The card is fine and it'll work with WPA/TKIP.
Go to your router settings first of all and set WPA/TKIP - B/G mode.
Don't use mixed mode or WPA/WPA2 PSK. It is important that you set WPA/TKIP.
Then go to your User-startup. You'll find a line:
C:WirelessManager prism2.device
Put a semi-colon in front of it and save. Make sure you have CardPatch and CardReset installed in your Startup-sequence.
Now, reboot. After loading the WB open CLI and type:
C:WirelessManager prism2.device
We'll see what happens. If you have set the router right it should associate with the router.
What's your setup? What's the turbo board?
