Ok this is really frustrating at this point. I keep having this issue since 3.5. I have never ever had any disconnects problem and I play since day 1 of ARR early access. Tried literally everything. Reinstalling windows and game itself. Using VPN (wtfast), setting different DNS, calling ISP and tracert. Funny thing is - I have no lost packets at all. The game just decides to DC randomly, usually it happens when I zone in to the new place (like when 24 man ends and I spawn back in housing area, or when I enter a dungeon). It's beyond frustrating and it makes me wonder how on earth this is still not fixed. It's clearly something on SE end and else, there wouldn't be so many people with similiar issue.
