Navigate to Settings > General > Network > Network Status.
A status test will run, click cancel and then select IP Settings.
Navigate to and select DNS Setting > Enter Manually.
Navigate to and select DNS Server.
Enter 8.8.8.8. This may be difficult to do with a smart remote, make sure you select each 8 with the number select that appears at the bottom of the screen and then select the arrow after. When complete, select done on the number selector. If the number selector disappears, selecting DNS Server again will make it reappear.
Try the connection again. If the connection fails, continue troubleshooting.
Power-cycle your network.
Unplug your router, modem, or both, and your TV.
Wait 2 minutes.
Plug in your modem and wait for all the lights to come on. Do the same for your router (if you have both).
Plug in your TV.
Try the network connection again.
If the TV connects to the home network, but not the internet, there is not an issue with the TV, but your internet service may be having an issue. We suggest contacting your internet service provider to see if there is an outage in your area.
