I have been having a lot of issues with my modem randomly restarting throughout the day. I replaced the modem. Same issue. Also replaced the coaxial cable. The issue still persists. Everything will work perfectly fine for a couple of days and then suddenly no internet, the modem keeps attempting to connect unsuccesfully. I have seen similar issues posted here before, with a tech having to be sent out as the only solution.
Can't see your pics. Since you are a new poster, they likely need to be approved by a Forum Admin. Or you may need to make a minimum number of posts.
You could try hosting them at one of those free third-party pic hosting sites and post the link to them here.
The signal stats are o/k but the error log entries indicate 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 will be able to poll the CMTS to see whether or not everything is in the green zone, see your node / cable plant and modem health, and also see a history plot for the modem. You should get a reply here in your topic. Good luck !
