I generally have the most fun playing DG with my roommate. However, recently we've been having more and more trouble connecting to games.
We are both playing over the same wireless router. When we each play individually, no problems. When we play together we either get knocked out by the NAT facilitator or we get into the game and about 17 seconds in we get booted from the game but not from each other. What is the most likely problem here and what is the most effective solution?
