Why might you need to disable Wi-Fi on your LG TV via your phone?

At first glance, disabling Wi-Fi on a TV seems like a trivial task—but there are several scenarios where a remote control becomes a necessity:

• 🔌 Energy saving: even in standby mode, the Wi-Fi module consumes up to 2–5 W/h, which over the course of a year adds up to a significant overpayment for electricity.
• 🛡️ Security: If your TV is connected to a public network (such as in a hotel or cafe), disabling Wi-Fi prevents potential data leaks through vulnerabilities in WebOS.
• 🎮 Conflicts with other devices: some games or streaming services (eg. GeForce NOW or Moonlight) may conflict with the TV's background updates.
• 📶 Connection problems: If the router issues IP addresses in the wrong range, the TV may get stuck in a connection loop, blocking other devices.

In addition, on the models LG With WebOS 6.0 and later the function is activated Auto Wi-Fi Reconnect, which automatically reconnects when a familiar network is detected. This is useful for home use, but can be problematic on guest networks or when selling the TV. Remote shutdown allows you to bypass this mechanism without physical access to the remote control.
