Hopefully some of you might be able to help me out. I have a 360 upstairs and one downstairs. Both going through my router and both have different gamertag accounts. 1 for me and 1 for the misses. When we play Uno, we can both create our own lobbies and enjoy online gaming with other live members, we can also play each other in a private lobby but for some reason we cannot both join someone else's online game. 1 of us can join in but the other keeps getting failure to connect messages. Is it not possible to have both gamers in the same game going through 1 router and 1 phone line? Advice very much appreciated.
