Modern Smart TV from the company LG While TVs are designed to be constantly connected to the global network, users often need to disconnect. This may be due to a desire to save data, limit children's access to content, or simply eliminate interference the wireless module creates for other devices. In some cases, the TV automatically searches for a network or broadcasts data in the background, requiring user intervention.
The disconnection process isn't always obvious, as manufacturers strive to make the interface as user-friendly and "always online" as possible. There are several ways to connect, from simply deleting the network profile in the menu to more drastic measures like resetting network settings or disabling features. Digital Living Network AllianceThe specific method you choose depends on your device model and the version of the operating system installed. webOS.
In this article, we'll detail all available options, explain the difference between a temporary disconnect and a hard reset, and explore the nuances of different software versions. You'll learn how to prevent automatic reconnection and what hidden features can prevent a complete disconnect from the router.
Disabling via the main settings menu
The most obvious and safest way to disconnect is to use your TV's built-in menu. To do this, you'll need your remote control. Magic Remote or a standard IR remote. Click the gear button or the "Settings" icon to open the quick menu and select "All settings" at the bottom of the screen.
Further, the interface may differ depending on the version webOSIn new models, you need to go to the section General or Net, and then select the item Wi-Fi connectionHere you'll see a list of available networks and their current connection status. To disconnect, simply toggle the slider to "Off" or select "Disconnect" next to your network name.
In older versions of the operating system the path may look like this Settings → Network → Network connection → Wi-FiAfter entering this section, the system will offer you a choice between a wired and wireless connection. Make sure the switch is turned on. Wi-Fi is inactive. If the TV tries to automatically reconnect, the "Auto-connect" feature may be enabled in the settings, which also needs to be disabled.
⚠️ Please note: Disabling Wi-Fi will disable Smart TV features, including online cinemas, weather widgets, and voice control. The TV will only function as a monitor for HDMI inputs or digital TV.
It's important to note that simply moving the slider doesn't always delete the saved password. If you plan to give the TV to someone else or sell it, it's best to use the network deletion feature to ensure that the data isn't stored in the device's memory.
Deleting saved networks and resetting settings
If your goal is not just to temporarily disconnect, but to completely clear your TV's memory of your home network data, you'll need to delete the profile. This is especially important if you're selling the device or if you've changed the router and password, but the TV continues to attempt to connect to the old access point with an error.
To perform this operation, go to the menu Settings → All settings → Network. Find the item Wi-Fi connection and open the list of saved networks. This is usually located in the "Network List" or "Connection History" section. Select your network and press the "Delete" button or the trash can icon on your remote. The system will ask you to confirm the action.
In some cases, especially when software glitches occur, a simple uninstall isn't enough. A full network settings reset can then be the solution. This function returns all network settings to factory defaults without affecting personal files or installed apps. The path to this function typically looks like this: Settings → All settings → General → Factory reset (or a similar item in the Network section).
- 📱 Open the Settings menu and go to the "Network" section.
- 🗑️ Select "Delete network" to clear the list of saved access points.
- ⚙️ If necessary, reset your network settings through the General menu.
- 🔄 Restart your TV to apply the changes.
After the reset, the TV will behave as if it were new in terms of network connections. The next time you turn it on, it will prompt you to reselect the language and connect to the network, unless you prevent this by disabling Wi-Fi during the initial setup.
☑️ Pre-reset check
Disabling DLNA and Smart Share
Often users want to disable Wi-Fi not completely, but just prohibit the TV LG stream content from other devices or be visible online. This is what technology is responsible for DLNA and signature feature Smart ShareEven if the TV is connected to a router, disabling these services will make it "invisible" to smartphones and computers.
To manage these settings, go to the menu Settings → All settings → ConnectionsHere you will find the item Connecting a mobile device or DLNAIn the menu that opens, you can disable media file reception or deny access to specific devices. In some versions webOS This feature is called "Screen Share" and has its own switch.
It's also worth paying attention to your privacy settings. In the section General → About TV → Additional settings (or similar) often hides options that allow usage data collection and ad personalization, which also require an active internet connection. Disabling these options reduces the TV's network activity, even if it is formally connected to Wi-Fi.
