Resetting the Xiaomi 4C router to factory settings: 3 proven ways

Xiaomi Router 4C is a popular network device with a balance of price and functionality, but even it sometimes requires a complete reset. You may have forgotten your Wi-Fi password, encountered an unstable connection, or plan to transfer the router to a new owner. In any case, resetting to factory settings will return the router to its original state, eliminating software failures and configuration conflicts.

The procedure seems simple, but it has nuances, from the choice of method (reset button, web bar or mobile application) to the consequences for stored data. In this article, three working reset methods, unique recommendations for recovery after the procedure and answers to frequent questions. If your Xiaomi 4C "gluts" or does not respond to settings, you are in the right place.

⚠️ Warning: Reset will delete all personal data, including network name (SSID), Wi-Fi password, attached devices in Mi Home and firewall rules. Save critical settings (e.g., ISP PPPoE settings) in advance or take a picture of the screen with the current configuration.

1.When do I need to reset the Xiaomi 4C router?

Don't rush to reset your router when you have the first problem, and most of the time, it helps to reboot or update your firmware, but there are situations where a hard reset becomes necessary:

• 🔒 The password from the administrator panel (192.168.31.1) or Wi-Fi is lost and cannot be restored.
• 🌀 Cyclical reboot: The router is constantly turned on/off without stable operation.
• 📡 Connection problems: Devices do not see the network despite the correct indicators on the case.
• 🛠️ Setting conflict after experimentation with DDNS, VPN or parental control.
• 📦 Preparation for sale/transfer: Clearing the personal data of the previous owner.

If the Xiaomi 4C router is just “slowing down” or periodically breaking the connection, try first:

1. Update the firmware through Settings → Update.
2. Change the Wi-Fi channel manually (for example, from a car to a 6 or 11).
3. Turn off the Smart Connect function (if double frequency is 2.4/5 GHz).

2. Method 1: Reset via Reset button (hardware method)

This is the most reliable way, because it doesn't depend on the state of the firmware or network settings. The Reset button on the Xiaomi Router 4C is located on the back, next to the power connector, and it's recessed in the case, so you'll need a sharp object (clip, toothpick).

Step-by-step:

1. Turn the router on (the power indicator should be blue or orange).
2. Find the Reset button and press it for 10-15 seconds (until the indicators start flashing yellow).
3. Release the button and wait for the reboot (1-2 minutes). Router will return to factory settings.

⚠️ Warning: If the indicators do not flash yellow after holding the button, it is possible that the contacts of the Reset button are contaminated or damaged, in which case try to repeat the procedure with great effort or use alternative methods (see section 3).

How do you know if the reset has been successful?

• 🔄 The router will restart automatically.
• 📶 The name of the Wi-Fi network will return to the standard: Xiaomi_XXXX (where XXXX is the last digit of the MAC- address).
• 🔒 The connection password will be reset to the factory (indicated on the sticker at the bottom of the device).

3. Method 2: Reset via web interface (if there is access to the panel)

If you remember the password from the admin panel, it's easier and safer, and it's suitable for a routine reset before selling or after a failed setup experiment.

Steps:

1. Connect your computer or smartphone to the router network (via Wi-Fi or LAN cable).
2. Open your browser and enter 192.168.31.1 (or miwifi.com).
3. Log in with a login and password (by default – admin and password from the sticker).
4. Go to Settings → Additional → Backup / Reset.
5. Click Reset settings and confirm the action.

⚠️ Warning: In some versions of the Xiaomi Router 4C firmware, the reset point may be in System Tools → Factory Restore. If the interface is in Chinese, use a translator or look for characters (factory reset).

💡

Before resetting via the web interface, save a backup of the settings (Backup button in the same menu) and this will allow you to quickly restore the configuration if the reset does not solve the problem.

What if you can’t get into the panel?

• 🔄 Restart your router and try again.
• 🌐 Check that you are connected to the correct network (not to the guest or repeater).
• 🔑 Make sure you use the correct password (look at the sticker on the bottom of the device).
• 📵 If IP- address 192.168.31.1 doesn't open, reset your browser cache or try another one (e.g. Firefox instead of Chrome).

Method 3: Reset via the Mi WiFi app (for smartphones)

The official Mi WiFi app (available for Android and iOS) allows you to control the router remotely, including resetting, which is convenient if you do not have access to a computer, but you have a smartphone connected to the Xiaomi 4C network.

