Extremely High Ping While Online Gaming

I use an Xfinity modem

Thanks for confirming @user_y6jikd. Does this usually happen during peak hours? What troubleshooting steps have you tried so far? Was the technician able to locate any issues when they came out?

This happens at all hours. I've tried the following: different ethernet cables (over 10), different devices, factory reset devices, restarted modem, flushed DNS on PC, tightened/loosened the coax cable, restarted devices, completely reset our network to defaults, reinstalled the games on different drives, tried bridge mode with a router, probably more I can't recall. When the technician came it was due to the ping issues and us having no internet. The problem was the coax cable so he put in a new line and left swiftly but couldn't ask about the ping problems That was the only issue he observed on his visit.

Since you’ve already ruled out the ethernet, cables, DNS, and bridge mode, I'd like to take a closer look @user_y6jikd.
