I’m having exactly this issue. Up until yesterday I never experienced any disconnects out of the ordinary. Momentarily I thought the issue was network related, but after having reset my modem/router, reinstalled and updated firmware, opened up ports through portforward.com etc etc, I can’t do anything but conclude the issue is from your side.
It’s gotten so bad I disconnect sometimes anywhere between 1-4 minutes, making it unbearable and impossible to play. I am an avid WvW player, I participated in testing for the newest WvW map and even there I had no such issue whatsoever. It came as quite a shock to see this thread with hundreds of replies mentioning the same issue and the way I see it, even after months passed and players having reported in on this issue there has been no offer yet alone a mention of a solution.
Just what is going on?
