Initial Xfinity support chat went about as well as expected, they couldn't detect any issues with the line from their end. They suggested connecting my PC directly to the modem and trying a different ethernet cord. Should I be more direct and point out the issues shown in modem diagnostics?

If issue is still going on or your line connection still looks like your prior post, its either the modem or the line.

Push the issue stating that their power levels are off and there's to many errors/problems on the modem connections screen.
