The situation when home Internet stops working stably, and the router refuses to give out Wi-Fi, is familiar to many owners of Xiaomi equipment. Often the only correct solution is a complete return to the original state of the device, which allows you to eliminate software failures, forgotten passwords and conflicts. IP-The owners of the Mi Router model 4A may be faced with the need for such a procedure after an unsuccessful firmware change or when transferring equipment to new users.
The process of restoring factory parameters on this device does not require a deep knowledge of network technologies, but requires carefulness and consistency. It is important to understand that there are two main methods of performing this operation: through the software interface of the web control panel and using a physical button on the body of the gadget. The choice of the specific method depends on whether you have access to the router settings or the device is completely locked.
Before you start taking action, you should evaluate the current state of your network equipment. If the web interface is available and you can log into the admin panel, you should use the software method, because it is more visible. However, if you forget the password from the Wi-Fi or admin, or the router stopped responding to queries, the only way out is to use the hardware reset via the recessed Reset button.
Preparation for the system recovery procedure
Any manipulation of the router's system files requires prior preparation to avoid losing important data. 4A does not store user files on internal memory in the usual sense, save the current PPPoE settings, static IP-addresses and DNS-It is recommended to pre-write data from your ISP, unless it is automatically linked to the Internet service provider. MAC-equipment address.
Particular attention should be paid to the power supply of the device during the process. Unstable voltage or accidental disconnection of the cord at the time of overwriting system files can lead to critical errors bootloader, after which the router will turn into a "brick". Make sure that the power cable is tightly inserted into the connector and the socket is good. It is also worth checking the integrity of the Ethernet cable that will be used to connect to the computer.
⚠️ Note: During the reset, all user data will be permanently deleted. This includes the names of Wi-Fi networks (SSID), Passwords, parental controls, and port forwarding, make sure you have backups of critical settings.
To complete the operation successfully, you will need access to any device with a web browser: a laptop, smartphone or tablet. If you plan to use a wireless connection, make sure that your device is connected to the router network, even if there is no Internet access through it. For a wired connection, prepare a patch cord that is guaranteed to be serviceable.

Method of software reset via web interface
The most secure and controlled way to return Xiaomi Mi Router 4A The way to do this is to use a built-in web interface to make it work, and you can visually validate the action and avoid random clicks. To start, open any browser on the connected device and type in the standard address bar. IP-The gateway address, which usually looks like 192.168.31.1 or the domain name miwifi.com.
Once you go to the address, the system will request authorization. Enter the administrator password you set when you first set up the router. If you didn't change it, try the standard one, but newer versions of the MiWiFi OS firmware often lock you without a password for security. Once in the main menu, find the partition responsible for the state of the system. Depending on the firmware version (Chinese or global), it can be called Status, Common Settings or System.
Inside the settings menu, you need to find System Status or System Status. Scroll down to the bottom of the page where the device state buttons are usually located. You need the option "Reset" or "Restore Factory Settings." The system can request a reconfirmation of the action, warning you of loss of all data. Press the corresponding button, and the router will begin the process of cleaning the memory.
Once confirmed, the devices automatically restart, and the display on the case will flash orange or yellow, which signals the flashing process configuration. At this point, it is strictly forbidden to pull the power cord. After 2-3 minutes, the router will restart, and you can connect to an open Wi-Fi network with a name containing the model of the device.
What to do if the web interface does not open?
Hardware reset button Reset on the body
If access to the software part is impossible due to a forgotten password or system freeze, the only solution is a physical reset. 4A, near-port LAN And the power connector, there's a small hole marked Reset, and you'll need a thin object to interact with it, like an unbended clip, a toothpick, or a special needle to handle it. SIM-map.
The procedure is done on the device on. Put the tool in the hole before a slight click, feeling the resistance of the button. Hold the button pressed. It is critical to maintain a time interval: it is usually necessary to hold the button for about 5-10 seconds until the status indicator begins to flash orange. If you release the button too early, the router will simply reboot without resetting the settings.
In some device revisions or firmware versions, the algorithm may differ: If the router is off, press the Reset button, then turn on the power and continue holding the button until the color of the indicator changes.This method is often used to flash the device through TFTP, but for a conventional reset, it can be relevant if the standard retention on the on device does not work.
