Terrible lag and dc on ps4 with ATT Internet

[3lysium]

Ps4 player, for the last week starting 4/4/21-4/11/21(today) Lagging for minutes at a time and disconnecting from the game for a week while in savage instances from 9:00 -11:00pmEST , disconnected 5 times in an hour and it’s unbearable. AT&T replaced my modem 4/10 and rebooted gateway and I am still experiencing the same issues. I keep reading about Comcast but I don’t have Comcast. Have not had issues like this before. Been subscribing since ARR, please fix!

The issue is not (completely, at least) on Comcast/xfinity, but on Square's Datacenter and Internet Provider, NTT (which is NOT the same as ATT, many people misuse the abbreviation).

Same issue, Xfininity ISP, started around a week ago and game lags EVERYDAY at the SAME time. starts ~9pm CST.

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

We apologize for the delay in responding. Please try the following troubleshooting steps:

- Please make sure that "Cookies" and "JavaScript" are ENABLED on the PSN browser. If they are already checked, please uncheck them then recheck them.
- The issue could also be from the "Date & Time" settings on your PS4.
1. Close the FINAL FANTASY XIV game/application.
2. Go to [SETTINGS] on your PS4
3. Select [Date and Time], and "Set via Internet". (Please do not manually set the date and time.)
4. Once the date and time have been updated, please restart your PS4 console.
5. Once the console has fully restarted, please start the FINAL FANTASY XIV game/application.

Please make sure all other internet-enabled devices (including smartphones, laptop/desktop PCs, tablets, etc.) have been disabled and/or turned OFF to minimize game interference.

If the above steps do not resolve the issue, please check to see if the following port ranges are opened on your router. You can contact your ISP and request they open them for you:
▼TCP
54992 through 54994,
55006 through 55007,
55021 through 55040
