How to Turn Off Xiaomi 4A Router

Many users are wondering about the correct termination of network equipment, and routers in the Redmi or Mi series are no exception. You can turn off the Xiaomi 4A router in several ways, each of which has its own characteristics and use cases. Understanding these differences will help avoid potential errors in network maintenance.

Unlike smartphones or computers, most routers don't have a "Complete Work" button in the conventional sense, because they're designed to run continuously. However, there are situations where you need to completely shut down your device, such as moving, cleaning from dust or diagnosing malfunctions, and we'll look at all the methods available, from simply removing the fork to software commands.

It is important to understand that improper disabling can damage the file system of the device, although modern Xiaomi models are quite resistant to such influences. However, adherence to a certain algorithm of actions will prolong the life of your gadget and ensure the stability of the home network in the future.

Physical power outage

The most obvious and common way to turn off the Xiaomi 4A router is to physically break the power chain. On the back of the device, next to the WAN port and LAN ports, there is a round connector for connecting the power supply.

If you have this switch on your firmware or body modification, you just need to move it to OFF. In this case, the device will stop consuming electricity, the indicators will go out, and the processor will complete all the ongoing operations. This is the safest method for regular use.

In cases where a mechanical switch is missing (which is often found in compact versions of the Mi Router 4A Gigabit Edition), the only option is to remove the plug from the socket or disconnect the cable from the socket.

⚠️ Warning: Never pull the power plug abruptly while actively downloading large files or updating firmware, this can cause damage to system files.

Physical shutdown is also necessary to clean the device of dust. Static electricity and heating contribute to the accumulation of debris inside the enclosure, so periodic full shutdown is useful for maintenance.

💡

Using a mechanical switch (if any) is preferable to pulling the plug, as this reduces the risk of sparking and damage to the power port.

Software reboot via web interface

A more civilized way, often confused with shutdown, is software reboot, and while the router won't go to sleep, it will correctly complete all the processes and start again, and you need to access the device control panel to do that.

Open any browser on a device connected to the router network and enter in the address bar IP-address: 192.168.31.1 or domain name miwifi.com. After entering the administrator password, you will be taken to the main settings menu.

• 🔹 Go to the Settings section (Settings).
• 🔹 Select the Status tab or System.
• 🔹 Find the Reboot button (Reboot).

After pressing the button, the system will warn that the connection will be interrupted. This is a normal situation. Xiaomi 4A router will turn off the radio modules, stop the processor and turn on again in 1-2 minutes. This method is recommended to use once a week to clean RAM.

Management through the Mi Wi-Fi mobile application

Smartphone owners can manage their network equipment remotely using the official Mi Wi-Fi app. This is handy when you're in another room or want to turn off the device without getting out of the couch.

Once you log in and link the router to your Mi Account, the main window displays the status of the device, and by clicking on the settings icon or going to the tool menu, you can find the reboot function. Like the web interface, it's not a full shutdown, it's a restart.

However, the app allows you to implement a “off” scenario by setting a schedule, so you can program the router to automatically restart or turn off Wi-Fi at certain times, such as at night, which helps save the device’s life and reduces the level of electromagnetic radiation in the bedroom.

Using Smart Sockets for Automation

For those who want to be able to completely turn off the Xiaomi 4A router remotely or on schedule, the ideal solution is a smart socket.

By plugging a router’s power supply into a smart socket (like the Xiaomi Mi Smart Plug), you have full control over the power supply. Using the Mi Home app, you can create a script that will physically shut down the device at a given time.

Screenplay: "Night"


Condition: Time 02:00




Action: Turn off the "Router" socket

This approach is useful not only for saving electricity, but also for protection against overheating in the summer, and the smart socket allows you to reboot the “hung” router remotely while on vacation, simply turning off and turn on power via the Internet.

* Average security is due to the risks of cyberattacks on IoT devices.** Low security due to the risk of damage to the port or file system in a sharp cliff.

Resetting to factory settings (Hard Reset)

Sometimes, by “turning off,” users mean wanting to return the device to its original state. If your Xiaomi 4A router is not working properly, a complete reset may be required. This procedure does not turn off the device permanently, but erases all user settings.

On the back, next to the ports, there is a small hole with the inscription Reset. To activate the function, you need to turn on the router, wait for the boot (about 1 minute) and press the button inside the hole with a paper clip.

• 🔸 Hold the button for less than 5 seconds to restart.
• 🔸 Hold the button more closely. 5-10 seconds before the System indicator flashes.
• 🔸 Release the button and wait for the process to complete (3-5 minute).

After that, the router will return to factory settings, reset the network name and password to the ones on the sticker at the bottom of the case, a last resort that should only be used in case of serious malfunctions.

⚠️ Note: Before performing the reset, be sure to write down the data from your ISP (login and password PPPoE), if they are required for connection, otherwise the Internet will not work.

Typical errors and precautions

When operating network equipment, users often make mistakes that shorten the life of the device, for example, frequent chaotic shutdowns and on without intervals can overheat the power cells and capacitors.

Another common mistake is using power supplies with inadequate specs.The Xiaomi 4A router requires a stable voltage, usually 12V. Using weak chargers from phones can cause unstable operation and cyclic reboots.

Also, keep in mind static electricity. Before touching the metal parts of the connectors or ports when the device is off, it is advisable to touch the grounded object to remove the static charge from the body.

💡

If the router gets too hot, let it cool off before turning on again.
