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

The ping test you did seems very unstable. Is it possible to provide a trace route as well?

If you haven't tried them already, I'd suggest doing some of the following troubleshooting:

1) If you are connecting to your router using a wireless connection, try connecting using an Ethernet cable.

2) Try a clean boot. Simply open the task manager and select the 'Start up' tab. Disable everything here and restart the PC. This will make sure that no background processes are interfering with the game.

3) The game will use the Internet Explorer web browser to connect to the internet. Open Internet Explorer, then open the "Tools" setting, go to "Internet Options" and adjust the following settings:
- Under the "General" tab, please delete ALL browser history.
- Under the "Security" tab, please move the slider to the lowest possible settings or no higher than "Medium"
- Under the "Privacy" tab, click “Advanced” and select ‘Accept’ under both First Party and Third Party Cookies.
- Under the "Advanced" tab, please make sure that "Allow software to run or install even if signature is invalid" is CHECKED.
- Make sure that all SSL and TLS (EXCEPT SSL 3.0) are CHECKED. [SSL 3.0 should be UNCHECKED]
- Hit "Apply" to save the settings, and then "OK, to close the Internet Options menu.

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