All good. Is it the same with a direct connection to the 8200 cable modem (no router in the mix) ?

O/k. Even though the signal stats looked o/k at that snapshot in time, the error log entries confirm that something is going on. Perhaps there is noise ingress into the line(s) somewhere.
There are other signal stat figures 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 that are available to these boards. They can check the CMTS (Cable Modem Termination System) 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 poll for those upstream receive signal stats.
You should get a reply here in your topic. Good luck !

Hi @Lunanestor,
Thanks for posting to the Xfinity Forum and sharing the details of your experience. I agree with @EG. I think there may be a bigger issue on your line/ at the node. I'd be happy to investigate further and work with you to help get this resolved. Can you send me a private message with your first and last name and service address? To send me a private message, click on "ComcastChe" and then click send a message.
