This guide explains how to check your LG TV’s network connection status and identify where a wired (Ethernet) connection is failing so you can restore internet access and confirm expected network performance.
If your LG TV cannot reach the internet or the connection is unstable, the issue is commonly caused by a physical cable problem, a temporary router modem error, or an outage or line issue from your Internet Service Provider (ISP). Checking the TV’s wired network status helps you pinpoint where the connection is failing.
The LAN cable may be loose, disconnected, or damaged. A poor connection can reduce throughput or prevent the TV from obtaining network settings.
Your router or modem may have a temporary system error and fail to provide an IP address or route traffic to the internet.
If your home network equipment is working but the internet line is down, the TV may show a connection failure even though the LAN link is active.
1) Connect a LAN cable from the wall socket to the router’s WAN (Internet) port.
2) Connect the router’s LAN port to the LAN port on the back of the TV using a LAN cable.
Note: You can connect the TV directly to the wall outlet without a router, but depending on your home network environment, the TV may not receive an IP address. Verify your network setup before connecting directly.
Setting: Settings > All Settings > Connection > Wired Connection (Ethernet)
1) Press the Settings button on the remote.
2) Open All Settings, then select General.
3) Select Network, Wired Connection (Ethernet) and confirm whether the TV shows as connected.
If the TV is not connected, open the network status details to locate the point marked with an “X”.
Cause: The TV is not communicating with the router.
What to do:
1) Reseat the LAN cable at both the TV and router ports.
2) Try a different LAN cable if available.
3) Power-cycle the router: unplug the router power cord, wait 10 seconds, then plug it back in.
4) Recheck the wired connection status on the TV.
Cause: The TV is connected to the router, but the router is not receiving or properly routing an internet signal.
What to do:
1) Power-cycle the router (unplug, wait 10 seconds, plug back in).
2) If you use a separate ISP modem, check its status lights and reboot it if needed.
3) After the network restarts, check the TV’s wired connection status again.
Cause: The internet line or ISP service may be down.
What to do:
1) Confirm whether other devices on the same network can access the internet.
2) If multiple devices are affected, contact your ISP and request a line,service check.
3) After the ISP confirms service is restored, recheck the TV connection status.
1) Fully power-cycle the TV: unplug the TV power cord, wait 1 minute, then plug it back in.
2) Reboot the router.
3) If the issue continues, replace the LAN cable and test again.
