Resetting the router of course won't help if several people have the problem and it''s only at this game.
Even now I have similar problems, however once I'm in the game it works fine. It takes about 10 minutes to be able to login in such a way that everything works. Also this forum is very slow. But it's already much better as yesterday. I just need to remember that when I have a match I should login at least 15 minutes before the game starts.
