When a home network is no longer stable, it's familiar to many smart tech users: a device can freeze, lose a signal, or shut down the Internet, despite the service provider's health, and in such cases, often the only correct solution is to completely reset the router configuration, which brings the gadget back to the state in which it left the factory assembly line, removing all user changes.
Xiaomi Mi Router 4A is one of the most popular budget solutions on the market, but it is also prone to software failures. Sometimes the problem lies not in the hardware, but in the accumulated errors in the logical chains of the firmware. Resetting the settings of the Xiaomi 4A router completely removes the password from Wi-Fi and PPPoE authorization data, so this procedure must be prepared in advance to avoid being left without communication with the outside world.
In this guide, we will discuss in detail two main ways to recover: through the web interface and using a physical button on the case, you will learn about the nuances of working with Chinese and global versions of firmware, and also understand what to do if standard methods do not help.
Preparation for the recovery procedure
Before you start taking any drastic measures, you need to make sure you have all the information you need to set up, and once you run the factory reset command, the router becomes a blank slate, and you need to re-enter the data you receive from the provider, such as the login and password for the PPPoE or L2TP connection type, without which you will not be able to access the global network.
It is also critical to have access data on hand, if you have changed your standard wireless network name or administrator password, write down new values or be ready to use factory values. For the Mi Router 4A, standard data is often listed on a sticker at the bottom of the case, but many users change them for security reasons.
Make sure the device is connected to the power supply stable. Power surges during the configuration flashing process can damage the file system. It is best to use the original power supply and cable supplied with the kit. Check the integrity of the Ethernet cable if you plan to configure through a wired connection, as this is the most reliable way to communicate with the admin panel.
⚠️ Warning: Reset procedure is irreversible. All saved Wi-Fi passwords, Port Forwarding settings, static IP-The addresses and parental controls will be completely removed, and they can only be restored manually.
Hardware reset with the Reset button
The most versatile method, working even in cases where the web-interface is unavailable or the administrator password is forgotten. 4A And there's a little hole that's called Reset, and it's the one that's going to force you to go back to the original state, and you're going to need a thin object to do the surgery, a paper clip, a toothpick, or a special needle to reset. SIM-map.
Turn the router on and wait until it is loaded (the indicator should burn or blink normally). Find the Reset hole and press the button inside using a sharp object. Hold the button long enough - usually about 5-10 seconds. The indicators on the front panel can start flashing or going out, which signals the beginning of the memory cleanup process.
Do not release the button immediately after changing the display. Continue to hold it until the system indicator starts flashing orange (or blue, depending on the firmware version), which means successful start of the procedure. After that, the device automatically restarts. The whole process can take up to 2-3 minutes, during which time you should not turn off the power.
☑️ Checklist of hardware reset
Reset via web interface (Admin panel)
If you have access to your router settings and remember your administrator password, a software reset is a more convenient and secure option, it allows you to monitor the process and see the status of execution. To log into the control panel, open any browser on a device connected to the router's network and enter 192.168.31.1 or the domain miwifi.com in the address bar.
Once you log in (enter your administrator password), go to the settings section. Depending on the firmware version (Chinese or global), the interface may differ, but the logic remains the same. Find the Settings or Common Settings tab. In the menu on the left or in the center of the screen, look for Restore setting factories or Reset settings.
The system will request confirmation of actions, warning of loss of data, agreeing that you initiate a process that will take about a minute, the router will clean the configuration files and execute the rebuke. Unlike the mechanical method, it excludes the human factor associated with the retention time of the button.
⚠️ Note: If you use the Chinese version of firmware, the menu can be entirely in Chinese.Look for characters that match the word "Reset" (usually the last item on the bottom settings menu, often in red).

Features of Chinese and Global Versions
Xiaomi Mi Router 4A comes in two main versions: for the domestic market of China (CN Version) and for the global market (Global Version), the differences concern not only the interface language, but also the algorithms of some functions. Chinese versions often have more aggressive power saving settings and may require the installation of a special plug-in or application for full management.
In the global version, the menu is translated into English or Russian, which makes navigation much easier. The path to reset is standard: Settings → System Status → Restore factory settings. In Chinese firmware, the menu structure may be less intuitive for the European user. Often requires knowledge of basic characters or the use of an image translator on a smartphone.
It is important to note the difference in default domain names: Global versions can use miwifi.com, while Chinese ones are strictly tied to the domain name. IP-When trying to reset the Chinese version through the web interface without knowing the language, it is easy to press the wrong button, so the hardware method is often preferable for them.
| Characteristics | Chinese version (CN) | Global version (Global) | Version for RF/CIS |
|---|---|---|---|
| Interface language | Chinese (main), English | English, Russian, etc. | Russian, English |
| Access domain | 192.168.31.1 | miwifi.com | miwifi.com |
| Annex | Mi Wi-Fi (China region) | Mi Wi-Fi / Mi Home | Mi Home |

💡
Useful tip: Before buying a router, check the region version. Chinese routers are often cheaper, but require dancing with diamond when setting up and resetting, including the need to select the "China" region in the Mi Home app.
Post-reset setting
Once the reset is completed successfully, the router will create a new open Wi-Fi network. The network name usually contains the model name and unique characters, such as, Xiaomi_4A_XXXX. Connect to this network from your smartphone or laptop. The Master Setup window should automatically open).
Follow the instructions of the setup wizard. You will be asked to choose the type of Internet connection. If your ISP uses Dynamic IP (DHCP), the Internet will appear immediately after the cable is connected to the WAN port (blue port). PPPoE will need to enter the username and password from the contract. At this stage, a new Wi-Fi password and network name will also be set.
Remember to update the password login to the control system (admin). By default, after resetting the password may not be or it coincides with the password from Wi-Fi. Installing a unique administrator password will protect your network from unauthorized access and changes in settings by unauthorized persons.
⚠️ Warning: Do not confuse ports when connecting the ISP cable. The cable from the modem or from the entrance is always inserted into the blue port. WAN, Computers and TVs are connected to yellow ports. LAN.

Once reset, the router works like a new router. Don't be lazy to change the standard passwords immediately and check for firmware updates in the About System section.
Solving Frequent Problems
Sometimes users are faced with a situation where the router does not respond to the reset button or does not enter recovery mode. If the indicators do not change color with (long press), it may be the button stuck or the mechanism is damaged. In this case, try pressing the button a little stronger or, conversely, easier, varying the angle of the tool.
Another common problem is cyclic reboot after reset, where if the router is constantly blinking and does not go into access point mode, the firmware may be damaged, in which case it may be necessary to flash the device through TFTP or special recovery software, which is a more complex procedure.
If the web interface does not open at 192.168.31.1 after reset, check the network adapter settings on your computer. IP-address DNS Sometimes it helps to clear the browser cache or try to log in through incognito mode.
