Modern televisions are no longer just devices for watching broadcast channels; they have become complex multimedia centers that require a constant internet connection. However, there are situations when a user needs turn off wireless completelyWhether it's router overload, the need to save bandwidth, or a simple desire to protect data from unauthorized access, smart TV owners often encounter intrusive notifications about available updates or streaming service ads, which can be annoying when watching regular digital television.
The process for disabling the wireless module can vary significantly depending on your display manufacturer and the version of your operating system. Some models simply require disconnecting, while others require a deeper dive. engineering menu or physical manipulation of the router. Understanding how your device's network interface works will help you avoid accidental resets and ensure the stable operation of your entire home network.
In this article, we'll take a detailed look at the steps for the most popular brands, such as Samsung, LG, Sony, and Philips, and also touch on security and traffic optimization. You'll learn why simply turning off your TV doesn't always break the connection, and what hidden features may continue to consume internet bandwidth in the background. Properly configuring your network settings is the first step to creating a comfortable and secure multimedia environment in your home.
Why might you need to disable the Internet on your Smart TV?
Many users wonder about the need to turn off Wi-Fi, believing that smart features should always be on. However, there are scenarios where isolating the TV from the network This isn't a whim, but a necessity. For example, if you use your TV exclusively as a monitor for connecting a gaming console or PC, Smart TV background processes can create unnecessary bandwidth usage, causing lag in online games or video buffering on other devices.
Another important reason is confidentialityModern TVs collect a huge amount of data about viewing habits, which is then used for targeted advertising. By disabling the communication module, you stop transmitting this data to the manufacturer's servers. This also protects the device from potential vulnerabilities, as older firmware versions rarely receive security updates.
⚠️ Note: Disabling Wi-Fi completely will prevent you from using streaming services (Netflix, YouTube), voice control, and Screen Mirroring. Make sure you have an alternative way to receive content, such as an HDMI cable or external antenna.
It's also worth mentioning situations where the router is operating at its limits, supporting dozens of connected devices. In this case, disabling "heavy" devices, such as a TV, which may be constantly downloading updates in the background, will help stabilize the entire home network. This is especially important for apartments with a large number of smart devices.
Universal method via TV settings menu
The easiest and safest way to disconnect is to use your device's built-in menu. While interfaces vary, the logic is similar across most manufacturers. You'll need a remote control and access to the main system configuration sections. Typically, this is done through the Settings, which is often represented by a gear icon.
Within the menu, you need to find the section responsible for network connections. It may have different names: Net, Network, Connection or Wi-Fi DirectAfter entering this section, the system will offer a list of available networks or the status of the current connection. Your task is to find an active connection and select an option. Disable or Forget the network.

It's important to understand the difference between the "Disconnected" and "Forget Network" statuses. The former simply disconnects the current connection, but the TV may automatically reconnect upon reboot. The latter completely erases your Wi-Fi network information (password and name) from the device's memory, ensuring it won't automatically reconnect in the future.

