CM1000 Xfinity issues
I am quite frustrated at this point. I had a CM600 modem to support Comcast's Extreme 150 service. I've had it for a few years and was consistently getting 160 to 170mbps speed from it. About thre...

I got a second call an hour later that the issue was fixed. I ran a speed test and got a consistent 160mbps (yay!). I used the reset button on the modem and let it re-provision.

I have been having issues since mid December. My CM1000 won’t lock on to the network, I was told today that is my problem not Xfinity’s. I think I’ve had 5 technicians out but nothing has been fixed. All of the connections have been replaced, I’ve bought 3 new CM100 but none of them work. How do you update the firmware on the modem?
This is REALLY frustrating.
You can’t. Xfinity pushes down their version of the firmware when they provision the modem. 3.01.04 is the latest
