WLAN device disabled

[Stephan Schöffel]

hi there,

i'm running kubuntu 7.10 on a hp nx6325 notebook. unfortunately i can't 
activate my wireless connection.

the network settings show the wireless interface as eth1. i is 
configured via dhcp. but the state is "disabled". if i want to change it 
to enabled, it does for about half a second and then switches to 
disabled again.

if i try "sudo ifconfig eth1 up" via console it replies:
SIOCSIFFLAGS: No such file or directory

thanks for any hints.