⚠️ Note: The menu interface may vary depending on the model year. If you don't see these options, check for software updates or refer to the manual for your specific model. LG OLED or LG NanoCell.
Disabling DLNA is useful if you want to prevent your child's phone from accidentally playing videos on the big screen or protect your network from unauthorized access through your TV.
Why does the TV turn on Wi-Fi by itself?
Some LG models have a feature that automatically turns on Wi-Fi when launching a Smart TV or updating apps. This behavior is built into the webOS operating system to ensure widgets are up-to-date. This can only be completely disabled by disabling the module in the engineering menu (not recommended) or physically disabling it.
Using guest mode and access restrictions
If you need to temporarily restrict your TV's internet access, for example, when you have guests or to control viewing time, you can use parental controls or your router's settings. While this doesn't disable the TV's Wi-Fi module, it does improve data transfer efficiency.
Modern routers have a “Guest Network” function or the ability to block devices by MAC addressYou can find the MAC address of your TV in the menu. Settings → All settings → General → About TV → TV information → Wi-Fi network connectionBy adding this address to your router's blacklist, you'll prevent your TV from accessing the internet, even if it's connected to Wi-Fi.
An alternative method is to use the Parental Control feature on your TV itself, if it is available on your version. webOSYou can set restrictions on app or internet browser use there. However, this method is less secure, as it often requires entering a PIN only when launching apps, not when connecting to the internet.
| Limit method | Complexity | Efficiency | Impact on Smart functions |
|---|---|---|---|
| Turning off Wi-Fi in the menu | Low | 100% | Complete shutdown |
| Removing a network | Low | High | Requires password re-entry |
| Blocking in the router | Average | 100% | Smart functions don't work |
| Disabling DLNA | Low | Partial | Online services are working |
Using router-side blocking is the most reliable method of control, as the TV user will not be able to regain access without changing the router's settings.
Automatic connection problems and their solutions
One of the common complaints from owners LG The problem is that the TV persistently tries to connect to Wi-Fi immediately after turning on, even if the connection was previously broken. This behavior is due to algorithms webOS, which prioritize online status for widget updates and license verification.
To minimize this issue, make sure the "Auto-connect" option is disabled in the network settings (if available on your model). It's also worth checking the list of apps running in the background. Some of them may initiate a connection request. Go to Settings → General → Additional settings → Power saving mode and try activating the mode that limits background activity.
If your TV continues to behave incorrectly, perform a power cycle: turn off the TV using the remote, then unplug it for 1-2 minutes. This will clear the temporary network service cache. After turning it on, check the connection status again.
In rare cases, outdated firmware may be the cause. Check the software version in the section General → About TV → Check for updatesIf a new version is available, install it while connected to the network, as updates often contain bug fixes for network modules.
Frequently Asked Questions (FAQ)
Is it possible to physically disable the Wi-Fi module inside an LG TV?
Theoretically, yes, but this requires disassembling the case and disconnecting the antenna cable or module from the motherboard. However, this will void the warranty and may interfere with other wireless-dependent functions (such as the Magic Remote on some models). It is not recommended to attempt this without electronic repair skills.
Does disabling Wi-Fi affect the operation of digital television (DVB-T2)?
No, it doesn't. Digital terrestrial television is received via the built-in tuner and antenna cable. Wi-Fi is only required for Smart features, online cinemas, and system updates. You can easily watch regular channels without an internet connection.
Why does my TV ask me to connect to Wi-Fi again after resetting it?
After a factory reset, the TV returns to its "as-is" state. Initial setup webOS Always requires a network connection to set the correct time, region, and updates. You can skip this step by selecting "Configure Later" or "Use Offline," if available in your software version.
Will the Magic Remote work without Wi-Fi?
The remote's basic functions (cursor, navigation buttons) operate via Bluetooth, which is a separate module but often linked to network settings. However, if Wi-Fi is completely disabled, some smart remote features, such as voice search, will not work, as voice processing is performed on servers. Standard controls will remain available.
