When i first got here in college I was able to connect to bnet fine and play games... then I started having problems where I could join games but then as soon as the game would start, things would lag amazingly. Now ive gotten to the point where i can log on battle.net fine without any lag, i get 1 green, but whenever trying to join a game, it will say "unable to join game"... Does anyone know a way to fix this issue? Or what the problem may be?
