The manufacturer’s modern Xiaomi Mi TV and Android TV Box smart TVs come with a variety of features to improve usability. One such technology is Wake on WiFi, which allows the device to exit sleep mode or be activated on a signal from the local network. This is convenient for voice control via a smartphone or integration into a smart home system, but often becomes a source of problems.
Users often experience a situation where the TV spontaneously turns on at night, does not go into deep sleep or consumes excess electricity, the reason for this is the active waiting mode of the network card, in this article we will discuss why this happens and how to properly deactivate this option for the stable operation of your equipment.
Disabling this feature does not affect the ability to view online content after manually turning on the device. However, this is guaranteed to prevent false positives and reduce the heating of the device when it is turned off. Let's look at the technical details of this protocol.
What is Wake on WiFi and why is it needed?
Wake on LAN (WoL), or Wake on WiFi (WoWLAN), was originally designed for remote computer management. In the context of Xiaomi TVs, this feature allows the network adapter to remain active in standby mode even when the main Android TV operating system is in sleep mode.
The main purpose of this technology is to be able to quickly start a device on command from a mobile application Google Home, Mi Home or remote with voice control. When you say "turn on the TV", the smartphone sends a magic packet through the router, and the TV responds to it by starting the system. Without an active WoWLAN, this scenario would not be possible, since the WiFi module would be completely de-energized.
However, the implementation of this feature in Xiaomi firmware is sometimes incorrect. the router can send service packets that the TV mistakenly interprets as a command to turn on. In addition, the constant activity of the radio module leads to increased power consumption, which is especially noticeable on models without a physical power switch.
⚠️ Note: On some models of Xiaomi TVs with PatchWall shell, disabling network functions may affect the operation of the “Translation” function from the phone to the screen off.
Understanding how it works helps us realize that we're not breaking functionality, we're just changing priorities: stability and energy saving versus remote wake-up. For most people who turn on a TV with a button on the remote, this option is redundant.
Diagnosis: Why the TV is turned on by itself
Before you make any changes to your settings, make sure that the problem lies in your network settings. There are several signs that Wake on WiFi is not working correctly or is in conflict with your router, and users often confuse this feature with other system processes.
Here are the main symptoms for which it is recommended to turn off network awakening:
- 📺 TV lights up with power indicator in the middle of the night for no apparent reason.
- 🔥 The body of the device is significantly heated, although it is visually turned off (black screen).
- 📉 Internet speed drops due to constant background TV requests.
- 🔄 The device does not go into deep sleep mode, but remains in the state of Ready".
It’s also worth checking whether the router itself is out of order. Some Keenetic, TP-Link, or Asus routers can send out broadcast packets to detect devices that Xiaomi TV perceives as triggers. If the problem comes back after a while after restarting the router, it’s precisely the interaction settings that matter.
It's important to distinguish between program sleep and shutdown. In sleep, Android continues to run in the background, update widgets and check email. This is where the WiFi adapter is active. If the TV is turned off through the Shutdown menu, the network module usually shuts down unless otherwise specified in the engineering menu.
Disconnection through the standard settings menu
The safest and most recommended way to manage power saving features is to use a standard Android TV or PatchWall interface. The interface may vary slightly depending on the version of the operating system and regional firmware, but the logic remains the same.
You first go to the main menu and find the settings section, and the way to do this is usually to click on the Settings button on the remote, then select Settings → Network and Internet. In some versions of the firmware, the desired item may be hidden in the About Device or Special Features section.
Inside the network settings section, look for a power saving item, which can be called Wake on LAN, Wake on WiFi, or simply Network Management, and if you find one, put it in the Off position, which will force you to turn off listening in sleep mode.
If you don’t find a direct switch in the standard menu, try the following:
- Go to Settings. → About the device.
- Find the Energy Savings or Eco-mode item.
- Turn off Quick Start. This is often automatically disables WoWLAN.
