"Connection to Server Timed Out" ERROR:

Okay, it's driving me absolutely nuts!! How do I fix it?

I have already downloaded the server patch, I can connect to the server lists fine, and can join a game, but after 15-25 seconds of playing normally I get the error. I'm on a wireless network card, would that have anything to do with it?

I'm going to try some more...

Thanks in advance for the help (whoever).
