I have a new[ish] Pi Zero 2W running in a building close to our house
(close means about 30 yards away).  When I installed it I configured
one of the possible WiFi SSIDs with rpi-imager, then after installing
I added the other possible SSID (using nmcli I think).

It has run quite happily for a few days but as of yesterday afternoon
shows no sign of being connected.

I have tried restarting it, no effect.  I have checked both of the
routers it might connect to and they're both running and haven't
moved. I've even moved one of them into what is effectively line of
sight to the Zero 2W.  Still no connection.

What might be wrong and what can I do to get it to connect?