⚠️ Warning: Do not use excessive force when pressing the Reset button. The mechanism of the button is miniature, and too much pressure can damage the board or the button itself, making it impossible to further control the device.
Once the indicator has changed color or blinked, release the button. The router will automatically start the cleanup procedure for NVRAM (energy-independent memory), where the user configurations are stored. The process takes a few minutes. Once completed, the device will restart, and the indicator will light up in blue (or yellow, depending on the model), signaling readiness for initial configuration.
Entrance to the control panel after reset
Once the reset is successfully completed, the router returns to the out-of-the-box state, which means it creates an open Wi-Fi hotspot. Xiaomi_ or MiWiFi_, You need a password at this point, open your browser, and you have to automatically redirect to the welcome page.
If no automatic redirection has occurred, manually type 192.168.31.1. The initial setting screen will open for you. The system will prompt you to select an interface language (if a multilingual firmware version is available) and accept the terms of the user agreement.
At the setup stage, you will be asked to create a new administrator password, remember this password or write it down in a safe place, as this is the one that will be used to log in to settings in the future. The Wi-Fi password will by default match the administrator password, unless you change this in the appropriate wireless network settings.
It is important to note that once reset, the router may not have access to the Internet until you enter your ISP’s data. If your ISP uses Dynamic IP (DHCP), the Internet will automatically appear immediately after connecting the WAN cable. If you use PPPoE (login and password) or static IP, you must manually enter the data in the appropriate settings wizard fields.
💡
Once reset and set up again, it is recommended to check the System Update section immediately. Often, Xiaomi 4A routers have older firmware versions that may contain security vulnerabilities or bugs that interfere with stable network operation.
Common Errors and How to Resolve Them
Despite the simplicity of the procedure, users may encounter a number of technical problems, one of the most common is that the router does not reset after holding the button, this may be due to sticking the button mechanism or features of a particular version of firmware, in which case try to repeat the procedure by increasing the hold time of the button to 15-20 seconds, or reset through the off state, as described earlier.
Another common problem is that you can't connect to the web interface even after you reset. Your computer can write "Without Internet access" or "Unidentified network." Make sure your PC's network adapter settings automatically receive it. IP-addresses DNS. Sometimes it helps to temporarily shut down the antivirus or firewall, which can block local access to the address 192.168.31.1.
It happens that after a reset, the router hangs on the orange indicator and does not go into configuration mode, this may indicate damage to system files or a failed previous update, in which case a deeper recovery procedure through TFTP may be required, which involves downloading a special firmware file to the computer and transferring it to the router at the time of boot.
| Problem. | Possible cause | Decision |
|---|---|---|
| The indicator burns orange. | No connection to WAN or software failure | Check the provider's cable, perform a reset |
| It does not open 192.168.31.1 | Incorrect IP or address conflict | Reset your network settings on your PC (cmd: ipconfig /release) |
| Reset button does not respond | Short retention time | Hold for more than 10 seconds before blinking |
| Forgot the administrator password | The human factor | Full Reset (Hard Reset) only |
💡
If, after all the reset attempts, the router continues to behave inadequately (cyclic reboot, heating), the problem may be hardware, in which case the software methods are powerless, and repair or replacement of the device is required.
Security settings after recovery
By bringing the Xiaomi Mi Router 4A back to factory settings, you have a clean sheet, but also an open door for potential threats. Standard security settings may not be strict enough for today's Internet. First, change the Wi-Fi network name (SSID) to a unique one so that neighbors don't get confused and try to get a password for a standard name.
Be sure to set a complex Wi-Fi password using a combination of different register letters, numbers and special characters. Avoid using personal data (dates of birth, phone numbers). In your wireless network settings, select WPA2-PSK or WPA3 encryption protocol if your devices support this standard. WEP and WPA protocols are considered outdated and easily hackable.
Remember to update the password to log in to the admin panel. By default, after reset, it may match the Wi-Fi password, which is not always convenient and secure. Create a separate, complex password to manage the router. It is also recommended to disable the WPS function, as it is one of the most vulnerable places in the protection of wireless networks.
For advanced users, it is recommended to enable a guest network for visitors, which will create an isolated segment of the network that does not have access to your main devices (computers, NAS, printers), regularly check the list of connected customers in the Mi Home application or web interface to detect unauthorized access in time.
