Hello. AC 9461 on FreeBSD 14.3/amd64 (no patches applied this time). When I go to a particular customer, I have troubles connecting to the WiFi network: the signal is good, the phone sitting next to my laptop associates immediately and is stable, but my laptop usually stays offline. I have to run "service netif restart" several times and it will sometimes work. Rebooting is more likely to solve, but it might take three or four attempts. When it finally associates, if it doesn't disconnect immediately, I can work all day without troubles (leaving speed matters aside).

I tried looking up those "fail to flush all tx fifo queues Q 5" and "Queue 5 is active on fifo 3 and stuck for 10000 ms. SW [2, 3] HW [2, 3] FH TRB=0x080305001" in the bug reports, but I don't think any matches. Is there anything I can do? Anything I should report? bye & Thanks av.