Instructions:

1. Download and install the Mi WiFi app from Google Play or the App Store.
2. Connect your smartphone to the router’s Wi-Fi network.
3. Open the app and log in (use the data from your Xiaomi account if you have linked your device).
4. Select your Router 4C from the list of devices.
5. Go to Settings → General → Reset settings.
6. Confirm the action and wait for the reboot.

⚠️ Note: If the router does not appear in the app, check:

• 📶 Are you connected to its network (not the mobile Internet)?
• 🔄 Is the router firmware updated (older versions may not support remote management).
• 🔒 Does not block firewall or antivirus on your smartphone from accessing your local network?

Possible errors and their solutions

Even if you do the right thing, the reset can go wrong, so let's look at the typical problems and how to fix them.

1.The router is not reset via the Reset button

• 🔌 Check the power: the indicator should burn (if not, replace the power supply).
• ⏱️ Hold the button for longer than 15 seconds (sometimes it takes up to 20 seconds).
• 🛠️ If the button is not pressed, clean it gently with alcohol.

2.After reset, the router does not give away Wi-Fi

• 🔄 Wait for the full load (up to 3 minutes).
• 📡 Check that the Wi-Fi indicator is green (if not, press the Wi-Fi button on the case).
• 🔌 Reconnect the internet cable (Perhaps WAN settings are lost).

3.The web interface is not available after reset

• 🌐 Make sure you are connected to Xiaomi_XXXX (not another network).
• 🔒 Try the standard password from the sticker (sometimes the reset doesn't return all settings).
• 📵 Reset your browser cache or use Incognito mode.

💡

If the router does not give IP- addresses after reset (DHCP does not work), manually assign IP from the 192.168.31.X range (for example, 192.168.31.100) with a 255.255.255.0 mask and a 192.168.31.1 gateway to the computer.

6.Router Restore after Reset

After a successful reset, the Xiaomi Router 4C will return to factory settings. To return it to working condition, perform a basic setup:

Step 1: Connect to the Internet

• 📡 Connect the provider's cable to the port WAN (usually highlighted in blue).
• 🔑 If you use PPPoE (for example, Rostelecom or Beeline), enter the username / password from the provider in the web interface (Settings → Internet).
• 🌀 No additional settings are required for Dynamic IP (DHCP.

Step 2: Set up Wi-Fi

• 🔒 Set a new network name (SSID) and a strong password (recommended WPA2-PSK).
• 📶 Select a channel manually (e.g. 6 for 2.4GHz) if automatic selection is not stable.
• 🛡️ Disable WPS (security vulnerability) in Settings → Wi-Fi.

Step 3: Update the firmware

• 🔄 Go to Settings → Update and install the latest version of the software.
• ⚠️ Do not interrupt the update process – this may result in a device being knocked out.

Step 4: Additional settings (optional)

• 👨‍👩‍👧‍👦 Set up Parental Controls to restrict access.
• 🔗 Enable Guest Network if you need a separate access point for visitors.
• 📊 Activate QoS to prioritize traffic (e.g., streaming or gaming).

💡

After reset, it is recommended to change the password from the Administrator Panel (192.168.31.1) to a more complex one than the standard one. Use a combination of letters, numbers and characters (for example, Xiaomi@4C_2026!).

7. Alternative Resetting Methods (for experienced users)

If the standard methods don't work, you can try more complex ones, they require technical skills and are used in extreme cases.

1. Discharge via Telnet/SSH

Some Xiaomi Router 4C firmware allows you to connect via SSH and perform a reset command:

nvram erase


reboot

⚠️ Warning: This method requires SSH- access enabled (defaulted) and may cause the router to fail if the commands fail.

Manual flashing

If the router is “bricked” (does not turn on or flashes orange), the firmware via TFTP will help:

1. Download the official firmware for Xiaomi Router 4C from the Xiaomi website.
2. Connect the router to the computer by LAN-cable.
3. Set up a static IP 192.168.31.2 with a 255.255.255.0 mask on your PC.
4. Run a TFTP- server (e.g., Tftpd64) and specify the path to the firmware file.
5. Turn on the router with the Reset button clamped – it will automatically download the firmware.

🔹 Important: This method is risky -- if you make a mistake, the router can permanently fail. Use it only if other methods have not worked.
