, its operating flawlessly the way it is.

We were upgrading our internet speed and needed a faster modem. Found this on the Best Buy web site and it looked like just what we needed. I mentioned it to the cable installer and he agreed it would work with our new service. Hooked everything up and I haven't had a problem considering we have 3 laptops, 3 smartphones and 2 tablets running in the house.

Picked this up to replace an old SB6121 that wasn't keeping up with Spectrums speed increases. Installed it called to get it registered. Took all of 10 minutes. Download peed increased from 112mbps to 235. If you are paying for the speed but not getting it replace your old modem!
