Multiple computers can't play from same network Titanfall PC

Hi,

My roommates and I (four of us) have all purchased separate licenses of Titanfall and installed it on our computers. We played a ton together, as a team (the intent of purchasing the game), for quite a while up until a few months ago when our schedules began conflicting.

Both of these threads have instructions on disabling uPnP on the router and the host machine. This was done, but did not solve the problem. The only other solution offered on the threads, not by an EA representative, was to ask for a refund as the issue is the intent of EA and will not be solved. Can you validate these claims? If it's not the way the game was to be hosted, what is a viable solution where multiple computers can play from the same network? I'd hate to be living in a dorm, as you're pretty much shutting out the entire college demographic and losing a ton of money if this is the case.
