Customer Ratings & Reviews

Great step up from the S33. Same download speed as prior model, but 10 fold increase in upload speeds! Consistently getting 150-200 Mbps upload speeds now, and sometimes up to 300 Mbps.

Upgraded to this modem after upgrading my service plan and this was listed as compatible with provider and new plan. Not yet achieving the expected down data rate but the up data rate exceeds the expected speed. The lower than expected down data rate is unlikely due to the modem.

Working well throughout the house even several months later.

Definitely a great modem, but the web interface needs to be more secure as both the router and browser complain that it isn't secure. The Energy Efficient Ethernet is a great feature, but it would help to be able to turn it on and off easier. The worst thing about is the app they recommend you use to setup and register it. It's much easier to skip the app and use the web interface to register and set it up.

Performs exactly as I’d hope. I wanted something I had a little more control over than cable company provided equipment and this fits the bill.

Finally, the speed I've been yearning for 2 gig downloads/uploaded for the money i have been spending for years ... 2300dn/ 375 up, thank you, Arris

Faster than the one given from Internet company., would most definitely recommend a purchase to a friend.

This arris Really handles the speed that it advertises

As described. Easy insrall. I use mulitple devices and ut works great. No issuse.

Fastest cable modem on the market. Upload to Download information.

Provides upgraded speed compatible with higher speeds offered by internet provider

I bought the S34 modem believing my router (capable of 350Mbps) would still allow me to reach into the 150 Mbps range. My outdated old modem only gave me 28 Mbps and the S34 bumped it up to 38 Mbps. I'm either missing something or Xfinity has me throttled. I'll update this review if I figure out a speed increase.

Increased speed in my home significantly. Didnt need a modem/router bc I use a net system to reach everywhere in my house.

The product operates great, and was an easy installation. The product was Cox compatible.

Worked with with the network equipment I have. Purchased this as a back up as our previous one broke. Now it is our permanent one.

So far I really like this 3.1 Arris S34 . It is a newer release modem and not one that has already been out for yrs. Read reviews and glad I didn't listen to those who say it gets hot. Sit mine on an open air trivet and it stays just fine.

I recommend it, it's easy to install and configure, it works perfectly.

Quick and easy install with xfinity service. I was able to connect it with the app.

The modem installation was finished using a process from my cable provider and has worked as advertised ever sense.

Overall great modem and I I noticed my download speed increased. It’s a overall great powerhouse modem
