Customer Ratings & Reviews

Keeps dropping out and im probably going to have to get a factory replacement.

Works great when it connects.... has difficulty communicating with a gigabit switch/router sometimes... even if it has a "solid connection light" ...... I might switch it out with another good thing I got protection plan.

Easy to setup using the smartphone App. I had to contact the service provider but everything was easy.

Very nice router. We have it for our xfinity wifi. Works very well with our mesh system from tp link

Had a Netgear CM1200 and decided to upgrade. Charter Spectrum activated the modem and I was online. Problem is though, it would constantly drop on/off online. Charter could see it on their end. Since my previous modem was working fine, I knew it was defective. I also wanted to note you cannot view the modem page if using a router. It will be blocked. I returned the modem and picked up the Netgear CM2000 and everything is working perfectly fine now. I can also access the modem page with no problem while still using a router. I did like the small form factor of the Arris S33 modem. That was about it though.

2 weeks after the return period ended this thing starts losing connection every night. The ISP blames the modem and now I’m out $300. Great.

Great modem, easy to setup and performs well. Registered online with Xfinity and that was all.

Easy installation with xfinity throught the xfinity app. Works great with eero mesh system.

Our other one stopped working, had to do research trying to find one that would work for my situation, so far it has not let me down.

Overpriced garbage. I bought this for my new home to support our high speed internet needs for working at home, as well as multiple users. Here I am now with a failing modem at not far past my return window, so I get to eat this pricey purchase. I had an Arris previously that I thought served is well, but will stay away from low on.

In the beginning I would have given it 5 stars, however I waited which I am glad for. After 4 months of it running the internal system went bad. Had to return and get another one. The reason for the 4 stars really is because of Best Buy’s amazing service plans. If it’s broke they swap it. At least for items like this that is what I have seen. Got the new one installed and everything setup and it’s working like a champ, currently on month 5 so hoping it was just a bad part in the first one

Working well with mediacom. Have 1 gb line, geting 700mg on wiered connection

No issues here. Pretty easy to set up and good connection to my mesh routers.

Do not get this to work with Xfinity gig speed as it is not compatible with it, Xfinity blames Arris, Arris blames Xfinity.

I have 1 gig plan. This modem can't get faster than 325 mbps. 3 different techs tried everything. Could be Cox, could be this modem, not sure but it didn't get the job done.

This modem lasted less then a month and the went out. It was trying to rest it self all the time spectrum couldn’t even run a line test. I ended up going with a Motorola hopefully that will be better.

This modem is perfect. Finally able to connect to high speed internet.

the best modem your money can buy. it is capable of great speeds!

One of better modems to use with Xfinity service especially Gig.

Easy to install with app. Worked immediately. Would recommend.
