Customer Ratings & Reviews

So far, it works as advertised with our 1Gbps Xfinity cable Internet. Setup was easy, went to the Xfinity website, registered the modem and got everything to work under 20 minutes.

Had a Spectrum modem, speed was terrible. Purchased this Surfboard modem and speed is now INCREDIBLE. Ditch the Spectrum modem and get the speed you’re paying for.

Arris modems have always been good, and I bought this modem to take advantage of 1.2G Internet Connection that my internet provider upgraded for me. Just work, no complain whatsoever.

Easy set up, does what it has to. Not much to play around but pair it with a eero router!

If you have a high speed internet connection and want a good solid modem- this is it. This does not have a home phone connection. It works really well when paired with with a solid Mesh Network or a High Powered Managed Wireless Network.

Instant difference! I upgraded from a modem/router combo and this made a huge difference!

Works with Spectrum service in MKE. Keep in open and well ventilated location It gets warm.

Works well but had to contact Comcast twice to get them to set up their end of the software. No problem with 200 mb Comcast service. Don't blame ARRIS for Comcast issues. After setup works no problem.

Purchased this because my internet was down and I wanted to make sure it wasn't the modem. I have the quick speed from Spectrum so I don't pay rental however I decided to keep it, guy from Spectrum said it was a good one. It only became listed as an approved Spectrum modem this past September. I do enjoy it's much smaller than the Spectrum issued box. I am only skeptical because I feel like internet performance went down since install. The repair tech said that they were having speed issues with everyone at home but I thought it was odd he would show up and we would slow down a little.

Great upgrade over my 5 year old modem. I was getting about 400mbps before on a 800mbps plan. I got this new modem and it shot up to my 800mbps. Only downside is the app is terrible but you never need to use it.

Great product. I get more internet. I’m using Xfinity and it’s 100% compatible. Highly recommend this product.

Excellent modem. I am always getting great wifi with my new modem and a plus since I have the Google mesh around my house. Easy to install and very simple modem.

Easy to setup and use, it's extremely fast if you have the proper internet speed. A little bit of overkill but it pairs well with a Wi-Fi 6 router to future proof your home network. It also reboots in a minute or less. My only issue is it required a hard reboot every week to maintain high speeds.

Does what it says on the box. Not sure what it’s actual max download capability is, but it handles gigabit cable great.

Great product, easy setup, getting higher download and upload speeds than with my original DOCSIS 3.0 modem.

Great purchase, bought when my previous modem was failing. Traded in old one for 15% discount and my internet is doing well.

Excellent product. Set up was fairly quick and easy once I got a rep at Cox communications to recognize it was one of their accepted products. I have a separate router and I did have to do a factory reset before everything was good to go.

I kind of was forced into buying this by cox cable. They said they were upgrading their infrastructure amd they were going to charge me more if I didn't have a newer modem. Anyway, this works fine and is fast. No issues with quality or connectivity.

This is by far the best Cable modem in the Market. one of the only one that gives you a 2.5Gbs connection.

My old Netgear CM1000 v1 was no longer supported by Comcast. It was still working but decided to upgrade. Went with the S33 and very happy. Noticed a slight increase in download speed for the Blast tier.
