I'm really hoping someone can help me. My husband and I upgraded our internet connection with TWC in North Carolina to the Extreme and they said we could not use our Motorola modem and cisco router. We are now using their UBEE. Ever since the change we have had serious connection issues with XBOX Live. We have two XBOX's, one is hard lined into the UBEE the other is on wi-fi (which we had to go and buy an xbox wi-fi adapter on this new xbox). When we first upgraded both of our NAT's were changed to "STRICT" and then my husband enable UPnP and our NAT's were then changed to "Moderate". We are now having issues being able to play Live (COD:MW3) with a group. One of us is auto signed out of Live or can't join the party/game. As long as I don't play, he is ok to play with others. Can anyone help? PLEASE!!
