Wifi won't connect

[Fire69]

Ok, tried that, but apparently my wireless keyboard/mouse-combo is not compatible with the RPi (it's on the not-supported list ).
So just connected it straight to my router and connected to ssh like that.
To my surprise, my wifi-settings were already filled in, so there must be a litte bug in the xbmc-version of xbian-config or something.
After connecting everything again at the tv, wifi is working!

Thanks!
