:/ Did you try setting up the port? Your firewall is most likely blocking the Punkbuster packets from doing their job which is most likely the reason this isn't working.
First, I'd like you to try (warning direct download link)
this program, it's a punkbuster program, after running it there is a test PB button or something of the sort, click it and make sure PnkBstrA.exe and PnkBstrB.exe are working. If they're not you'll need to set up a port, which if you want to do that, I'll need to know what brand (2wire, cisco, belkin, etc.) your wireless router is.
Also, sorry this is taking quite a bit of time, I've actually only ever played one online PC game, and it's not even associated with punkbuster, yet.
