Actually this is kind of weird but I tried running backtrack r3 and Ubuntu 12.04 live on my laptop but both the times I was not able to switch on my Wireless using the toggle switch, in fact normally in windows it turns on a led on my laptop when wireless is on. But in ubuntu and backtrack this led never glows.

I tried running rfkill list

0: dell-wifi: Wireless LAN
    Soft blocked: no
    Hard blocked: no
1: dell-bluetooth: Bluetooth
    Soft blocked: no
    Hard blocked: no

But still It is not able to detect my home network and not even the led glows.

Details about the wireless card.

Ca you find out the chipset? It should be listed if you run lspci from the linux live session. –  terdon Mar 17 '13 at 18:54
    
Here is what it shows $ lspci | grep Network 02:00.0 Network controller: Broadcom Corporation Device 4365 (rev 01) –  codeomnitrix Mar 17 '13 at 19:13
