As I realized this problem is a common one and several post and toturial a all over the net and this forum going over this, I've tried several and for so many days now but I failed to solve this problem, because of my lack of knowledge in programming in general or backtrack not sure, I would like some help in this pls:

My backtrack 5 r3 installed on MacBook Pro late 2012 on the hard drive separate partition

The outcome of the iwconfig is :

root@bt:~# iwconfig
lo no wireless extensions.

eth0 no wireless extensions.

Currently am trying to follow the steps on this page but I faild as it is shown in the pic I attached
