I read the previous posts but i couldn't find the solution for my problem

When I open Limewire,
Like everyone else, it says "enabling open information sharing" at the top
so i change the firewall settings, to gnutella and "your test worked" page and stuff....
but since im using a wireless router, this computer is connected straight to the router (another computer is wirelessly connected), i think it's doing something there to prevent my limewire from working??
any solutions?
