In this article, we will look at all possible methods for disabling Wi-Fi on TVs. Doffler — from standard (via the settings menu) to advanced (using the service menu or physically disconnecting the antenna). We'll pay special attention to the nuances for different models: for example, on Doffler Smart 4K UHD (2022-2023) the algorithm differs from earlier versions Doffler Basic HDYou'll also learn how to check whether the module is truly deactivated and what to do if the TV "forgets" the settings after a reboot.

Before you begin, please note that some methods may affect the operation of other functions (for example, disabling Wi-Fi will block access to YouTube, Netflix and the branded app store Doffler App StoreIf your goal is simply to save bandwidth or limit children's internet access, consider alternatives: setting up parental controls or limiting the speed on your router.

1. Standard Wi-Fi shutdown via the settings menu

The most obvious and safest way is to delete the saved network or disable the module in the TV interface. This method works on all models. Doffler, except for the earliest versions (released before 2018), where the network menu is simplified. The instructions are valid for firmware versions 5.1.2 and above.

To turn off Wi-Fi:

If the service menu doesn't have the required options, try updating the firmware or using the method that physically disconnects the antenna (Section 5).

What to do if the service menu does not open?

If the combination Menu → 1 → 1 → 4 → 7 doesn't work, try alternative codes:

- For 2020-2021 models: Menu → 9 → 8 → 7 → 6

Furthermore, router blocking works even if the TV is connected to a guest network or using WPS. However, please note that some Smart TV features (e.g. voice search or weather update) may require internet access and will stop working.

5. Physically disconnecting the Wi-Fi module (extreme case)

If software methods do not help or you want completely eliminate the possibility of connecting to Wi-Fi (for example, to protect against data leakage), you can physically disconnect the module's antenna. This method is only suitable for users with experience in disassembling devices, as it requires opening the TV case and risks voiding the warranty.

Procedure:

1. Unplug the TV and wait until it cools down completely (10-15 minutes).
2. Remove the back cover by unscrewing the screws (usually they are hidden under rubber plugs).

5. If you need to completely deactivate the module, disconnect its cable from the motherboard.

After assembly, the TV will no longer detect wireless networks. Please note: on some models Doffler The Wi-Fi module is integrated into the main board, making physical disconnection impossible without soldering.

• 🌐 Connection test: Try opening any network application (eg. YouTube). If the error "No internet connection" appears, Wi-Fi has been successfully disabled.

If the TV still connects to the network, the following reasons may be true:

• The router has the function enabled WPS or Quick Connect, which automatically connects devices.
• In the settings Doffler activated Auto-connect to known networks.
• The settings were reset after a firmware update (applicable to models with automatic updates).

In such cases, repeat the disabling procedure or combine methods (for example, delete the network in the TV menu and add the MAC address to the router's blacklist).

⚠️ Attention: On some models Doffler After updating the firmware, the network may reconnect automatically, even if you've removed it. To avoid this, disable automatic updates in Settings → Support → Automatic software update.
