Thanks for giving it a shot.
Have you had a chance to try changing the DNS on your PS4 to see if that makes any difference at all? I've seen some cases where using a different DNS can help with issues like this. To change the DNS settings on your PS4 follow the steps below:
1. Open your PS4 Settings and go to Network
2. Select Set Up Internet Connection
3. Choose WiFi or LAN Cable depending on what type of connection you're using
4. Select IP Address Settings (automatic)
5. Select DHCP Host Name (Do Not Use)
6. Select DNS Settings (Manual)
7. Enter 8.8.8.8 as the Primary DNS and 8.8.4.4 as the Secondary DNS. This is the public Google DNS, but if there's a different DNS you would rather use instead that's OK as well
8. Select MTU Settings (Automatic)
9. Select Proxy Server (Do Not Use)
10. Choose Test Internet Connection to confirm the changes
Let me know if you're still running into the same ping issues afterward. Thanks!
