[LG TV Internet Connection] I cannot connect to the Internet and is prompted with a connection failure message (DNS error)

Troubleshooting

Causes and Symptoms

  • Internet connection fails when I connect to a wired/wireless network.
  • My network connection appears with an error sign.

Try this

1. If you have connected to a wired network, check the LAN cable, router, and socket on the wall for any issues.

2. Remove the LAN cable from the TV and test the connectivity by connecting it to your PC.

3. If you have connected to a wired network requiring a fixed IP address, select Edit to specify the details.

4. Check if there is any section with an [X] mark on it, and check the status, if any.

Keep seeing the same prompt?

ⓐ Turn off your router, wait for 1 to 2 minutes, turn it back on, and check the connection again.

ⓑ Plug the LAN cable into another port in the router and check the connection again.

E.g.) Unplug the LAN cable from Port #1 and plug it into Port #2.

How to check the network status in different products

Checking the network status by stage

➔ Check if there is any [X] mark between stage icons on the Network Connection Status screen.

① The icons on the screen correspond to [TV], [Gateway], [DNS], and [Internet] (from left to right).
If all stages have no issues, all the icons are connected via a green line.

① If there is an [X] mark between [TV] and [Gateway], then check the cable connection between your TV and router.
If there are no issues, restart the cable modem and then router in the specified order, and initialize them.
After the initialization, turn off your TV, turn it back on, and connect it to the network again.

Press the [Reset] button on your router and cable modem to initialize them.
If the problem persists, contact your Internet service provider.
