How to Disable Wi-Fi on an LG TV: 5 Proven Methods

Disconnection Wi-Fi on an LG TV It may be needed in a variety of situations: from simply saving the remote control battery (yes, some models consume energy more actively when the network connection is turned on) to solving problems with firmware freezing or IP address conflicts on the local network. But while disconnecting the internet on a smartphone or laptop is intuitive, the interface webOS or older versions NetCast often leaves users confused. Especially when it comes to models with automatic connection to saved networks after software updates.

Many people mistakenly think that simply removing the power cable will break the connection. In fact, LG TV stores Wi-Fi settings in non-volatile memory, and the next time you turn it on, it may reconnect to the network, even if you didn't intend to. In this article, we'll cover all the current methods for disabling it—from the standard menu route to more drastic methods like resetting network settings or using the service menu. We'll also explain why it's sometimes better to limit Wi-Fi functionality rather than completely disable it.

If your TV was released before 2016, the interface may differ significantly. In this case, please refer to the section about old models or check the firmware version in Settings → General Information → About TV.

1. Standard method: via the settings menu

This is the most obvious and safest method that works on 90% of LG models With webOS (since 2014). The instructions are universal for the series OLED C1/C2, NanoCell 86/90, QNED and budgetary UK6300/UK7500The main condition is that the TV must be turned on and respond to the remote control.

Algorithm of actions:

1. Click the button Settings (gear) on the remote control.
2. Go to the section All Settings → Network → Wi-Fi Connection.
3. Select the active network (marked with a check mark) and press Disable.
4. Confirm the action if prompted.

⚠️ Attention: On some models (eg, LG OLED A1 2021) after disabling Wi-Fi, the TV may prompt you to go to offline modeThis is not necessary - just click Close or Back.

If the item Disable missing, try an alternative path:

• 🔄 Network reboot: In the same section Net select Network reset → Reset Wi-Fi settingsThis will delete all saved passwords.
• 📵 Airplane mode: IN All Settings → General → Airplane Mode Flip the switch. This will turn off both Wi-Fi and Bluetooth.

2. Switching off using the remote control (hot keys)

Not everyone knows, but on the remotes LG Magic Remote (comes with 2017 and newer models) yes key combinations, allowing you to quickly manage your network without diving deep into menus. This is convenient if your TV is glitching and not responding to regular commands.

Methods:

• 🔘 Button Home: Hold it for 5-7 seconds until the quick access menu appears. There may be an item here Net with the option to turn it off.
• 🔄 Combination Settings + Back: Press and hold both buttons for 3 seconds. The service menu (not to be confused with the engineering menu!) will appear on the screen, where you can select Network Off.
• 📶 Button Wi-Fi Direct: Older remotes (pre-2016) have a separate button for controlling wireless modules. Pressing it once can disconnect the connection.

⚠️ Attention: On models with webOS 6.0 and later (For example, LG G2 2022) Button combinations may not work due to modified control logic. In this case, use the standard menu method.

If the remote control does not respond, check:

1. Battery charge (the green light on the remote control display should be on when pressed).
2. There are no physical obstacles between the remote control and the TV's IR receiver.
3. Availability of software updates for the remote control (relevant for Magic Remote AN-MR21 and newer).

3. Service menu: for experienced users

This method is suitable if standard methods do not work, for example, due to firmware failure or when the TV constantly reconnects to Wi-Fi after rebooting. Service menu (not to be confused with engineering!) allows you to manually deactivate the network module, but requires caution - incorrect actions can lead to a reset of all settings.

Instructions for webOS (2014–2026 models):

1. Turn off the TV using the remote control.
2. Press and hold the button Settings on the remote control, while simultaneously turning on the TV with the power button.
3. Hold Settings until the menu with the inscription appears Service Menu (usually 10-15 seconds).
4. Go to the section Network → Wi-Fi Control.
5. Select Disable and confirm.
6. Save settings (Save & Exit) and reboot the TV.

⚠️ Attention: On models with webOS 5.0 and later (For example, LG CX 2020) the path may differ: Service Menu → Option → Network → Wi-Fi OffDo not change other parameters in the service menu - this may lead to loss of warranty or unstable operation of the TV.

For models with NetCast (before 2014) the process is more complicated:

NetCast Instructions

Turn on your TV and quickly press the following sequence: Menu → 4725 (on older remotes) or Settings → 0000 (on new ones). In the menu that opens, select Network → Wi-Fi DisableBe careful: you can accidentally reset your region or block channels here.

4. Reset network settings (hard method)

If your TV stubbornly connects to Wi-Fi spontaneously (for example, after a firmware update), it might help complete reset of network settingsThis method deletes all saved networks, passwords, and IP settings, returning the TV to its factory default settings in terms of connections.

