Riot pls this game is fun but i need help.

Ok so I keep on trying to play league and it will work one time and then stop working. So I login, pick the game mode I want to play (even practice tool), find a game, pick my champ, the game starts, I don't connect and I am sent to the reconnection page. So I try and reconnect to the game and nothing happens... I try till the game is over by a remake vote then I get sent back to the end of game page, and probably get reported. I have tried restarting the client, uninstalling the client, the hextech repair tool, restarting my computer, turning off my computer, I have sent a complaint already to riot, but I was wondering if anyone here can help me.
