I am running BackTrack 3 on a Dell Inspiron 8600. I am running it on a flash drive. I can't access the internet.

How do I set up the internet on this? I want to be able to access the internet and LAN's on more than one laptop. Can I set it up so that it won't always need to be set up?

I have been trying for a while to get this working but have had no sucess.

Please help
