I am having the same issue, sent in a help ticket with customer support, still no reply. I am getting very frustrated. I can't complete a single dungeon all the way through without lagging/R=0 every 30-90 seconds, and then error 90000 disconnecting me, which then prohibits me from joining back up into the instance I was just in, having to start ALL OVER again and again and again and again and again. Can SE please update us on the current situation with this issue? Has it even been addressed? ISP running great, modem and router the same. What is going on?
