To troubleshoot internet connection on your Smart TV, consider the following steps:
- Check the network cables are securely connected to the back of the router, TV, and wall socket with the correct media type.
- Check that the router is on and you are connected to the same network that the TV is connected to.
- Check if the router has a WPS button, and press it if the TV has a WPS button as well.
- Check that the wireless connection is properly configured on the TV and that the wireless settings have not been changed inadvertently.
- Check that the IP settings of the TV is set up correctly.
- Reboot the router and the TV, and then try reconnecting.
