Bringing the card up by hand
1. Type: ndiswrapper -i /mnt/hda1/Wireless/<name-of-driver-file.inf>
2. Type: modprobe ndiswrapper
3. Type: iwconfig wlan0 essid any
4. Type: iwconfig wlan0 channel 11
5. Type: ifconfig wlan0 up
6. Type: pump -i wlan0

all goes well until... the 3rd step and 4th which gives the error

error for wireless request "set esside" (8b1a):
