That's what I'm doing now! :P

Alright. I'm attaching these. The signal strength is pretty weak despite my
being somewhat close to the WAP. (Which is, FWIW, a node in a small Unifi
zero- handoff network.) That said, I manage solid connection with this laptop
in the same spot running Linux, and with MacBooks.

I'll happily supply more diagnostic information, as needed.

Same here running Linux. It's only problematic with FreeBSD driving the
hardware. I'd very much like FreeBSD to be driving this unproblematically.

This was briefly hopeful. I set that in rc.conf and rebooted, and I got a
quick, solid connection. But then through several subsequent reboots my wifi
light is flashing and connectivity is sporadic at best, with the same
messages piling into the console.
