Connecting to Cox gives a false not compatible message
For Cox customers, when I setup my modem with cox, at the finish it was saying that it was not a compatible modem with Cox Service, but it was functioning fine. We were connected to the internet and everything was green on the Cox side. (I called to verify it was compatible)

Excellent router/modem, been reliable so far, cost savings, smooth set-up
Arris G18: it’s noticeably faster and robust compared to my old one (which was a dinosaur though). Basically doubled my speeds. Set-up fairly smooth/easy; didn’t have to call Xfinity once and entirely connected using “new equipment” steps online. My HP printer is old, 2.5mbps, and wasn’t obvious at all how to connect to the new network. Done through Arris URL, settings where it “finds” the printer and I easily added it to the network - worked perfectly, problem is it’s not obvious how to do it. Also very pleased to purchase for $60, Amazon “like new” and save on Xfinity rental fee.

Would discourage for intensive multiplayer.
it works as well as a basic modem router combo should, if you are looking to do multiplayer gaming, i'd recommend doing the G20 version at least for the increased upload speed. But if your doing general internet use and singleplayer experiences, this will work. You will be required to make use of a phone app, SURFboard. And the app is a bit weird at first, and really i would give this product 4 stars if the app was specific to this modem cause there's a setting allowing you to combine blah blah and blah blah and until you switch this on you will feel like your just making passwords for nothing. Your ISP, for me was Spectrum, may also offer a free cell phone and cell phone service as part of the internet service.

Didn't work. -- no Internet connectivity through WiFi, and 2 aborted setup attempts
Setup aborted prematurely, and I could never get the WiFi access to connect to the Internet. I don't recommend this item.
