Intermittent Modem Connection - no power on 21 of 32 channels
Working great - checked modem admin screen (Netgear CM3000) power on all channels 3.1 - 4.1 ish SNR 43 ish. Starting around 5:30 PM EST I started seeing the Internet drop off and on. Checked modem and saw 10 - 100's of thousands or uncorrectable erros on channels 12 and higher. Rebooted modem a few times - same thing every time. Called Support. CSR sent a signal down the line which she said should fix things and do a reprovision.
After the process was complete (20 minutes) I now no longer had any power or SNR on channels 12 and higher. For the first 11 channels, channels 2,3, and 4 bounce between being locked with power of 3.0 and SNR of 43 ish then 5 - 10 minutes later show unlocked with no power or SNR. Repeats reguarly. To be clear when the issue started and throughout several reboots I had power on all 32 channels.
CSR telling me that Xfinity cannot configure the modem - um, yes, they can as they are the only ones that can provision it and upgrade firmware.
Bypassed all internal wiring with new coax from block on house to modem - no change.
CSR won't check neighbors lines to see if a wider area issue. Internet is working, so most people would not know there is an issue - I only knew as I was here at the time of the drops and my modem's downstream light blinks when there is an issue.
While I expect that they will find an issue likely at the node as no storms or winds today that would be impacting the lines, I wonder if it not showing channels above 11 having power/SNR could be due to a provissioning issue.
Tech won't be out until Thursday afternoon.
In almost 20 years this is the first real issue I have had with Xfinity Internet other than when a storm/accident takes down a line. Not happy with the support I am receiving and the lack of Xfinity to the power on each channel. 800 Mbps plan - actually see 930 Mbps on speed test very consitantly.
Pics attached showing issue of bouncing between locked/unlocked channels 2/3/4
Thoughts?

Trying to post again without the screenshots on last nights post as post said "private" in purple letters - no idea why.
And update - as of this morning, seeing T4 and T3 errors being logged just about every minute. When it is up I am seeing under 50 Mbps download - getting 176 Mbps upload.
