This Also Happened with me, But I don't have Vista, Both my computers were doing it and Me and my friend were playing and we get Dc'd at the same time.

Same thing with me when i play 3.5 its 2 matches before it says "No connection" and when i play 3.41 its about 5 matches before the same thing happens

Maybe the autoupdating makes it lag then DC?

I've got the same problem, but the problem appeard right after I install'd toribash 3,5. I have 3 computers, windows xp on two and vista on one, all of them got the same problem, so I guess its not about the operating system.

Same problem here, I keep getting "Not connected" mid-fight.
And when I'm joining or creating a game, I have to join twice, the first time I always get "Not connected" but the second time always works.

Hrm.
