The title says it all. I was wondering if anyone can help me get my ps3 online with a 3g mobile broadband card. The carrier is AT&T and I've already tried Internet Connection Sharing and when i run a connection test i get the error "The attempt to obtain an I.P. address timed out." I've checked many sites for this question, but all the sites say what I've already tried and nothing is working... Plz Help Me! I really want to play some PS3 online.
