Hi first start networking
then start wicd form K-menu|internet|wicdCode:/etc/init.d/networking start
then you can open wicd from link next to clock.
Once you got wicd working you want to log off. (ctrl+alt+del)
You want to do this, cause all programs that are open when you log off will start every time when you start BT4
I think that BT4 will recognize that wlan device as wlan0 then you can try toCode:ifconfig wlan0 up
