Modern Smart TV LG devices offer users a wide range of entertainment options that rely almost entirely on a constant internet connection. However, there are times when it's necessary to sever this digital umbilical cord: whether it's the desire to watch downloaded content without unnecessary fluff, the need to limit children's access to online features, or simply the desire to minimize background device activity.
Disconnection Wi-Fi module on an LG TV, the procedure is not always obvious, since the operating system interface webOS undergoes changes with each update. In some cases, users want to not just disable a specific network, but completely deactivate the wireless receiver to prevent any connection attempts.
In this guide, we'll cover all available network management methods in detail, from standard menu settings to deeper system parameters. You'll learn how to prevent automatic reconnections and which hidden features may prevent a complete internet shutdown.
Why might you need to disable your wireless network?
The primary reason why owners are looking for a way to turn off WiFi on an LG TV is data securitySmart TVs collect a huge amount of telemetry, and physically or software disabling the communication module is the only guaranteed way to stop the transmission of data about your viewing habits.

In the menu that opens, find the section responsible for connections. Depending on your firmware version, webOSIt may be called "All Settings," "Network," or have a globe icon. Navigate to this section using the remote's navigation buttons.
Within the network menu, you'll see a list of available wireless networks. If the TV is already connected, a "Connected" mark will appear next to your network name. Click the "Disconnect" button or select the "Turn off Wi-Fi" option, which is usually located at the top of the screen or in the overflow menu (the three dots).
☑️ Network shutdown algorithm
After completing these steps network indicator will disappear from the top corner of the screen, indicating the connection has been successfully disconnected. The TV will stop attempting to reconnect to the last access point until you manually restart the connection process.
Using Airplane Mode to Quickly Lock
In newer versions of the operating system webOS 6.0 and above, a function similar to airplane mode in smartphones has appeared. This method is the fastest way to completely disable all wireless interfaces, including Bluetooth and Wi-Fi.
To activate this feature, press and hold the settings button on the remote, or open the control panel (usually by swiping down or using the home button). Look for the airplane icon in the quick actions list.

What happens to Bluetooth in this mode?
Enabling Airplane Mode on your LG TV disables all wireless connections. This means you won't be able to use Bluetooth-enabled wireless headphones or soundbars until Airplane Mode is disabled.
Configuring Smart Share and DLNA settings
Even if you've disconnected from a specific Wi-Fi network, some TV features may remain active in the background, waiting for a connection. These are protocols. DLNA and functions Smart Share, which allow you to stream content from other devices on the local network.
To ensure that your TV isn't visible to other devices and isn't attempting to establish a data connection, you need to go to the sharing settings. Follow the path Settings → General → Manage external device connections (the path may vary depending on the model).
Here, find "Connection Setup" or "Mobile TV Connection" and toggle the switch to "Off." This will prevent pop-up prompts from appearing on your TV screen when someone on your home network tries to display photos or videos on the big screen.
| Function | Default Status | Recommended action | Impact on WiFi |
|---|---|---|---|
| Wi-Fi | Included | Disable | Complete break |
| Smart Share | Included | Disable | Hides TV on the network |
| Quick Start+ | Included | Disable | Reduces background activity |
| Live Plus | Included | Disable | Stops collecting data |
Disabling these services not only increases privacy, but can also slightly speed up the interface, since the system will not need to poll the network for available media servers.
Disabling WPS and automatic connection
One of the reasons why your TV may go online again without your knowledge is if the feature is activated. WPS (Wi-Fi Protected Setup). It allows devices to connect to the router with a simple press of a button, which creates a potential vulnerability.
In the network settings, find the "Additional Settings" or "Advanced WiFi Settings" section. Here, find the "WPS" option and ensure it's disabled. Also, check the "Auto-Connect" setting.
If option auto-connection When enabled, the TV will continuously scan the airwaves and attempt to connect to previously saved networks as soon as they become available. Disabling this feature ensures that the connection will not be restored on its own.
After making changes to these settings, it is recommended to perform a full restart of the device so that the new settings take effect and are saved in non-volatile memory.
Managing network functions through the engineering menu
For advanced users who want to be sure that Wi-Fi module Completely disabled at the hardware level (as far as software allows), access to hidden menus is possible. However, this method requires caution.
The service menu is accessed using a combination of buttons on the remote control (often this is a long press of the Settings button or a combination of buttons on the TV itself and the remote control, specific to each model). Changing settings in the service menu may result in loss of warranty or unstable system operation.
In the engineering menu you can find a section related to Network Setting or WiFi DriverHere you can forcefully disable the wireless network driver. This action is equivalent to physically disabling the antenna, but is performed programmatically.
⚠️ Warning: Accessing the engineering menu is at your own risk. Do not change any parameter values you are not 100% sure of, especially those marked in red.
How to exit the engineering menu?
Typically, pressing the "Return" or "Exit" button several times is enough to exit. In some cases, a full cycle of turning the TV off and on from the power outlet may be required.]]>
How Fast Startup Affects Network Settings
An important aspect that is often forgotten is function Quick Start+When this option is enabled, the TV does not turn off completely, but goes into deep sleep mode, keeping background processes, including network ones, open.
In this mode, the TV can continue downloading updates or sending telemetry data even if it appears to be off. To ensure complete shutdown of all network activity, you must deactivate this feature.
Go to Settings → General → Advanced → Quick Start+ and turn the switch to the "Off" position. Now, when you turn off the TV, it will go through a full boot and unload cycle, resetting all network connections.
