client crashed then my whole wifi adapter faults and resets

a friend and i finished an aram game and friend invited to a new aram game, suddenly the lobby says friend disconected, and friend appears offline in friends list, however the lobby que is still counting down. moments later i am disconnected from chat, then client fails, and attempting to go onto lol.com i realize internet access is disrupted. we both re logged and the same thing happened on friends end, friend lives across the country . very strange what are you guys doing on user end cpu?
