I bought a Netgear cm1000 18 months ago. I had concrap come out to see what was wrong with my internet. They said the modem crapped out. That was a omission of the truth. They removed it from their official support list in may! No heads up, just killed it. Arg.. they wonder why folks hate them so bad.

For what I can figure is the new game with modems is OFDM and OFDM-A found on a lot of DOCIS 3.1 modems now. 32x8 is no longer the one to look for I guess. Well at least for concrap. 18 months only to have them orphan it makes you wonder if it was on purpose since we do not lease one from them.

Yep, I was all over those 8611 Xfinity forums when my 8611 started dropping off line every 10 minutes Dec 2022. It was embarrassing esp on work video calls.

This was 10 months after nothing but bulletproof performance.
Neither Motorola nor Comcast took responsibility, leaving all 8611 users SOL.
Had to replace a $200 modem after 10 months. Crazy!

Reviews are irrelevant and most are left within 30 days of purchase when people are still happy with it. There are enough problems cited by Xfinity users that it's not just anecdotal, there's a problem with the device or its firmware that Xfinity itself has acknowledged.

There is a reason for the fire sale on this device.

The fire sale part worries me. I bought it last October and it is working solid on Xfinity. For how long, we will see.
