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

You said it happens at "random intervals" but can you try to find a pattern to it? Maybe by location or the times that you play?

What programs do you have running at the same time (including any overlays that may be active)?

What kind of connection do you have? Wired or wireless?

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