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

I apologize for the delay in our response. If the disconnections are only happening on your PC, then it's more likely that the issue resides with the configuration specific to your PC. However, if both of your are using the same connection at the same time, you may be running into a bandwidth limitation. Regardless, there is some troubleshooting if you are still experiencing this issue:

1) Make sure your anti-virus has the proper exceptions for Final Fantasy XIV.

2) Try a clean boot. For Windows 7, click Start, type msconfig.exe in the Start Search box, and then press Enter to start the System Configuration utility. On the General tab, click the Selective startup option, and then click to clear the Load startup items check box. On the Services tab, click to select the Hide all Microsoft services check box, and then click Disable all.

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!
