Thank you for the reply Lainn.

I have a few additional questions. Do you notice any pattern to the disconnections (only when teleporting, only in combat, etc.)?

Do you happen to have another PC you can log into? If you don't experience issues on the second PC, the problem lies with something on your specific PC and not the connection.

If you don't have another PC, are you able to try a different internet connection, like connecting at a friend's house maybe?

Did anything change/update on your PC that coincides with this?

I'd also like to know exactly what you tried if that's not too much trouble. I don't want to miss anything because it was assumed you already tried it.

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