After this I run the Wireless Assistant 0.5.5 Application, and voila.. I can find some wireless networks...but I cannot connect to them, I mean, I click on one..and no matter if I enter my network's key it says all the time 'Connection Failed'. I don't know if whatever I told ya above is actually required but I thought to write the whole story once.
Open a console and type:
Hit enter then type
Your Intel® PRO/Wireless 3945ABG can now be found at eth1
For Those of you that have backtrack2 installed on your hdd. To save typing all that in every time you restart.
Open a console and type
alias 3945="cd /usr/src/drivers/ipw3945-1.2.0"
now all you have to do to enable your Intel® PRO/Wireless 3945ABG is type
replace 3945 with whatever keyword you want as I only used it as an example
