game disconnects once every game

SO this started happening one or two weeks ago. I get disconnected from the game exactly ONCE every game for about 10 seconds. At first, I thought it was my connection, but then I started to think that getting disconnected exactly once per game doesn't make sense. So I tried other things such as playing other games or just surfing the internet. SO it turned out it wasn't my connection. EVERYTHING else worked fine even at the moment when league was disconnected. Now, I tried reinstalling the game, of course rebooting the computer, rebooting router and all. I really think it's the league client's problem.

Anyone having the same problem? or is it just me? Does anyone have ideas of how to fix this?
