Good afternoon and thank you for posting on the Final Fantasy XIV Technical Support Forums.

When did this first start happening? Did anything change/update on your PC that coincides with this?

You mention that you disconnect within 2 minutes of logging in, have you tried this on only one character, or does it happen with multiple characters? What location are these characters in?

Can you list everything you've tried to alleviate the issue?

Are you using a wired or wireless connection? The information you provided above suggests both.

We hope we can be of assistance in helping you enjoy the exciting world of Final Fantasy XIV!
