It turns out that moving the Pi5 within three feet the access point
restores normal WiFi operation. Signal quality reported by wavemon
went from 90% to 100% and the WiFi connected automatically in parallel
to a wired connection. However,  neighbor's APs using the 2.4GHz band 
appear with 67-76% signal quality. If I were to move the Pi5 back to
its original location, its signal strength at the AP would be much lower.
 
It's difficult to improve the Pi5's antenna, but my AP has an
SMA connector. Does anybody have experience with directional
antennas?
 
At the moment, the Pi5 is showing 5.05 volts at the GPIO header.
I think that's slightly lower than I saw previously when the Pi5
was in the troublesome location. The PSU doesn't seem the prime suspect. 

Thanks for reading, and any suggestions.
