[SOLVED] Network Connection Failed WIFI/WPA2

[Chakky]

Hi Guys,

I have a problem with the my WiFi network.

My network is protects with password that includes special characters like &%$.

If I changed the settings per SSH and after restart the service I get following msg:

Code:

ifdown: interface wlan0 not configured
Error for wireless request "Set Power Management" (8B2C) :
    SET failed on device wlan0 ; Function not implemented.
wpa_supplicant: WARNING: plaintext or ascii WPA key has 3 characters,
wpa_supplicant: it must have between 8 and 63 to be valid.
wpa_supplicant: If the WPA key is a 256-bit hexadecimal key, it must have
wpa_supplicant: exactly 64 characters.

DHCPDISCOVER on wlan0 to 255.255.255.255 port 67 interval 7

I think, I must escaped the special characters. On other systems like Raspbmc or raspbian it is work.

Can anybody help me?
