When wireless connections stop responding or the Internet is unstable, many users of budget equipment are familiar with the situation. Often the only effective solution is to completely return the device to its original state, which eliminates software errors and configuration conflicts. Owners of the Xiaomi Mi Router 4A model (including the Gigabit and 100M versions) often face the need for such a procedure after a change of provider or unsuccessful experimental settings.
Recovery of factory settings is a radical but necessary step to normalize network equipment, and it is important to understand that this process completely removes all user data, including Wi-Fi passwords, PPPoE settings and static data. IP-Once the procedure is complete, the router will behave as if you just took it out of the box and turned it on for the first time.
In this article, we will take a look at all the ways you can do this, using both physical controls and software interfaces, learn about the nuances of resetting for different firmware versions, and get answers to frequently asked questions. Follow the instructions carefully to avoid losing access to the administration panel.
Preparation for the recovery procedure: important nuances
Before you start to act, you need to make sure that the device is ready to manipulate. Physical access to the router housing is mandatory, since the main method of reset is tied to a mechanical button. Make sure that the device is connected to the power source and the indicators are on a level light, signaling the normal operation of the system.
If you have the ability to log in to the web interface, it is recommended to write down the current Internet connection settings in advance. Often users forget the username and password from the provider, and after reset, this data will be required to re-authorize on the network, write it down on paper or take screenshots so that you do not search for information in the contract at a critical time.
⚠️ Attention: During the reset, it is strictly not recommended to turn off the power of the router. Interrupting the recording of factory configurations can lead to a software failure, after which the device will turn into a “brick” and require complex flashing through the device. UART.
It is also worth preparing an Ethernet cable if you plan to set up the device through your computer after resetting.The wireless connection after the procedure will be opened or protected by the standard password specified on the sticker, which may not be secure at the time of initial setup.
Method of hardware reset via the Reset button
The most reliable and versatile way to bring the Xiaomi Mi Router 4A back to its original state is by using a hidden Reset button, which is located on the back of the case, usually next to LAN ports or power sockets, and you will need a thin object, such as an unbended clip or toothpick, to access it.
The algorithm requires accuracy and shutter speed. First, turn the router on and wait until the load is completed (about 1-2 minutes), then find a hole marked Reset and press inside until you click. Hold the button for 5-10 seconds while watching the system indicator.
☑️ Checklist before resetting the button
The key here is the LED light response, and when it flashes orange (or changes state quickly), the button can be released, and it signals that the system has taken a memory clearing command and started the recovery process, and if you release the button too early, it will not reset, and the router will continue to work as usual.
💡
If the indicator does not flash after 10 seconds of holding, try to increase the time of pressing to 15-20 seconds, but do not overdo it so as not to go into firmware recovery mode (Failsafe).
Once the button is released, the router will automatically restart, which can take a few minutes, while the device checks the integrity of the file system and applies standard configurations, and do not try to connect to Wi-Fi or the web muzzle in the first 60 seconds after turning on.
Resetting settings through the web interface of the administrator
If you have access to the control panel and know the administrator password, a software reset is a more convenient and secure option.It eliminates the risk of mechanical damage to contacts or an error in the time of holding the button. To log in, open your browser and go to 192.168.31.1 or miwifi.com.
The interface may vary depending on the firmware version (Chinese or global), but the logic remains similar. You need to find the partition responsible for the state of the system. In Chinese firmware, this is often the Common settings tab or Status tab, where the Restore factory settings button is located.
Click on the appropriate button and confirm your actions in the pop-up window. The system will warn you that all data will be deleted. Once confirmed, the router will reboot itself, which ensures that the configuration files are overwritten correctly, without the risk of interruption.
| Parameter | Default value (China) | Default value (Global) | Note |
|---|---|---|---|
| IP-address | 192.168.31.1 | 192.168.1.1 | Can change the user |
| Login admin | admin | admin | Often not required at first entrance |
| Wi-Fi password | Resetting completely | ||
| Network name (SSID) | Xiaomi_xxxx | Mi_4A_xxxx | Depends on the regional version |
In some versions of the firmware, the menu may be entirely in Chinese, so look for characters that mean "System" (usually the last tab with a gear) and a button with red text or a bin icon. Using an image translator on a smartphone can make navigation much easier.
Features of reset for Gigabit and 100M versions
The Xiaomi Mi Router 4A comes in two main versions: the 100 Mbps port and the Gigabit Edition. Although visually almost identical, the software and reset behavior can be different. The Gigabit version often comes with newer firmware versions where the interface can be changed.
In gigabit versions, button resets sometimes require longer retention times of up to 15 seconds, which is due to the bootloader's performance in newer hardware revisions. If the standard 5-7 seconds fail, increase the time you have to hit the Reset button.
It is also worth noting that once reset, the gigabit version can automatically try to update when it first connects to the Internet, which will take extra time, and the system indicator may burn yellow or orange before the updates are completed.
For both versions, the “clean setup” rule is relevant. After reset, it is recommended not to copy the old settings through the backup function if they were the problem, but rather to manually configure the router to prevent the transfer of erroneous configurations.
What to do if the router is not reset
There are times when standard methods don't work: the button doesn't respond, the web interface is unavailable, or the router goes into an endless reboot, and in such cases, more complex recovery techniques are required. First, try an alternative method of entering recovery mode.
Turn off the router. Press the Reset button and turn on the power without letting it go. Hold the button for about 10-15 seconds until a special indicator (often flashing yellow) appears, which will put the device in Failsafe or recovery mode. In this mode, you can try to reflash the device through TFTP or a special recovery tool.
⚠️ Warning: Recovery mode is for power users. Incorrect actions in this mode, such as downloading inappropriate firmware, can irreversibly damage the software part of the router.
If the button is physically broken or crashes, use the “30-30-30” method, although it does not always work for modern Xiaomi routers. The essence of the method is to keep Reset on for 30 seconds, then 30 seconds without power (without releasing the button), and another 30 seconds on. However, for Xiaomi 4A, a conventional reset with increased retention time is more effective.
The Secret Method for Advanced
In the case of software failures, where the router is working but the reset is not helping, the cause may be a flash memory, in which case only a complete flashing through official utilities will help, if the model is supported by the community or manufacturer.
Primary setting after returning to factory parameters
After a successful reset, the router will create an open Wi-Fi network with the name indicated on the sticker (for example, the router will create an open Wi-Fi network with the name indicated on the sticker, Xiaomi_xxx). Connect to it from your phone or computer, and the greeting window automatically opens, or you need to go to the address. 192.168.31.1.
The setup wizard will suggest you choose the type of connection. If you use PPPoE (often from Rostelecom, Dom.ru and other providers), you will need a login and password from the contract. IP (DHCP) The setting will occur automatically if the provider does not use the binding on the MAC-address.
Be sure to set a new administrator password and a strong password for the Wi-Fi network. Standard passwords are easily picked up by attackers. WPA2-PSK or WPA3 encryption is recommended if your devices support the new standard.
💡
After a reset, always change the default administrator password – a critical step for the security of your home network.
Once you have finished setting up, check the Internet speed and connection stability. If problems persist even after resetting and clean setup, it may not be the router, but the provider's cable or equipment on the service provider's side.
