I've installed Backtrack 5R3 KDE, and I realized that my wireless is not working, but wired is working fine.

Here's the lshw output:

The lspci output might be more appropriate here. –  BatchyX Oct 7 '12 at 14:01
    
@BatchyX - There it is... –  hradecek Oct 7 '12 at 14:58
    
Try finding out what wireless adapter you have. Try following the instructions provided here: cyberciti.biz/faq/linux-find-wireless-driver-chipset (I'm noticing there's a lack of the phrase "wireless" in your lspci output) –  pzkpfw Oct 7 '12 at 17:44
    
@bigbadonk420 - i don't any wireless there... I forgot say, that under Windows, wireless was working... My laptop should have 'Intel’s Centrino Wireless-N 2200 adapter' –  hradecek Oct 8 '12 at 13:07
    
Have you tried googling for a driver? –  pzkpfw Oct 9 '12 at 8:41

Finally I've solved it. I've downloaded appropriate driver from http://intellinuxwireless.org and put it to /lib/firmware...
