Something on your web: http://people.redhat.com/dcbw/airo-wpa/ and a "recent" (4 years) version at http://svn.gna.org/viewcvs/airo-wpa/branches/kernel/ It looks ugly (wpa_enabled module parameter) but seems to work with WPA-PSK. Do you remember what's the problem with switching between WPA and WEP? I'm going to remove the wpa_enabled module parameter and allow run-time switching between WPA and WEP to see what breaks. -- Ondrej Zary
