This seems to have started on Wednesday night, maybe Thursday. Thought it was my cablemodem, so I reset that, and it seemed to be fine for a while. But it got extremely worse on Friday night. Makes the game totally unplayable. I'll be in game (if I can get logged in at all), and doing anything, and poof. Back to login prompt. I could be in the middle of a conversation with an NPC and it'll send me back. Or in the middle of a jump.
Most times I know it's going to kick me out to login because I'll try to interact with something, and I can't pick up things. Or I can run right up to an enemy and they ignore me.
I've done all the requesite network connectivity checks. My pings are low, in the teens. I run ping plotter or a Ping -t to my firewall at work. No dropped packets. Everything else in the entire house is working fine.
I have a ticket open, but I really think it's a capacity issue, or an issue with ESO's bandwidth.
