An LG C3 OLED that will not connect to Wi-Fi, keeps dropping its connection or shows a network error has a problem in the TV's settings, the router or the signal, and the C3 offers several tools for finding it. This 2023 OLED evo runs webOS 23 and joins 2.4 and 5 gigahertz networks. Without a connection the TV's apps, updates and screen sharing do not work, so a Wi-Fi fault is felt at once. Start with the TV's settings. Press the settings button and go to All Settings, Connection, Wi-Fi Connection, and choose your network, entering the password carefully; a mistyped password is the commonest cause of failure. If the TV shows connected with no internet, open Network Status to see which step failed:
The checks in more detail
the TV, the gateway or the internet. Check the date and time under General, since a wrong time causes security failures. Turn the TV off and unplug it for a minute, which clears a stuck connection. In the Connection settings, forget the network and add it again. Then the router. Restart the router by unplugging it for 30 seconds. Check that other devices work on the network. If your router combines the 2.4 and 5 gigahertz bands under a single name, try joining the 5 gigahertz band for speed or the 2.4 gigahertz band for range, depending on the distance. Move the router closer or remove obstacles; a TV mounted on a wall behind a metal frame can have a weak signal.
Check for a MAC filter or a device limit. In Advanced Wi-Fi Settings, you can set a manual DNS such as 8.8.8.8, which cures some connection and app problems. The best fix is a cable: connect an Ethernet cable from the router to the TV's LAN port, which gives a stable link and the best streaming quality. Use a Wi-Fi extender or a mesh node near the TV if a cable is not possible. Update the TV's software once connected, and reset the network settings if needed. If the TV still cannot connect to any network, a hardware fault in the Wi-Fi module is possible, and LG support with the model number can advise. An LG TV adds a few features of its own to a connection problem.
The Wi-Fi settings let you see the signal strength of each network in the list, and LG's Quick Help in the support menu can run a connection check; use it before experimenting. If the TV connects but a streaming app buffers, run the app's own speed test and compare with your plan, since a 4K stream needs a steady connection of 25 megabits per second or more. A TV on a wall bracket can have its Wi-Fi antenna shadowed by the wall or a metal frame, so a small move of the router or a mesh node may do more than any setting. Turn off Wake on LAN and similar standby features if the TV fails to connect after standby.

- 1
A wrong password or a stale entry
What separates it The connection fails to authenticate
How to confirm Forget the network and re-enter the password
- 2
A weak signal
What separates it Dropouts and buffering
How to confirm Move the router, add a node or use Ethernet
- 3
A router fault or filter
What separates it All devices fail or the TV alone is blocked
How to confirm Restart the router and check filters
- 4
A wrong date and time or a DNS fault
What separates it Connected with no internet
How to confirm Set the time and a manual DNS
- 5
A stuck TV network state
What separates it Nothing connects
How to confirm Unplug the TV for a minute
