*Ping* on that again. I send you the requested information two days ago:


Sorry, this is /sys/class/net/wlan0/device/net (forgot the net). But 
here we go, it's really quite simple:

thor at pike:~> ls -la /sys/class/net/wlan0/device/net
total 0
drwxr-xr-x 4 root root 0 Mar 17 17:55 .
drwxr-xr-x 4 root root 0 Mar 17 17:55 ..
drwxr-xr-x 6 root root 0 Mar 17 17:51 wifi0
drwxr-xr-x 6 root root 0 Mar 17 17:55 wlan0

Greetings,
	Thomas
