Thank you for the suggestions. The thing is that everything was working just fine until Xfinity did an upgrade in our area on February 15. Then all the issues started. All the connections and cables are the same as before. Still, they are pointing to the modem as the problem. Attached is the log. Hopefully this provides some help. Thanks again.

Please post a copy and paste of the modems event log page aswell.
I see lots of correctables and un-correctables that should be mostly zeros across all channels.
Be sure there are no coax cable line splitters in the between the modem and ISP service box.
Be sure your using good quality RG6 coax cable up to the modem.
Start with removing any amplifiers, signal attenuators, or splitters from the coax.
From there check the line for kinks, damage, moisture in the line.
Check the connectors for improperly made ends, foil touching the copper coax line, loose connections, bad/old/cheap connectors, or corroded connections. Replace them if you do.
