Dcing 24/7

So, this happened yesterday while i was playing league, it was around 9/10 pm and all of a sudden an error pops up saying that it's attempting to reconnect, it was strange because my internet was just fine, 10mb/s internet and i'm using a cable not a wireless just letting you know, whenever i tried to reconnect to the game it allows me to play for a couple of seconds/minutes and then my champ stops walking and i can't do anything, i lost 1 game because of that and that also happened today. Same thing, error message, playing for a few minutes/seconds, disconnect. I tried every method i could possibly think of. Restart,initiate full repair,hexteck repair tool,restarting the computer,closing the client, reinstalling the whole game. And yet it still pops up, i seriously don't know what to do, if anyone could help me that would be amazing, Thanks!
