I've been at college for three weeks and just now the cable connection started working so i don't have to rely on horrible wireless... but I've been wanting to play battlefield 2142 but can't connect to a game. I get on the lobby server fine, but when i try joining a game it says I have network connection issues... is this a college firewall issue that I can't fix, or is there some network configurating i can do on my comp to fix it?
