Network equipment owners often face situations where the only right solution is to return the device to its original state. Xiaomi Mi Router 4C router is no exception: a change of provider, a forgotten administrator password or a software failure require radical measures. Understanding the reset procedure is critical to restoring the health of your home network.
The zeroing procedure affects all user data, including PPPoE, Wi-Fi network settings and MAC-Before you start any manipulation, you have to realize that once you've finished the device, it will look like you just took it out of the box, which means completely removing all the configurations you've set before.
There are two main methods of doing this: physical (hardware) and software (web interface) and the choice of the specific method depends on whether you have access to the control panel of the router or access to the system lost. In both cases, the result will be identical, but the ways to achieve the goal differ significantly in complexity and required actions.
Preparation for the resetting procedure
Before you start taking action, make sure there is a stable power supply. Unstable voltage or accidental disconnection of the cord during the memory cleaning process can damage the device's file system. Make sure the Xiaomi 4C router is connected directly to the outlet, not to a network filter with a questionable history.
⚠️ Note: If you plan to use the router further with the same provider, find out the type of connection in advance and prepare a login / password from the Internet, since after resetting this data will be lost.
It is also worth preparing a computer or smartphone through which the configuration will be performed after the reboot. It is best to use a wired connection for the primary configuration, since it provides a more stable communication channel without the risk of losing data packets. wireless connection can be terminated at the most inopportune moment.
Check for the original power cable and make sure the lights on the device are working properly. If only the power indicator is on or a red light flashes, this may indicate more serious problems than just needing to reset, in which case the software methods may not work.
Hardware reset via Reset button
The most reliable and versatile way to return the Xiaomi Mi Router 4C to factory settings is to use a physical reset button.This method works even when the web interface is not available, the device is frozen or you do not remember the password to log in to the administration system.
On the back of the router, next to the LAN ports and the power connector, there is a small hole, signed as Reset, hidden inside it is a tactile button. To activate the reset mode, you need to use a thin object, such as an unbended clip, toothpick or a special needle that comes with the device.
The sequence of actions should be as follows:
- 🔌 Turn the router on the network and wait for the standard load to be completed (the indicators should be on even light).
- 📎 Insert a sharp object into the Reset hole and press the internal button before the characteristic click.
- ⏳ Hold the button in the pressed state for a period of time. 5-10 Seconds, watching the system indicator.
- 💡 Release the button when the status indicator flashes quickly in yellow or orange.
Once you release the button, the device will start the process of restarting and clearing the memory. This takes about 1-2 minutes. At this time, the router will be unavailable for connection, and the indicators can randomly switch. Do not try to turn off the power at this point.
☑️ Hardware reset checklist
It is important to note that some Xiaomi 4C revisions may have different button retention times. If nothing happens after 10 seconds, try increasing the retention time to 15-20 seconds. However, holding too long (over 30 seconds) in some versions can trigger Failsafe mode, which will require more complex firmware reflashing actions.
Reset via the web interface of the administrator
If you have access to the router control panel and you know the administrator password, you can do the reset software, which is more secure in terms of file system integrity, because the process is initiated by the operating system of the MIWiFi device itself.
First, you need to log in. Open any browser and enter it in the address bar. IP-Default router address: Xiaomi Mi Router 4C This is 192.168.31.1 or the domain name miwifi.com. Enter the administrator password you set when you first set up.
Follow the algorithm further:
- 🌐 Go to the Settings section (cog icon) in the upper right corner of the interface.
- 📂 Select Status or Status tab on the left menu.
- 🔄 Find the Reset or Factory Reset button at the bottom of the page.
- ✅ Confirm your actions in the pop-up window by agreeing to the data loss warning.
Xiaomi routers can be in Chinese or English, depending on the firmware version.Look for a button that says Reset or an icon that resembles a circular arrow. In the Chinese version of firmware, the reset button is often at the bottom of the status page and can be called.
What to do if the interface is in Chinese?
