Customer Ratings & Reviews

Bought this modem to replace my Comcast modem. Glad I did, the speeds are noticeably better with this modem. I did give up voice function with this modem, but I never used our Comcast phone line much anyway. This doesn't really save me any money on my Comcast bill tough. The way they work it, if you pay extra for unlimited data, you save some money on your monthly modem fees, but when you buy your own modem, that discount goes away, so my monthly bill actually went up a few dollars. Oh well, still glad I bought this modem though. It's a quarter the size of the Comcast modem, and even made by the same company that made the Comcast modem. Setup was easy using the Comcast iPhone app.

Overall has been amazing. Constant speeds and no outages. I have spectrum gig and this gets the job done.

Xfinity recently upgraded their system and my old modem only downloaded 300mbs. So, I upgraded and now I’m getting 900mbs on busy days. Works flawlessly too…

I replaced an older Arris modem/router with separate pieces and to take advantage of my 400 Mbps service as my old modem was only good to 300 Mbps. I had read several online reviews/warnings that it could be difficult to provision the S33 with Xfinity service. However, I had no troubles using the Quick Start method. No calls to Xfinity or Arris as some others experienced.

Easy to set up - smaller than other devices - one single status light with different colors instead of a row of flickering lights that also have different colors - and 2.5GB AND 1GB network ports.

S33 is small but packs a punch with great speeds. Also a good looking modem. You can’t go wrong with this modem.

I have had zero issues with this modem since purchasing it over a year ago. The setup was easy as well.

Works great and is easy to trouble shoot. We’ve hooked up quite a few extenders and they have worked with no problems.

Our streaming has been so much better, and faster. This modem not only looks good, but it really makes our gaming and our movie nights that much better. This was super easy to set up, and connect to.

Easy to set up . fast, consistent reliable never overheats

So far this has been a good fast modem. Other reviews online I read said that it was a good reliable product.

Works as advertised for my Xfinity internet. Easy to setup and get running.

Purchased to replace a Netgear that died after a power outage, at the recommendation of Xfinity technician. Easy to install, works without a hitch, Was concerned it gets too hot but so far that has not happened.

It's a cable modem. Easy to setup through Xfinity using the Xfinity app. The Surfboard app is worthless, but the modem is reliable and much better than the Xfinity junk they give you.

Getting the fastest internet speed I have ever had with this modem. Very happy with this modem.

I was using a Spectrum provided modem and constantly had issue with it. Even had a technician come out and check the line. No issues with the line. I decided to purchase the Arris Surfboard S33 and I'm extremely glad I did. I've had absolutely zero issues and I couldn't be happier with my decision. Speeds are maxed out per my internet subscription and I've not had any issues at all. Very pleased with the ARRIS - SURFboard S33 32 x 8 DOCSIS 3.1 Multi-Gig Cable Modem with 2.5 Gbps Ethernet Port.

This modem works great, perfect for getting the most out of you r internet speed.

Wanted to replace my outdated Netgear modem as it could no longer keep up with my gigabit speed Internet plan. Bought this on sale and had the Best Buy recycle discount as well added. So the price was great! Installation was straightforward; plug and play, and activate via Xfinity. I was connected ands online in less than 15 mins.

Great router and it does was it is supposed to. i replaced my router which was over 5 years old. Setup was very easy and I was up and running in a few minutes. I was impressed that this new router increased my speed by almost 300mbps. I run the router with an orbi mesh system. The arris s33 has 2 ports. I have one port used for home internet and the other port dedicated to my home alarm system

This is a solid cable modem and very easy to setup. Its a great replacement for my 8 year old Arris modem. Pleased with the performance.
