I'm trying to setup my wireless network from a back-track live CD and i'm having problems.

I installed the driver using ndiswrapper.

I did ndiswrapper -m

I did depmod -a

I did modprobe ndiswrapper

Here's my code:

root@slax#  airodump wlan0 out 0
  ioctl(SCIOSIWMODE) failed: Invalid argument

   ARP linktype is set to 1 (Ethernet) - expected ARPHRD_IEEE80211 or ARPHRD_IEEE802111_PRISM. Make sure RFMON is enabled: run 'ifconfig wlan0 up': 'iwconfig wlan0 mode Monitor channel <#>'

when i do

iwconfig wlan0 up

SET failed on device wlan0: Invalid argument
and when i do

airmon.sh start wlan0
   Interface     Chipset     Driver
     wlan0        Unknown     ndiswrapper (MONITOR MODE NOT SUPPORTED
Can anybody find what's causing my problem ?

Thanks in advance
