Modern Smart TV from LG Automatically remember all connected wireless networks—this is convenient until you have to delete the old access point. Perhaps you've changed your router, forgotten your network password, or want to prevent automatic connections to an untrusted one. Wi-FiUnlike smartphones, TV interfaces often hide obvious options, and manufacturer instructions are silent about the nuances.

The problem is complicated by the fact that the models LG on the platform webOS (2014–2026) and older TVs with NetCast (before 2013) have different settings menus. Even within the same line - for example, LG OLED C2 vs LG NanoCell 86 — The paths to deleting a network may vary. This article covers all current firmware versions and provides clear instructions, including alternative methods for frozen menus or blocked options.

We'll cover not only the standard deletion method via settings, but also forced reset methods, which are useful if the TV stubbornly clings to the old network. Special attention is given to security: Why simply "forgetting" a network isn't always enough and how to completely erase its traces from your TV's memory.

1. Standard deletion of a Wi-Fi network via the settings menu

On most TVs LG With webOS (including models OLED A1/A2/C1/C2, QNED, NanoCell (2018–2026) deleting a network takes no more than a minute. The key is to know the exact menu path, as the manufacturer periodically moves menu items in new firmware versions.

Open Remote control and follow the steps:

1. Click the button ⚙️ Settings (or ⚙️ Settings on English-language firmware).
2. Go to the section Network → Connect to Wi-Fi (Network → Wi-Fi Connection).
3. From the list of saved networks, select the one you want to delete.
4. Press and hold the button OK on the remote control (or click on trash can icon ❌, if it is displayed).
5. Confirm the action in the pop-up window.

If the trash can icon is missing, try this alternative path:

6. Select the network and click the button ⚙️ (or ⋮) on the remote control to open the context menu.
7. Select Delete network (Forget Network).

An important nuance: on some models (eg, LG UK6300) After deleting a network, the TV may automatically start scanning for new access points. To avoid this, Disable your Wi-Fi adapter on the menu Settings → Network → Wi-Fi → Turn off to deletions.

⚠️ Attention: If the TV is connected to the network via WPS (button on the router), its traces may remain in memory even after deletion. In this case, it is necessary full reset of network settings.

2. Removing the network on older LG models (NetCast, 2010–2013)

Televisions LG up to 2014 release work on the platform NetCast and have a stripped-down interface. There's no traditional "forgetting" of the network—instead, it uses manual entry of settings followed by a reset.

Instructions for models LG 42LM620T, LG 55LA620V and similar:

1. Open Menu → Settings → Network → Network Setup.
2. Select Manual setup (Manual Setup).
3. In the field SSID enter arbitrary name (For example, DELETE_ME).
4. In the field Password Enter any characters.
5. Save the settings - the TV will try to connect and give an error.
6. Return to Network settings and select Factory reset (Reset to Default).

This method works because NetCast It can't "forget" networks—it simply overwrites the current settings with new ones. After a reset, all saved access points will be erased.

Why doesn't the "Delete" button work on NetCast?

On the NetCast platform, the interface is controlled through a simplified browser engine. The delete button may not appear due to memory limitations or outdated firmware. In this case, the only reliable solution is a manual reset, as described above.

If after the reset the TV still connects to the old network, check:

• 🔌 Router settings: the function may be enabled Wi-Fi Protected Setup (WPS), which automatically links devices.
• 📡 Hidden networks: NetCast can remember SSID, even if it does not appear in the list.
• 🔄 DNS cache: click Menu → Settings → Network → Reset DNS (if the item is available).

FAQ: Frequently asked questions about removing Wi-Fi on LG TV

Is it possible to delete a Wi-Fi network without a remote?

Yes, but the methods are limited:

• 🎮 Use gamepad (for example, from Xbox or PlayStation), connected via Bluetooth.
• 🖱️ Connect USB mouse to the TV port - in webOS Cursor control is supported.
• 📱 Install the application LG TV Plus to your smartphone (requires connection to the same network).

If the remote control is lost and alternative devices are unavailable, the only option left is hard reset (button Reset on the back of the TV).

Why does the TV ask for a password for a network that I have already deleted?

This happens because:

• 🔄 Caching: reboot your TV (Settings → General → Restart).
• 📡 Dual SSID: the router can broadcast one network on two frequencies (2.4 GHz And 5 GHz). Delete both.
• 🔧 Firmware errors: Update your TV software to the latest version.

How do I delete a network if my TV freezes when I enter settings?

Try these methods:

1. Unplug your TV for 10 minutes, then try again.
2. Use alternative remote control (for example, universal Logitech Harmony).
3. Do it reset via service menu (cm. Section 4).
4. If nothing helps, contact LG service center — the problem may be in the hardware.

Is it possible to delete a Wi-Fi network via a computer?

No, you can't do it directly. But you can:

• 🖥️ Change router settings: hide SSID or change the password - the TV will lose access.
• 🔌 Use Telnet/SSH: on some firmware versions webOS You can connect to the TV via the network and run the command:

  echo "remove_network" | nc 192.168.x.x 3000

  (requires technical knowledge and included ADB on TV).

For most users, it is easier to use the standard methods through the TV menu.

What should I do if after deleting a network the TV does not see other Wi-Fi networks?

The problem is typical for models with damaged Wi-Fi module. Check:

• 🔍 Wi-Fi antenna: on some TVs (LG 43UK6200) it is connected via a connector coaxial - Make sure the cable has not come loose.
• 🔄 Router operating mode: televisions LG do not support 80 MHz channel width by 5 GHz — install 40 MHz.
• 📡 Interfering devices: Turn off microwaves, cordless phones and other sources of interference.

If the problem persists, try connecting via Ethernet and update the TV firmware.
