Customer Ratings & Reviews

Upgraded to this modem from older Arris. I’ve had it a little over 2 months now and no issues or complaints. Some reviews complained about how hot the modem would get. We have on average 14 devices always connected to WiFi and it doesn’t get hot. It’s warm, but never hot. My old modem was always warm too. Feels relatively the same.

Great modem (we have Cox as our provider), easy installation

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

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

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

Happy to be rid of service orovider’s modem. Arris surfboard works great!

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.

Replaced a bricked NetGear. Should have stuck with ARRIS. This works and does what it is designed to do.

Easy to setup, works seemlessly with spectrum, just had to call and give them the info off the bottom of the unit. Soon as they sent the signal and rebooted it, it works like a charm. I actually get speeds over what I pay for with it. My subscription through spectrum is 500mbps and I generally get around 550 or more. Way faster than my old cable modem.

Seems to work OK so far but runs really hot. Hoping it holds up. I got this to replace an old one xfinity said wasn't capable of the speeds being provided, but I haven't noticed this new one being much faster. My youtube streams are at HD more often now, That's about it.

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 My outdated old modem only gave me 28 Mbps and the S34 bumped it up to 38 Mbps.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.

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

Works fairly well. No issues outside of setup being a bit much.

Finally a modem that provides the speed I need without dropping connections!

Router works great! Connection was easy and no delays.

my interwebs speed is as fast as usain bolt, good modem

Great modem better than netgear the best on the market

Good modem..im a tech for the cable company anf i apprive.

Easy to set up. Follow the directions (yes, read it carefully), and I had no problem with using the App to register.

Works well and has good range, even in my block house.
