I only try to use wpa_supplicant if/when I need to deal with an AP
configured to use WPA.

At home, it's simple WEP; I can't get wpa_supplicant to even associate.

Association was not my problem: getting a DHCP lease was.

The only veariable (other than changes in the software over time) was
the use of different APs.

And for whatever it's worth, when Julian was doing a vimage demo using
my laptop last night (BAFUG -- www.bafug.org), the iwi0 NIC of the
laptop both associated with and got a DHCP lease from my 3rd AP (the
little portable one -- ZIO is its brand name).  That was running head at
r199220M.  (Though in that case, since I set the AP up for the whole
meeting to use, I did not use WEP -- I left the AP wide open.)
