SOLVED.

The root of the problem was that wpa_supplicant.conf moved from
/etc/wpa_supplicant.conf to /etc/wpa_supplicant/wpa_supplicant.conf.
My laptop that was connecting to the network didn't have
/etc/wpa_supplicant/wpa_supplicant.conf at all so the program must
have used /etc/wpa_supplicant.conf instead.  The desktop that wasn't
connecting to the network had an example file in
/etc/wpa_supplicant/wpa_supplicant.conf so it wasn't reverting to the
old config location.  Nasty.
