2. Method 1: Hardware reset via Reset button

The most reliable and versatile method is a hard reset using a physical Reset button on the router’s body, which works even if you forget the password from the admin panel or the router does not respond to commands through the web interface.

The Reset button on the Xiaomi Router 4A is located on the back next to the power connector and is recessed in the case, so you will need a thin object to press - a paper clip, a toothpick or a special tool from the kit.

1. Turn the router on the network and wait for full load (the indicator should burn stably).

2. Find the Reset button on the back and hold it for 10-15 seconds.

3. Release the button when the indicators start flashing orange - this is a signal of a successful reset.

4. wait for the reboot (1-2 minutes) and configure the router again.

Important: Reset button retention time is critical. If you release it before 10 seconds, the router simply restarts without resetting. If you hold it longer than 20 seconds, the bootloader may be damaged, which will require a flashing through UART.

3. Method 2: Reset via web interface

If you have access to the router's admin panel, you can do a software reset without physical intervention, which is safer because it eliminates the risk of damage to the Reset button or failure due to unstable power.

💡

If after resetting through the web interface, the router does not issue IP-addresses (devices do not access the network), try manually to write a static computer IP ranged 192.168.31.x (For example, 192.168.31.100) and reset the settings.

4. Method 3: Reset via the Mi Home app
