iwconfig not working on feisty

Binary package hint: wireless-tools

My wireless card is an rtl8180 card. Modules are loaded. Knetworkmanager was not able to configure my wlan0 interface, I didn't know why (network was detected). I tried manually. The essid is not properly configured. I tried and found a method. Anyway, it's a bug :-)

Look at the config order and the iwconfig output. First time and second time. Second time worked :-) (actual essid of my network is WLAN_D9).

gabi@Ganimedes:~$ sudo iwconfig wlan0 essid "WLAN_D9" key s:Z0013495DB3D9