Instructions for Samsung TVs (Tizen OS)
Samsung TVs run the Tizen operating system, which has its own unique interface. To disable Wi-Fi on these models, press the house or gear button on the remote. In the menu that appears, select Settings, then go to the section General or straight to Net, depending on the firmware version.
On the menu Net you will see the item Network settingsClick on it, and the TV will start checking the current status. If the connection is active, a button will appear. DisableAfter clicking, the Wi-Fi module will be deactivated and the antenna icon will disappear from the screen. To completely remove the network, select Delete in the list of saved networks.
Some Samsung models support the feature Smart Things, which may be trying to reconnect to sync with your phone. If the TV still tries to connect after disconnecting Wi-Fi, check the Smart Things app settings in the General → External Device Manager and turn off automatic search.
⚠️ Note: On some Samsung models with the "Universal Remote" feature, disconnecting the power supply may reset the control settings for other devices. Save the remote control configuration before making any changes.
It's also worth noting that the interface may be updated in new 2026-2027 models. If you don't find an exact match, look for sections with similar names, as Samsung periodically changes the menu structure in its software updates.
Setting up a network on LG TVs (WebOS)
LG's webOS interface features a tiled layout and a quick access bar. To turn off Wi-Fi, press the gear button on the Magic Remote. A bar will appear at the top of the screen, allowing you to select All settings (three dots or a gear with sliders).
Select a section in the left menu Net, then Wi-Fi connectionHere you will see a switch that switches the module between active and passive states. Move the slider to the position OffThis action will immediately stop data transmission.
For more in-depth customization, you can go to Additional Wi-Fi settingsThere is a function available there. Access point mode or LG TV Connect, which also use the network module. Disabling the main Wi-Fi connection usually disables these features as well, but it's best to check their status separately to rule out background activity.
| LG model | Path to settings | Peculiarities |
|---|---|---|
| LG OLED C1/C2 | Settings → Network → Wi-Fi | Quick switching in the curtain |
| LG NanoCell | All Settings → Network | Confirmation required |
| LG UHD 4K | Settings → All settings → Network | Standard webOS interface |

Hidden Features of the LG Network
LG TVs have a service menu accessible via a key combination on the remote control, but entering it without experience can reset the screen calibration. For a simple Wi-Fi disconnect, the standard menu is sufficient.
Disabling Wi-Fi on Sony Android TV and Google TV
Sony TVs use the stock Android TV operating system or its newer Google TV version. The shutdown process is as standardized as possible and is similar to the steps on a smartphone. Press the button Settings (gear) on the remote, then select Network and Internet (Network & Internet).
In the list that opens, find the item Wi-Fi. Switch the toggle switch to the position OffThe system will immediately disconnect. If you want to delete the network, click on your network name in the "Saved Networks" list and select Delete network or Forget.
A characteristic of Android TV is the presence of numerous background apps. Even with Wi-Fi disabled, some system services may attempt to use a wired connection (if a LAN cable is connected). Make sure the Ethernet cable is also disconnected if you want complete isolation.
On new Google TV models, the interface may hide the Wi-Fi switch in the upper right corner of the user profile screen. Tap the profile picture, and you'll see a network icon that you can quickly disable without diving into the deep settings menu.
Works with Philips and other brands of TVs
Philips TVs often run Android TV or their proprietary Saphi platform. For Android TV, the instructions are similar to those described above for Sony. If you have a Saphi model, press the button Menu or Home, then go to Configuration (gear).
Select Wireless networks or Network connectionsHere you can not only disable Wi-Fi, but also configure IP address settings. To disable it completely, select the option Turn off Wi-FiSome Philips models require a TV reboot after changing network settings for them to take effect.
For TVs from other brands, such as Xiaomi, TCL, or Haier, which are also often based on Android, the procedure remains the same: Settings → Network → Wi-Fi → OffIf the interface has been modified by the manufacturer, look for a globe or antenna icon in the top menu.
Alternative methods and physical disconnection
If disabling software is impossible or inconvenient, there are alternative methods. The most radical, yet effective, way is to change the router settings. By accessing the router's admin panel, you can find the list of connected clients (DHCP Client List), find your TV by MAC address, and block its internet access (Blacklist/Access Control).
Another method is to create a guest network. Configure your router so that the TV connects to the guest network, whose internet access is limited or completely blocked by firewall rules. This allows you to keep the local network (for DLNA, if needed) active, but blocks access to the external network.
Physically disabling the Wi-Fi module inside the TV is possible, but it's highly discouraged if the device is under warranty. This requires opening the case and disconnecting the antenna cable or the module itself. This method is only suitable for older models that you no longer plan to use as a Smart TV, but only as a monitor.
⚠️ Caution: Opening the TV case will void the warranty. Internal components contain high voltage even after unplugged. Please exercise caution.
To temporarily disable the internet, you can simply turn off the router, but this will cut off internet access for all other devices. A more elegant solution is to use smart plugs with a schedule that will turn off the router or TV at a set time, such as at night.
