No cosmetics issue on the modem which was nice, but when I tried connecting it to the internet it would not work. I even called Cox for help and after an hour with them, we came to the conclusion that it was the modem that was faulty. I did purchase it from Amazon's "Used- But Very Good" where I read comments that they were in perfect condition so I took a risk. I am too late to return the modem so I am out of money too. If you are buying this used, I would think twice.

I can’t connect to the modem

It fully stopped working after 5 months using. It was a pain as it disconnected frequently in the past 5 months.

Not setting up with Xfinity at all, Arris app is utterly useless. It's 2am and I got a headache from trying to set this up. Get a different modem.

This modem is not compatible with Xfinity. I tried a few times to get it this modem registered but it isn't compatible. Save your save time and hassle and look up the list of compatible Xfinity modems online. Smdh

I took it out of the box, plugged it in with the included power supply (that was in an already opened bag inside the box by the way), and it didn't power on. I called support, gave them the serial number, and they said it had expired in 2019. I purchased this in September 2023. Amazon sold me an already expired product. Returned it, didn't want to deal with the hassle.

Product does NOT work with Comcast.

Connection was bad, contacted Arris to get help and learned it was 7 years out of warranty and used to be an ISP loaner. Beware.

My cable company said my modem was defective. When I requested this seller for a proof of purchase invoice I got nothing but crickets. THIS SELLER SUCKS!I had to buy a new modem myself.

It’s been only 2 years and this just stopped turning on. Not even using it at its full speeds, so it should have had very low resource utilization compared to what it’s rated for.
