How come when i play Xbox live, anytime i am a party leader no one in my party gets put into a game with me?

I have perfect connection and i never have any problems when I play alone|||First off, Which game is this? It probably is because your connection is not suitable, the connection problems are only occurring because you are either using a router or just have a slow connection. It's nothing to be upset about, you can still have your friends host games and join through them. Have you always had this problem?
