Customer Ratings & Reviews

Works great! Internet speeds improved after upgrading to this modem. The app did not work for installation - I needed to call Astound, and was on the phone for close to an hour.

Simple to setup and full of the features you're looking for. This modem is compact and a breeze to walk through activation with Xfinity. The 2.5Gb LAN port allows access to most ISPs over provisioning enabling faster than 1gig connections.

Excellent modem and easy to setup. Would have given it full stars, however it took well over half an hour to connect and multiple attempts. Did boost my speed significantly and corrected a lot of connectivity issues from my previous ARRIS modem.

Future proof your Home With a super Trusted and universally compatible mainframe . Arris is trusted for years for the quality, simplicity, and value . This new model has a 2.5 GHZ for future proofing your home internet . Simple design And super easy setup via internet or App.

Very easy and quick to setup. I love the size of the modem compact and doesn't take up that much room. Performance it is great and have not had any issues.

Comcast stated we needed to get a new modem in order to utilize our high speed internet. We purchased this and it has been working great. It's a tiny modem so it doesn't take up much space on our entertainment system. No complaints and no more disconnects which is nice. I would recommend this.

Easy set up, bought as a rental replacement from Breezeline. Works great been using for almost 2 months now.

Works perfectly. Setup was very easy; just took a quick call to my ISP. Upgraded service from 40 Mbps to 200 Mbps and swapped in this modem for an older Arris Surfboard model. The extra Ethernet-out port is nice but I don't think it's supported by my ISP so I haven't used it yet.

Really liking this modem. Set up was easy and performance is on point. Size is great too, much smaller than my previous modem.

Dead simple to set up. Great performance. No longer suffering from the occasional unexplained loss of Internet access that the Spectrum modem was experiencing (and required a reboot to fix). Great solution.

The Arris just works and stays up. Farmmore likely to return to service after network failures than the modems the cable company provides. Also super small!!

Works great and was easy to set up. Our speeds went up by nearly 5x's over our previous modem.

Second time purchasing this Arris modem. Absolutely love it is efficient, fast and super easy set up.

easy set up works great with Xfinity has two locations with th same modem both work well

I plugged it in, when through the Xfinity/Comcast app to get it permissioned, took less than 3 minutes. It’s now been on and working flawlessly since the date of install. We get maximum down/up speeds as allowed by our ISP plan. Simple, easy, and just works!

purchased to replace a leased spectrum modem, COMPATIBLE, BUT REQUIRED A CALL TO SPECTRUM IN ORDER TO ACTIVATE ON THEIR SYSTEM. After connecting, speeds were initially super slow because the modem wasn’t registered with Spectrum. A quick call to spectrum customer service, and the rep registered the modem’s ID with the Spectrum system. Now I’m getting fast and reliable downloads. If it lasts about two years I’ll recover the purchase price.

The 1st ARRIS S33 unit we purchased was returned within a week because it kept rebooting. However the exchange unit we're currently using works perfectly. Thus the 4 star rating. 5 stars goes out to Best Buy for their great customer service and easy return/replacement policy. Best Buy is truly the best!

It has been 6 years since I purchased a modem. My old modem was working fine but sppeds began to lag. I have gigabit internet and a recommendation was made to move up to the S33. It is a very compact workhorse! I have had nothing but great speeds and connectivity with this modem. Hopefully it lasts another 6 years and I can continue to save on the modem rental fees from Xfinity! Would surely purchase again.

It was super easy to install and get it running. However, my problem was internet instability which apparently was due to coax line quality.

Really great quality product. Installation was easy, just plug it in and go. It smaller yet performs better than the one Comcast gave me. When you consider you're saving $15/month by owning your own modem it becomes a great value that pays for itself.
