I don't know. I just noticed that if I used only one of them, it
didn't work (IIRC, ifconfig ... up ... fails without the first
iwconfig, and ifconfig ... up ... resets iwconfig settings,
somethink like that).

No, because I stop wicd first to avoid bad interactions between wicd
(which can do things automatically) and this script: it is bad to have
2 different active methods to do a wifi connection at the same time.