⚠️ Warning: After disabling the Quick Start feature, the TV may be on longer than usual (10-15 second, as the system will require full hardware initialization.
Remember to save the changes before leaving the menu. In some cases, the Xiaomi interface requires confirmation of action with the OK or Enter button on the remote. If the settings are reset after the reboot, a deeper intervention through ADB will be required.
Using ADB to force shutdown
Android’s customizations often hide advanced options from the average user, and if the GUI doesn’t work, you can use the Android Debug Bridge (ADB), a method that allows you to send commands directly to the system without the limitations of UI.
To connect, you'll need a computer (Windows, macOS or Linux) and a smartphone or tablet connected to the same WiFi network as the TV. First, allow debugging on the TV itself. Go to Settings → About device and quickly click on Build number 7 times.
Now in the developer settings menu (will appear in the main menu or in the "Advanced" section), turn on Debugging by USB (Debug over USB/Network). Remember. IP-The address of the TV that appears in the network status. On the computer, open the command line and enter the command to connect:
adb connect 192.168.1.XX:5555Where 192.168.1.XX — it IP-address of your Xiaomi TV. Once successfully connected, you can enter a command that prevents the system from using WiFi to wake up. The command can vary depending on the chipset (Amlogic, MediaTek), but the universal option for Android. TV:
adb shell settings put global wifi_sleep_policy 2You can also try to disable specific Google services that are responsible for cast protocols if they cause a wake-up call:
- 🔧 Disabled Network Sleep Policy.
- 🔧 Reset network settings via adb shell cmd netpolicy reset.
- 🔧 Disabling com.google.android.gms.cast.framework (requires caution).
⚠️ Attention: Use ADB-Incorrect commands can lead to unstable system operation or loss of network settings.
After completing the commands, be sure to reboot the TV completely through the menu or disconnect from the power grid for 1 minute, which is necessary to apply changes at the core level of the system.
Comparison of energy consumption regimes
Understanding the difference between modes of operation will help you choose the optimal balance between convenience and savings. Xiaomi TVs have several levels of power consumption, and Wake on WiFi directly affects the transition between them.
Below is a table showing the differences between the modes of operation of the network card and the system:
| Parameter | Active mode (Active) | Sleeping with WoWLAN (Eco Sleep) | Deep Sleep (Deep Sleep) | Shutdown (Shutdown) |
|---|---|---|---|---|
| State of WiFi | Full activity | Standby mode (Listening) | Unplugged. | Unplugged. |
| Reaction to remote control | Instant. | Instant. | 5-10 seconds delay | Full start (15+sec) |
| Consumption | High (>50 W) | Mean (3-5 watts) | Minimum (<1 W) | Zero (0 W) |
| Background processes | Everyone active. | System services | Absent. | Absent. |
As you can see from the table, WoWLAN Sleep consumes significantly more energy than deep sleep because of the need to maintain the radio channel. If your goal is maximum savings, you'd better use deep sleep or shut down completely.
☑️ Verification of energy saving settings
The mode of choice depends on the use scenarios, and if you use voice control often, you have to put up with a small amount of energy, and if the TV is used primarily for watching cable TV or flash drive movies, energy saving should be a priority.
Compatibility problems with routers and solutions
Often the root of the problem is not the TV, but the settings of the home router. IGMP Snooping or UPnP protocols can generate traffic that wakes up the TV, especially for networks with a large number of IoT devices.
Check your router's settings. Go to the router's web interface and find the Wireless section. Try disabling the guest WMM (Wi-Fi Multimedia) function or creating a separate 2.4GHz network exclusively for the smart home by isolating the TV.
Secret Codes of the Engineering Menu
You should also pay attention to WiFi channels. If the channel is congested, the TV may constantly try to reconnect or improve the signal, which keeps the module active. Switching to a static, less busy channel in the router settings can reduce the frequency of false awakenings.
In rare cases, it helps to update the firmware of the router. Manufacturers often release patches that fix errors with the multicast traffic that is used for Wake on LAN.
