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.
I have been conveying that to Xfinity Comcast since last year and it falls on to deaf ears...................
So I have a cm1000 modem also my problem is vudu and apple tv both hang on trying to load movies.
Similar issue here. I have a CM600 that is capable of gigabit speed. I recently switched from Blast to extreme 150. I'm getting between 80-90Mbps most of the time. The CM600 has the latest firmware. After troubleshooting 4 times with their tech support I asked them to send someone to my house. They said everything looked good but they changed out the line that goes from the house to the pedestal box. I still get the same speed. I have an extra CM600 and a SB modem, don't recall model right now. I'm thinking of swapping out the cm for the other cm and testing. This is really aggravating.
I'm running Comcast's gigabit service as well as a CM1000 on the latest firmware and not reaching anywhere near my speeds I should be as well.
Just to add my voice to the frustration.

So I have the CM1000 with Comcast's gigabit service. Have never actually received gigabit speeds, and average speed when connected directly to the modem is about 400-500 Mbps. Great speed, sure, but nowhere near the gigabit speed I'm paying for. Highest I've ever seen is about 700 Mbps, and that is for very brief periods of time. For what it's worth, our neighborhood and house are brand new. Comcast has been useless thus far in trying to resolve this. They keep blaming the modem and say I need to use their equipment...event though the CM1000 is certified by their own damn company.
EDIT: I'm trying to post screenshots of the modem data, but nothing I'm doing is working. Tried hosting them externally, attaching them here, and tried clicking the Photos button to add them. Nothing works.
