Hi Xfinity
I am told by Netgear, that these errors in my log file is related to your service and I would like to know how and when you plan on fixing these error messages. Netgear is stating this is an issue on your end and there is nothing with their device they can do to correct it. I am told I should not be seeing Critical/Warning messages in the log file. Contacting support is hopeless.

@user_tt1j4i
Are you actually experiencing any connectivity problems / dropouts / speed problems, or are you just focusing on those error log messages?

What do the modem's signal stats look like ? Try getting them here; http://192.168.100.1 or here http://10.0.0.1
Please copy all of the text in its entirety of the *Downstream Power Levels*, the *SNR's* (Signal to Noise Ratios), and the *Upstream Power Level* numbers and paste them into your next post.
What is the exact make and model number of the modem / gateway device ?
Is this with WiFi connections ?

The signal status values at that snapshot in time were good, but the error log entries indicate that something is going on. Perhaps there is noise ingress into the line(s) / an upstream channel / return path impairment somewhere.
There are other signal stat values that can't be read by the modem. They are the "Upstream Rx Power" (Upstream Receive Power Level), the "Upstream SNR Ch." (Upstream Signal To Noise Ratio), and the "Upstream ICFR" (In Channel Frequency Response). These are as equally important in diagnosing connectivity issues as are the modem's stats.
I'm going to escalate your issue to the Comcast corporate employees (The Digital Care Team) who are available to these boards. They will be able to poll the CMTS (Cable Modem Termination System) to check for any real-time degradation and / or error reports, see your node / cable plant, and modem health, and see whether or not everything is in the green zone. They can also see a history plot for the modem and those upstream receive signal stats.
You should get a reply here in your topic. Good luck !
