We have the same issue! I did some research on this and found what I believe is the issue. The ip address of the router is what is being identified as one computer. Thus if 2 people are trying to connect to the same game then it would only load once (because you only have one router). I have heard rumors at work that setting up a vpn may resolve this issue. That being said you would probably have terrible lag. In addition it may violate ea's terms of service (honestly have no idea). I want this fixed as soon as possible and I am willing to test for you! This game is the perfect college dorm type game to play with friends. My theory is only one person would connect to the server if they were all connected to the same router. If we are able to get an extra router and set up a slave router my concern is that it will still only push one ip address out of the modem. Let me know if you have any ideas/temporary fixes! Thank you guys!
