ok you do not say if you have installed ur .inf file from windows.. i have the card working on exactly the same kit this is what u do...
as root type
if you have successfully installed your windows inf file it will say blah present
if this is not the case do
ndiswrapper -i /path to inf file
and try again
if it is the case do
then modprobe ndiswrapper
then use iwconfig to set up to meet your settings
then type ifconfig wlan0 up
...once this is done go to control centre and network
click on new network connection - go to lan and the option wlan0 should appear if not try reboot.
once you go through this...finished the job after putting in details..at the beginning it should give you an auto-ip option (DHCP) just check this in the modify network connections in the network control panel...once you have made all this sure then you can go to monitor connections to see if you get a complete connection...if this doesnt work at first always try a reboot and play around a little with settings
in my experience wep is tricky to get working...i have a non wep wirelessnetwork but i allow the wifi cards access on the router
hope this helps if not mail me
