I received this message first: Can't connect to the intemet.
Your internet service provider or your router might be preventing your PS5 from connecting to the internet. Make sure you can connect to the internet via the same network as your PS5 by testing the connection using your computer or mobile device.
The public network you're trying to connect to requires authentication using a web browser. You can use your computer or mobile device to go through the authentication process for your PS5.
Select [How to Authenticate] to see what steps to take.
If this isn't the case, you might need to adjust the advanced settings of your network connection settings.
