Cannot connect to wireless (intel pro 2915abg) in backtrack 4 r2

I am on an IBM thinkpad t43 using backtrack 4 r2. Wireless works in windows (/dev/sda1), openSUSE 11.3 (/dev/sda2), but not backtrack (sda3)

#cat /proc/pci

I previously tried to manually connect to my open wifi router sitting right next to me using these commands (keep in mind this laptop is triple booted and wifi works in winXP, and openSUSE 11.3):

#iwlist eth1 scan (it did not find anything)
#iwconfig eth1 essid buttars
#dhclient wlan0
I used to get errors while booting that showed up in dmesg as something like "ipw2200 module failed error -2". Searching the forums I found this command:

#cp -v /lib/firmware-2.6.34/ipw* /lib/firmware/
That cleared up the errors and from then on I had eth1 in ifconfig.

Can anyone point me in the right direction?

I did above.

Anyway, I took it to school today, and scanned for our wireless. It actually found it and was able to connect. I didn't do anything from the time I ran that copy command and connected at school except turn it off for the night. So Im amusing the copy command worked and it just needed a hard boot. That or a good nights rest...which is what I need right about now.

another thing may be that your intel wireless drivers may be locked to the wrong channel range and your school network just happened to be in that range, it's a common issue with intel wireless cards, i can't remember the URL but a quick google should find it


backtrack4, thinkpad, wireless
