Description rkoberman 2023-01-01 01:15:10 UTC
When running to a remote system with ssh, fairly quickly the interface resets. In many cases, it never recovers. It restarts, associates with the AP, but resets again during DHCP config. This repeats continuously. After a few attempts, the interface does not even associate. This continues and periodically associates without getting an address. Given enough time, it seems to associate in most cases, though I have let it try for over 30 minutes on one occasion.

I have no other available WiFi, so I can't rule out a hardware problem. Problem first noted about a month ago.

No other network use causes this reset.

There was a reference to this same problem in a forum thread almost a year ago. It is in the thread: 
https://forums.freebsd.org/threads/cheap-wireless-usb-adapter-rtl8188eu-rtl8821au-or-something-else.78563/

This was off-topic and was not further discussed. I suppose that this may be a hardware problem.
