I can Party with one of my friends, but anytime we have other people in the party in which I am a part of every one but myself and the original friend I was partied with gets kicked from the game when searching for a lobby ~175ms. We are able to stay in the xbox live party just not in the in game party. My nat type is open and I just bought a Netgear N600 router. Grande Communications is my internet service provider. Any ideas as to what i can try to fix this issue?
