GETTING DISCONNECTED INGAME

Its been already 5 days ,that i get disconnected every fucking game and i have reported this bug and still nothing . I think its not my network problem i have talk to my internet support and he said that everything is okay u have good signal,and i think the problem is with the client because when i get disconnected from game i keep my teamspeak opened and twitch and they are runing fine . I WANT FROM THEM TO LOOK AT AND FIX THIS PROBLEM
