My hisense it has been caught to have one of these problems: Prix IP; foreign IP or public internet foreign IP. How can I fix

Solution
More information is needed.

What/Who is telling you that your Hisense has been "caught"?

The TV should be receiving its IP address via your router. Either DHCP IP (will change IP within your network) or a Static IP (which will remain the same within your network).

Do you have the TV's manual? Check the default IP address assigned to the TV.

You may need to reconfigure the TV so it can be assigned an IP address and subnet mask applicable to your network.