How to do:

1. Open Settings → All settings → Network.
2. Select Network reset (or Network restoration on older models).
3. Confirm the action. The TV will reboot.

After reset:

• 🔒 All Wi-Fi passwords will be erased. You will have to enter them again if you need to connect later.
• 📡 IP/DNS settings will be reset to automatic mode. If you have a static IP, you will need to reconfigure it.
• 🔄 Some applications (eg. LG ThinQ) may require re-authorization.

⚠️ Note: On models with webOS 3.0 and below (For example, LG 49UH610V) resetting the network can also reset the settings at the same time Smart TV, including your LG account. Before proceeding, please make sure you remember your account login and password.

5. Physically disabling the Wi-Fi module (for advanced users)

In rare cases, for example, when hardware failure of the network card or if the TV is used in highly confidential environments (government agencies, military facilities) - it may be necessary complete physical shutdown of the Wi-Fi moduleThis is a radical method that requires disassembling the TV and voiding the warranty.

How does this work:

• 🔧 Module localization: In most LG models, the Wi-Fi/Bluetooth module is located on a separate board next to the main processor. OLED TVs It can be integrated into the motherboard.
• 🔌 Disabling antennas: The module is connected to two small antennas (usually black or gray). They can be carefully removed, but this requires a soldering iron.
• 🚫 Software blocking: Some boards have a jumper (jumper), which can be cut to permanently disable the module.

⚠️ Attention: Disassembling a TV yourself LG This will void your warranty. If you're unsure of your skills, contact a service center. Also note that physically disconnecting Wi-Fi will cause the following to stop working:

• All online services (Netflix, YouTube, LG Channels).
• Functions Screen Share And Miracast.
• Over-the-air firmware updates (you will have to use USB).

If you decide to disassemble it, prepare:

1. Set of screwdrivers TORX T5–T10 (for modern models).
2. Plastic spatulas for separating the housing.
3. Antistatic wrist strap (to prevent damage to electronic components).

What should I do if the TV doesn't turn on after disassembling it?

Check the connections of all cables and boards. A common error is an incorrectly connected power connector to the motherboard. If the screen remains black but the indicator light remains on, the problem may be with the power supply or firmware.

6. Disabling Wi-Fi on older LG models (before 2014)

Televisions LG with a platform NetCast (for example, series LM6200, LA620V) have a stripped-down interface, where network settings are hidden deeper. Moreover, many of them do not support webOS and have unique ways of managing connections.

Instructions for NetCast:

1. Click the button Home on the remote control.
2. Go to Settings → Network → Network settings.
3. Select Wireless network → Disable.
4. If the point Disable no, please select Manual setup and enter a non-existent one SSID (For example, OFFLINE).

Features of older models:

• 🕒 Long shutdown: On some TVs the process may take up to 1-2 minutes.
• 🔄 Auto-connection: After rebooting, the TV may search for networks again. To avoid this, reset the network settings through the service menu (see Section 3).
• 📶 Limited functionality: No Wi-Fi on NetCast Even local functions like DLNA.

⚠️ Attention: On TVs LG 2010–2013 years of production (for example, LE5500) It may not be possible to completely disable Wi-Fi through the menu. In this case, the only solution is to physically disable the module or use router with device blocking function (block the TV's MAC address in your router settings).

7. Troubleshooting Wi-Fi disconnects

Sometimes TV LG Behaves illogically: for example, it shows that Wi-Fi is disabled but apps continue to work online, or, conversely, it fails to connect to the network even though the settings are correct. Let's look at common errors and their solutions.

Problem 1: The TV connects to Wi-Fi automatically after being turned off.

• 🔌 Solution: Disable the feature Quick start V Settings → General → Eco ModeIt keeps the TV in a "sleep" state with the network module active.

Problem 2: After resetting the network, Wi-Fi does not turn back on.

• 🔄 Solution: Restart your TV (unplug it from the power outlet for 1 minute). If that doesn't help, update the firmware via USB.

Problem 3: Applications (Netflix, Prime Video) work without the Internet.

• 📥 Solution: This is cached content. To completely disable online features, clear the app cache in Settings → General → Storage.

Problem 4: The TV does not see the network after turning Wi-Fi off/on.

• 📡 Solution: Check your router settings: MAC address filtering may be enabled or DHCP disabled. You can also try manually setting the IP address in your TV settings.

If none of the methods helped, check:

☑️ Troubleshooting

The TV responds to the remote control (replace the batteries) → The Wi-Fi indicator on the router is blinking (the network is active) → There are no error messages on the TV (codes like 102 or 3006)→The problem occurs on all networks (check from a mobile hotspot)

Completed: 0 / 1

⚠️ Attention: If the TV gives an error 3006 ("Unable to connect to the network"), this may indicate hardware failure of the Wi-Fi moduleIn this case, disabling the network through the menu won't help—the board will need to be repaired or replaced.
