The wifi dropout has repeated three or four times since the initial case.
Usually it dropped after an hour or so of uptime and couldn't reconnect
on its own, the Pi had to be rebooted. Haven't seen anything more about
rfkill after the first incident.

I put a voltmeter on the GPIO power pins, it looks steady at 5.09-5.10 volts.
The meter isn't what I'd call a precision unit, but it's likely within 50 mV,
so the voltage isn't obviously wrong.

Just a few minutes ago the WiFi dropped, then came back up on its own a
couple or three minutes later. Wasn't watching the voltmeter, unfortunately.
I'll keep an eye peeled more carefully, perhaps it can be caught in the act.

Thanks for writing,
