Thank you for the reply Xeraser.

I'm actually not sure where the EU Data Center is located (the exact location isn't publicly available) so I can't say for certain if you are doing a speed test to the right location. In regards to latency, this is usually the result of congestion on the way to the server. Exactly where that congestion is occurring I can't tell for certain unless we had an accurate trace route.

We can, however, make sure that there is nothing interfering from within your home network.

First, I'd suggest sticking with a wired connection. I understand that it's inconvenient but a wired connection will be more stable overall. In addition to this, try some of the following:

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.
- Right-Click on the FFXIV launcher icon and select "Properties"
- Go to the "Compatibility" tab, and change the compatibility mode to "Windows 7"
- Hit "Apply", then "OK" to save the changes.
- Please RESTART your PC now. Once your PC has been restarted, Right-Click the FFXIV launcher icon once more and select "Run as Administrator"

2) Make sure your anti-virus/firewall has the appropriate exceptions for Final Fantasy XIV

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

4) Change your DNS to 8.8.8.8 or 1.1.1.1
- Go to the Control Panel
- Click Network and Internet > Network and Sharing Center > Change adapter settings
- Right-click on the connection you are using and select Properties
- Under the Networking tab you will see a long list of available options
- Scroll down and doubleclick on Internet Protocol Version 4 (TCP/IPv4)
- Select 'Use the following DNS server addresses'

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