A quick question regarding F*ckPSN

I need help I have tried everything. I just don't understand the exact setup the laptop must be in. If it's wired or wireless. I am able to connect with a wired connection even though my internet is wifi. I can connect the ps3 to the pc with a wired connection and the program works but it times up. I'm guessing since there is no internet active. Yet, when I try wireless i'm clueless.. How the hell do I set up my laptop to work with F*ckpsn? I've looked everywhere and all I get is 'use your pc's dsn number" things. I have done that and nothing!>

Please and thank you :)
