Customer Ratings & Reviews

This thing gets hot and stays hot. I don't know if that affects speed but it always slows down after a short while. Also, it does not broadcast a wifi signal. You will need a separate device for that. This device is not impressive but it should be for the price. My Netgear modem/router is cheaper, faster and has dual band wifi.

Everything was very easy to set up, works great, no issues so far

This Arris cable modem is better than the modem so rented from the cable company. I’ve had no problems since I installed it. It was an ordeal to get the cable company to activate it but everything has been great ever since. Plus I save the $12 monthly rental fee.

A+. Easy to install and activate No regrets, recommend

When Cox makes you get another router to stay connected in 2024 i would definitely get v this again.

Was easy to install ,works great with Cox. I did everything over live chat with Cox the price was OK Would I buy again YES

Super fast and easy to install. Took about 5 mins and I was up and running and with faster Internet.

Installation and activation was simple. Simply plug in, power, coaxial to Xfinity and router then register modem with Xfinity via their app. Within moments WiFi is on. I can say my speed improved but the modem is compliant with Xfinity so I should be good for a long while.

This product performs consistently as promised/expected.

I love this modem! It is super fast. I use the 2.5 connection.

So far so good. No heat issues and it’s very fast!

The modem connects flawlessly to Comcast, and I am getting slightly over the 1200 Mbps download speed I'm supposed to get. That said, I am not getting the 200 Mbps upload speed I'm "supposed to" get from CC, but I imagine that is on their end and not due to the product itself.

I needed to upgrade my tired older surfboard 8200 modem. This S33 model was a direct replacement. I really like this model more given the support for 2.5 gigs off the internal Ethernet port. My firewall can handle up to a 10g connection so this worked perfectly.

Easy to setup and has been rock solid with Xfinity in Maryland. Getting 1.2 gigs down.

Works well so far after 6 months of use. Although its not necessarily an issue, the modem itself is plastic and somewhat warm to the touch. A lack of a cooling fan means that you want to keep this away from warmer areas of your house (closets, attics, etc)

With the right internet plan the speeds are accruate when hard wired! Make sure to use the right LAN port and youll get true 2Gbs speeds on the download. On the flip side, If you’re expecting 2Gbs speed over wifi you’ll be let down. But this is no fault of the modem… its because of wifi / router limitations.

Easy setup in minutes. Worked perfectly first time

No issues. Easy to setup. 2 fast ports: 1x2.5, 1x1 gb ports.

Easy to set up. Nice size. Connects well with Netgear products, which was bought at same time.

Check with your internet provider first. Xfinity was offering unlimited internet if you rent their modem. Unfortunately the unit they(xfinity) supply has built in wifi which I do not need(mesh wifi system already installed). This modem works as advertised I am getting the full benefit of everything i am paying for through xfinity with it.
