I have had the weirdest issue with my network connectivity since upgrading to F37 Silverblue (from F36); my connection drops sporadically every 10 to 45min and only on my end. What I mean by that is, other people can still hear and see me in video calls (e.g., MS Teams, Discord) but from my perspective I have lost connection as if suffering a network outage.
This has been happening for ~2 days and I have been wholly unable to determine what the issue is. I’ve checked logs via “journalctl -fk” and “journalctl -f -u NetworkManager.service” and only observed what looks like a normal interruption of service.
Here’s an example of the ‘outage’ occurring (this is my work VPN connection dropping and reconnecting):
journalctl -f -u NetworkManager.service

I can confirm that this strange ‘disconnect’ issue occurs even when I’m not using my work VPN. Other devices on my network don’t have this issue; wireless or wired, Fedora or Windows, everything else is working as expected.
Any thoughts? I can provide whatever logs would be needed for troubleshooting.
Thanks
