euh...other packages?

did that. do I have to change anything in /etc/udev/rules.d as well?

after reboot I now see a cabeled network ( wlan0) ( disconnected) and an 
" Auto wlan0 marked as available....

I thougt the wireless card requesting an ip adress and then dropping 
dead might be the problem. Clearly not...
