crabiorc: it looks like you're most of the way there if you have the Windows driver loaded into ndiswrapper and ndisgtk (the graphical "Windows Wireless Drivers" utility you're using--it's just a graphical frontend to ndiswrapper) says the hardware is present. This means you installed the right Windows driver for your device.
I'm guessing that either the ndiswrapper module is simply not loaded, or it can't claim the card because another driver is trying to. Please run these commands and post the output; hopefully these will put ndiswrapper in control:
By this point, hopefully your wireless card will be working. If it's not, the command output should help figure out why.
sudo rmmod wl
sudo rmmod ssb
sudo rmmod b43
sudo rmmod ndiswrapper
sudo modprobe ndiswrapper
sudo iwlist scan
dmesg | grep -e ndis -e wlan
lshw -C Network
Also, note that some of the commands above may have no output, and that some of them may produce errors. That's alright; just proceed to the next command.
