Around early this year (I cannot remember), I've been experiencing a ton of disconnection issues. Even when I have perfect internet connection I would lose connection from the server and get kicked to the main menu. I would be hanging out with my friends or in a Duty when all of a sudden, I get kicked from the server. Even during Endwalker's Early Access release I would be minding my own business and next thing I know, I'm back at the main menu.

I think that the player cap on the servers (I'm on Omega) being exceeded may be the cause of my disconnection problems but most of the time it's only me that has this problem. Even on a perfect day, I just get kicked off. It's even worse when I'm doing a Trust Duty, I get to the final boss and come close to killing it when all of a sudden, poof! I'm kicked. It's so annoying
