WLAN config get lost ESSID and KEY

Hi

Using pres Home IP DNS Gateway will be stored but WLAN Key and ESSID not.

So after each reboot it must be redefined .
Knows someone a solution ??

Bye

Seems that I found the problem .
Edit /etc/network/interfaces
and insert wireless-essid ,wireless-key
Example:

face eth0 inet static
address 192.168.0.6
netmask 255.255.255.0
network 192.168.0.0
broadcast 192.168.0.255
gateway 192.168.0.1
wireless-essid myhome
wireless-key AFFEAFFEE

Would be nice if someone can verify or acknowledge the solution
