My AP is using 2417 MHz ch 2, none of the nearby Aps are using it. The
second strongest is using 2437 MHz ch 6. That's with the Pi5 within
three feet of my AP. At the moment Wifi won't connect at all, though
both my cellphone and a second computer farther away connect successfully.

Another puzzle is that wavemon reports 5825 MHz ch 165 after the connect
process fails. The targeted access point uses only 2417, so it's as if 
an unprompted search has started. Meanwhile my cellphone has no trouble
connecting to the AP, near or far. 

There are 15 APs within range, most reporting ESS including mine. Anybody
know what ESS signifies?

Thanks for writing,
