Network Issue!

[Lysserd]

I can't play this game with my room mate. We both love this game, and we'd both love to be able to play at the same time. But Warframe simply won't allow it. Now, we can both play just fine in separate games, but if we both try to go into the same game then it locks out his computer. If he's able to connect at all, it will be for a few minutes until he de-synchs with his character. He'll think he's moving around, but he's actually just standing there until someone completes the mission.

Has anyone else run into this, using two comps on the same network issues? Is there a known solution?
