Customer Ratings & Reviews

This modemn was easy to connect and is compliant with Xfinity wifi. It appears to be reliable without disconnecting often.

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.

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!

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!

Excellent! Produces a very solid connection! No lagging.

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

Probably the fastest and easiest moden to set up!!

FAST .... RELIABLE... DOESN’T DROP CONNECTION. great modem

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

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

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).

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

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.

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

Works great and connects to the Internet flawlessly

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

Great product! Super easy install and has been real reliable.

This product is a great Modem for price, speed and features.

I would recommend this modem to anyone who wants High Speed Internet and or fast streaming! Do Not Use The Providers Modem! The ISP Provider Controls their modem by altering the Init Strings in the modem to restrict your data speeds. They cannot do this to a Privately Owned Modem due to FCC regulation of Modem Init String Tampering! You want the speed you pay for? Buy this FAST Arris Modem! Highly Recommended!

easy to plug in , called internet service provided new router information and it connected within a few minutes.
