Wierd bug happening very randomly, not once but several times during a game!!

Ok so i get this bug where all of the sudden i cant see my dmg on minions, all champs but me gets invisible on map, and i have to reconnect to make it stop.. then some games it comes, and some it does not. Everything can seem fine, till i cant see if i hit minions or, my life is just dropping because a player is killing me but i cant see it, the game doesnt even register that im dying, so when i die i just stand still in lane, and game still bugged. I have a roommate we have the same net, the issue is only with me, when he has cable in net, he has no problem, when i have cable in net, i have no problem. but whenever we are using wireless connection, we are having the same kind of bug.

Pls fix it for us
