issues with logging in/after game as well as during champ select

so i finish a game, and it proceeds to not load the end of game stats, so i press skip waiting for stats, then proceeds to tell me i am "disconnected form pvp" which as far as i new i wasn't, so i close the game and attempt to reopen, it had a connection failure 5 times in a row trying to log in. When i finally was able to login again and get into champion select, the game kicked me out for not selecting a champion, when it was the game itself that would not let me select varus. the connection issues have happened before but the disconnected from pvp as well as it kicking me out of champ select has not. thought i would bring it to your attention. thank you
