backtrack4 ipw2100 module not being loaded for intel pro wireless b lan

rfelsburg — Tue, 19 Apr 2011 02:10:35 -0400

I can't get my wireless card to be used/assigned under backtrack4. I know it works I've used it on other backtrack installs.

Everything seems to point to backtrack recognizing/seeing it, but it's not recognizing the eth1/wlan0/ath0 interface when I try to set it up.

ThoughtS?

Found the following code in dmesg. It appears that the firmware module isn't being loaded.

Connecting to a wireless network which uses wpa-psk encryption using Backtrack distro

rfelsburg — Tue, 19 Apr 2011 00:11:28 -0400

PROBLEM

I was having a problem setting up wpa_supplicant on backtrack4.

My wireless point uses wpa-psk.

In /etc/network/interfaces:


root@bt:/usr/bin# cat /etc/network/interfaces
auto lo
iface lo inet loopback

#auto eth0
#iface eth0 inet dhcp

auto eth1
iface eth1 inet dhcp
pre-up wpa_supplicant -B -Dwext -i eth1 -c /etc/wpa_supplicant/wpa_supplicant.conf # you might change these bold parameters to suit your wireless card and interface.
post-down killall -q wpa_supplicant

#auto eth2
#iface eth2 inet dhcp
#
#auto ath0
#iface ath0 inet dhcp
#
#auto wlan0
#iface wlan0 inet dhcp

Everything I read said to use wpa_passphrase like below, and delete the commented lines:


root@bt:/usr/bin# wpa_passphrase My_ssid My_ssid_key
network={
        ssid="My_ssid"
        psk=e8a2c6fb04c3537ec1ea7c027b78f96fba46bc5497503dfe0aa2510844e82ce9
}

however this failed miserably with my setup.

Ideas?