Once confirmed, the router will automatically restart. It takes no more than two minutes. Unlike a hardware reset, here you can see exactly that the command is received by the system, and the human factor associated with the duration of the button press is eliminated.
What happens to the data after the reset
A complete reset is a destructive operation that involves the memory partition where the user configuration is stored, and understanding what will be deleted will help you prepare for the network setup that follows without panic or time wasting.
Here is a list of data that will be permanently deleted:
- 📡 Internet Connection Settings (PPPoE, L2TP, PPTP, static IP).
- 📶 Parameters of wireless network (SSID Wi-Fi name, password, type of encryption).
- 🔐 Administrator password for logging into the web interface.
- 📋 Table of static IP-Port forwarding and port forwarding rules).
- 🛑 Parental Control and Blacklist settings MAC-address.
The only thing that is not usually affected by a standard reset is the version of the installed firmware, and if you have previously updated the router software, it will remain the same, but any changes made to the configuration files will be replaced by default values.
| Parameter | Before dumping. | After discharge (factory value) |
|---|---|---|
| IP-router | User-generated (e.g. 192.168.10.1) | 192.168.31.1 |
| Wi-Fi network name | Your name, for example, Home_WiFi) | Xiaomi_XXXX (passwordless) |
| Admin password | Absent (required creation) | |
| Mode of work | Router/Access Point | router |
One of the things that should be mentioned is the Mi Account binding, and in some cases, if a router is tightly tied to a Xiaomi cloud account, it may require the owner to be authorized to re-activate after a reset, a security feature that prevents the device from being stolen.
💡
Before resetting, take screenshots of the current WAN and LAN configuration so as not to re-search the technical data from the provider.
Primary adjustment after recovery
After successfully completing the reset procedure, Xiaomi router 4C It's going to be in a standby mode, and once the device boots up, it creates an open access point, and the name of the network will contain the router model and the last characters. MAC-addresses, for example, Xiaomi_4C_5A2B.
Connect to this network from your smartphone or laptop. Please note that there is no Wi-Fi password now, the connection will be unsecured. When you try to open any website in your browser, you will automatically be sent to the greeting page miwifi.com. If this does not happen, enter the address manually.
The initial setup process includes several stages:
- Selection of the interface language (Russian, English, Chinese available).
- Check the type of Internet connection (the router often determines the type, for example, PPPoE).
- Enter the login and password from the provider (if required).
- Setting a new name for your Wi-Fi network and creating a strong password.
- Set an administrator password to manage the router.
⚠️ Note: At the stage of creating an administrator password, the system may suggest using the same password as for Wi-Fi. To improve security, it is recommended to specify different combinations of characters.
During the setup, the router may suggest updating the firmware. If you just reset because of unstable work, updating the software is a highly desirable step, this will fix known bugs and close security vulnerabilities.
Solution and possible problems
Despite the simplicity of the procedure, users sometimes face difficulties. One of the most common problems is that the router does not respond to the Reset button. In this case, make sure you use a thin enough item. The hole in Xiaomi 4C is narrow, and standard toothpicks can be too thick without reaching the button.
Another common situation is that you can't connect to the router after reset, and the computer can give you an error called "No Internet access" or "Unidentified Network." This is normal, because the router is not yet configured to access the global network, as long as there is a local connection. Check that the computer network card is automatically received IP-address (DHCP).
If the web interface does not open at 192.168.31.1:
- 💻 Check it out. IP-Gateway address in the properties of your connection.
- 🔄 Try clearing your browser cache or using incognito mode.
- 🔌 Turn off mobile internet on your smartphone when configuring via Wi-Fi.
- 🛡️ Temporarily disable antivirus or firewall that can block local pages.
In the rare cases where a router goes into an endless bootloop cycle after a reset attempt, recovery via TFTP or UART may be required, a complex procedure that requires disassembly of the case and special equipment. However, for the Xiaomi Mi Router 4C, such cases are more the exception than the rule.
💡
If after resetting and reconfiguring the router continues to work unstable, the problem may not be in the software, but in hardware malfunction or overheating of the device.
