My WAN connection would just randomly start losing packets and would not recover, not full disconnect just lots of retries. Didn’t impact LAN just WAN. Unplugged the cable or disabling then re-enabling the interface would fix it for a coupe of days to a week then it would come back.
Time consuming to diagnose as switching cables, ports, etc would require waiting days to see if it fixed it.
Eventually had the ISP come out and swap the fiber media converter and fiber integrity. But again it came back.
After several weeks I stumbled on a FreeBDS bug that was exactly my issue…I was running OpnSense and my gateway had I225s. Applied the scripts and it worked.
