Customer Ratings & Reviews

We had the s33 modem, but discovered that for faster Xfinity Upload speeds, we needed to upgrade to this. Once we did, our new 2 Gig plan works like a charm!! We have this modem plugged into the Eero Max 7 Wifi system and we are super happy. Modem setup was a flash, Xfinity only needed the modem MAC address and we were in business!

It does what it says on the tin and I can achieve a solid 2.5G connection from Cox Internet. That is where the positives end. This is a BYOD modem for almost all providers - that means you have to support it yourself. Tech support will basically hang up on you. This wouldn't normally be a problem except... The management interface configuration is utterly attrocious and becomes unavailable once the provider sends a DHCP lease. The only way around this is with professional grade understanding of network interfaces (SNMP particularly) and a non-standard router config. That is the only reason I don't recommend this modem - the average user will get a very discouraging experience with it from their ISP. I recall this not being an issue with my previous netgear AP (which wasn't mid/high split like this unit). The management interface was available through a router without pulling my hair out. ARRIS - if you're listening, please use the standard 192.168.1.1 starting range rather than 192.168.100.1 - or even better, auto detect if the LAN port responds to DHCP and just... get an IP like a normal device.

Great modem. Running at well above 500 Mbs/sec. I trust this more than the "free" s cable modem/router supplied by Sparklight. I got this based on a replacement via the BestBuy protection Plan. House struck by lightning . Limited number of indication lights as to older version but it works well. Go for it.

Easy to connect and setup. Completely fixed the issues I was having with my Google WiFi pro and old modem.

Easy set up and a great product. The best investment.

Imagine getting this super fast cable modem for free. Well, it's not free to purchase, however, with Xfinity fees eliminated this great cable modem pays for itself in just over a year. Given its advanced nature, it will be both paid for and then a monthly saver by the following year. Installation was a breeze. The small footprint is a bonus. Feel the need for speed?

Needed to upgrade to a new modem and glad we chose this one. It works well with our Google Nest devices as well as external security cameras. No issues with connectivity or performance. Would definitely purchase it again if we needed to.

Easy to install and connect with mesh router to provide fast connection throughout the house.

Very easy setup. Easy for cable company to activate. Very reliable performance.

The Arris Surfboard modem was easy to set up and performs well. The activation with my cable company was the longest activity in the process.

I've always purchased high end netgear nighthawk modems and wifi equipment. After Xfinity caused yet another issue with my netgear modem, I took a chance on the Arris s34. I'm happy to report that the speed is actually faster with this modem that is half the price! Thanks Arris!

Great modem, small package so it does not use a lot of space and it has great speeds. Only negative is that they don’t provide an Ethernet cable which is unfortunate but overall a good product.

Best Buy’s service was great! I really appreciate their router trade-in program, which gave me 15% off. This router works well so far — good speed and performance — but it does get noticeably hot during use.

So far its working fine, I have a gig plan from Xfinity but I'm only getting 800-850 when hard wired to my Nighthawk 5400 router Does run very hot over 120 deg.

easy to install, very fast, full throughput your choice of router or computer/server. great value for the money.

Works well, get gigbit speeds being paid for but can go faster for future. Easy setup

Great product easy install and works really good I would recommend

I truly didn’t think this would make that much of a difference and I was wrong was finally able to see my speeds increase. If you have a 1G plan then this will allow you to see what you are paying for.

Purchased this modem to upgrade my SB6183 to eventually get a higher download speed package with Xfinity. So far it works flawlessly. Already getting a bit higher download speed.

This modem has been great. Effortless setup and very reliable.
