In-game control loss, frequent T3 time out

I have been experiencing severe in-game control loss over the past 4-8 weeks or so (real-time multiplayer games). The only real issue is this real-time response - downloading and uploading do not seem to suffer. I have removed all coaxial splitters from the house, dropped in a 3ghz barrel connector, replaced the modem and router with brand new equipment, tried multiple wall ports and cables, and had an Xfinity tech come to the house. Despite all of this, the in-game control loss has not subsided, and the T-3 timeouts, and event codes 16, 20, 21, 24 for CHAN ID 193 are crippling. The event log below is from my brand new Arris SB8200v3. The router is a brand new GL Flint 2. The machine in use is a Win11 PC that is wired via ethernet. Note that this behavior occurs around the clock - it is not a symptom during peak network use hours.

user_0uwmps Those interruptions would definitely be noticeable when gaming. As a starting point, we’d recommend running through our
Xfinity Internet and WiFi troubleshooting steps. If the issue continues afterward, please let us know what troubleshooting you’ve already tried and whether you’re playing over WiFi or a wired Ethernet connection.

Thank you for the response. I'll try to respond to some of the troubleshooting steps I found:

It's not occurring during local outages.

All coaxial terminations are correctly snug and ethernet ends are secure and clicked in.

As mentioned, this is on brand new equipment (Arris Surfboard SB8200V3 and GI Flint 2).

The Arris and previous Netgear CM1200 run bridge mode by default.

As far as devices experiencing issues - the wife's modern Android mobile phone has loading issues (streaming) while I'm experiencing game control loss (Win 11). This is the only other networking problem I've detected.

The Win 11 PC is hardwired and I have had the same issue with multiple cables. I have tried different coaxial cables at different ports without any difference.

Rather than install multiple games to verify their networking, I have been observing the event log listed here. I think we can agree that covers those bases.

I have scheduled a tech to stop by tomorrow, so we should know more then.
