Reconnection fail

Ok now, seriously riot this is getting annoying

For some reason i cant connect to a game, after champion select it says that it failed to reconnect to the game and that the game has crashed, 2 games in row this happened now and i have to wait 20 minutes before i cant start a match, in 5 games. This happened before but it fixed it after 1-2 weeks. What is the point of having PvP in your game if u cant handle 10 players in one map without someone laging? I am playing on a Mac, even though i do it should be totally fine but this bug is getting old. Please fix this
