Hi William,

A bit inspired by your commands since yesterday I have changed the
desktop file /usr/share/applications/Wifi-up.desktop into this:

[Desktop Entry]
Comment=Bring Wifi up with ifup eth0
Exec=xterm -e "ifdown eth0 ; iwconfig eth0 txpower auto channel 1 ; killall wpa_supplicant ; killall udhcp ; ifup eth0 ; sleep 20"

i.e. inserted your iwconfig/killall sequence before bringing up the
interface; and now it is associating *every* time in my Wifi area at
home (WEP) and in my office (WPA); it even reconnects fine, when I'm
leaving the area and re-enter or when I moved from office to home;
if I have some time I will investigate why this is now working; maybe
there was always some of the wpa_supplicant (the one with the -u flag)
left over; don't know what the -u option means, this option does not
exist in FreeBSD's wpa_supplicant and the FR has no man pages installed;
are they available somewhere in Internet to check?

you can imagine how happy I am;
