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.
Same issue. I just upgraded to gigabit speed and I cant get more than 400mb down. As the day goes on my speed gets less and less until I reboot. I'm on the latest firmware. I've connect the modem direct to my pc using cat6 and I cant get full speed.
I've called comcast and they reposted the provision with no avail.
