RECONNECT

Ever since i got accepted into the league client alpha, my pc has not been able to play games on the new client consistantly. 99% of the time when i go to play a game, right after champ select itll say reconnect and will not let me get into the game, but the moment i switch to the old client, everything works just fine. is there anything that anyone has done to fix these things. ive deleted hamachi, plays.tv, and even avg, but cannot find a way around this stupid bug that i am getting. please help!!!
