Still Unable to connect to Wi-Fi It seems the issue is with the network. If using a 5GHz network, we recommend connecting to a 2.4 GHz network to see if it resolved the issue.
If your LG Smart TV encounters connectivity issues while streaming live TV or external content, you can start by ensuring your Wi-Fi connection is stable and your TV's firmware is up-to-date. If problems persist, it may be best to contact LG customer support for expert assistance in resolving the issue.

I had the same problem you describe with my LED 2018 model and had it fixed under warranty. The engineer replaced the Wi-Fi module and the problem hasn’t happened again for several months. The module is super easy to replace and it costs about $50-80. Alternatively the TV could be hardwired to router or node as a workaround.

If your TV is a Smart TV that uses an HDMI port on the set, go to Settings > Network Settings > Network Status and check that both wired and wireless connections are enabled. LG TV WIFI connection problem can be caused by various reasons. Follow the steps below to fix your LG TV WIFI issue: 1. Check Your WiFi Settings
