If it's the same issue as me, it is 100% a FFXIV game/server issue, and not ISP/client based. While some users may indeed have network issues, mine and other players with similar posts, are definitely not.

To test if your issue is ISP based, you can run tracert to your game server (to find out which server, you can use Windows Resource Monitor, instructions below) If you see any packet loss or massive latency (>400-500ms), it's possibly network related. If you don't have Packet Loss or Latency issues, and all the FFXIV support suggestions don't work, you may have the same issue as me.

I have 2 different PC's on the same network. On one PC, I did ALL of the suggestions Square recommended, reinstalled the game, ran network diagnostics, etc. On another PC, none of the changes, and yet I still have the issue on both PC's.

Interestingly and what proves it's FFXIV server/game issue, is that on both PCs, other members of the household have ZERO issues playing FFXIV on their accounts. No disconnects ever. Not once. And when I look at resource monitor server connections for both accounts, they connect to different IPs, even though we are both on Midgardsormr server.

Also, I've run resource monitor on Windows that tracks the TCP connections to FFXIV servers, and when I get disconnected... it records 0 packet loss, and 0 latency issues. (Windows Key + r, type in 'resmon' then enter to run Resource Monitor, then look under TCP Connections and find ffxiv_dx11.exe to see the server / connection details.

While I'm sure there are people who do have client/ISP issues, I have concrete proof that my issue is a FFXIV server/game issue. But unfortunately I haven't been able to get a support rep's response to dig into it, even though I've reached out via Support Ticket, GM Ticket, and these forums in the last week.

Hopefully my troubleshooting can help you with yours as well, and Square Enix can use to resolve this. Good luck!
