Having AD HOC problems with Socom FTB2

I was playing AD HOC on Socom FTB2 last night with a friend and we could join eachothers games, but when we went to start the game, one of us would get a load screen and the others screen would go blank. This only happened for the person joining the others made game. But when we gameshared the demo for Burnout, it worked fine. We do have in car computers in our work vehicles and I think that may be interfering with the connection? If you have any other ideas of what may be causing this or how to fix it, that would be appreciated. Thanks.
