Random disconnects?

Getting random "attempting to reconnect" for no reason. Happens this alot. Played 3 games, didn't happen. Now I play 1 game, and it happened twice. Doesn't matter the champion or the map. Internet is absolutely fine.

You can see how it happens here. http://www.twitch.tv/n1ce0n3/v/48353972

(not any kind of adv)
