[Client] Random disconect even with internet ON

Everyday i'm losing game because i keep getting disconnected during game even tho my internet work just fine. The worse is that i can see what happen in the game for like 20 sec with the message "Trying to reconnect", internet work fine as i'm writing this here i'm in a game where i cant do anything because it tell me i'm dc. I just dont get it its been over a week with this bug. I heard some people with same problem but very few, i dont know how i can determine where the problem come from.
