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...
Well it is finally fixed. The tech showed up today and I showed him the two frequencies that were having the problem. He checked outside, and then at the tap. He came into the house and said he needed to call a bucket truck in to fix it. I got a recorded call from Comcast that they were working to fix the issue. 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. All the signal/noise and power levels were good and there were no uncorrectable codewords. They didn't tell me what they fixed, but at long last, it is fixed.
this speed issue is not caused by CM1000 but rather its a issue on Comcast side and it is related to the Arris CMTS that needs to be updated with patches to fix the problem. We need to know how many users this is affecting so we can take this data to Comcast push them to make the fix. So more people posting they are having the issue the better for me to pass to our team to pressure comcast.

Count me in on your report. I have the CM1000, Comcast, Gigabit Tier Service. I believe I am on a Cisco CMTS however.
