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

Do you recall anything changing on your PC or Home network that coincides with this?

It looks like the route you are taking is a bit unstable. You are dropping packets in a few places and the response time varies. Although, I can't tell for certain whether this is causing the disconnections.

There are a few things I'd like to suggest just to strengthen your home network connection:

1) 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.

2) Make sure your anti-virus/firewall has the appropriate exceptions for Final Fantasy XIV (you can temporarily disable them while you try to connect as well).

3) Make sure to use a wired Ethernet connection as opposed to wireless

4) Check the following Port Ranges on your router/modem to ensure that they have been opened:
▼TCP
54992 through 54994,
55006 through 55007,
55021 through 55040
Your ISP can open these ports for you.

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