wireles setup problem

raffigee · 02-15-2006, 07:52 PM

Hi,

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:

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

Code:

iwconfig wlan0 up

SET failed on device wlan0: Invalid argument

and when i do

Code:

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

hi there just to be on the safe side ...
what wlan adapter you are using?

If you are trying to run something like Aircrack, it won't work with ndiswrapper because Windows drivers usually don't support monitor mode.

I'm using the broadcom 54g Max performance.

In a compaq presario R3000 laptop.

I read about ndiswrapper not supporting monitor mode so i downloaded
the linux drives for my adapter form berlioz.de but i have no knowledge at all
in installing a driver.

Can anyone point me to a good step by step tutorial on how to install linux driver.

Thanks any help would be greatly appreciated.

If you are trying to use the bcm43xx drivers, be aware they are still under development, and I don't know that they support monitor mode.

However, installation is pretty straight forward.

You need a 2.6.15 or later kernel properly configured (the README in the bcm43xx tarball tells you the required configuration).

First unpack fwcutter, run make, then run fwcutter against the broadcom Windows .sys file. Then run make installfw.

Next, unpack SoftMAC and run make, then make install (as root)

Finally, unpack bcm43xx and run make, then make install (as root).

That should give you a bcm43xx module that you can load with modprobe and configure with iwconfig.

it did work with fedora core 9 and I think it will work with back track two. I think for backtrek to a friend of mine I did uninstall the module and installed again but I am not sure if they were broadcomm bcm43xx or it was Intel PRO/Wireless 3945ABG but they did work.
