Networking :: wirelesslan on a thinkpad r50e

hi, i'm new to DSL and i got it so i could work fromany computer as long as i had my USB stick with me(it also helps unfubar computers in my work). I tried it on my laptop, a thinkpad R50e, it booted fine and i can get all my files and stuff but it won't connect. i'm just wondering how i get it working. i honestly can't figure it out.
