Wireless network issues on TVs LG — is one of the most common, and the causes can be rooted in both the device's settings and external factors. Unlike smartphones or laptops, where restoring the network often boils down to a reboot, smart TVs It's more complicated: there's no familiar Android interface, and the system menus are hidden behind several levels of settings.

In this article we will look at All possible reasons for Wi-Fi disappearance on LG TV — from the mundane (like a disconnected router) to technical issues (like a damaged Wi-Fi module). You'll learn how to diagnose the problem yourself, which settings to check first, and when it's really worth contacting a service center. We'll pay special attention to models with webOS (series OLED C1/C2, NanoCell, QNED), since their firmware most often becomes the source of failures.

Before you start repairs, answer two questions: 1. Did the problem appear after updating the firmware or changing the router settings? 2. Are other devices (phone, laptop) connected to the same Wi-Fi network?

The answers will help narrow down the possible causes and save time.
