How to change the password on the router Xiaomi 4C: 3 proven ways

Xiaomi Router 4C remains a popular choice due to its price and functionality balance, but even experienced users sometimes have difficulty changing the Wi-Fi password. If you forget the current access code, want to update it for security or just transfer the router to a new owner, the password change procedure has its nuances. Unlike new Xiaomi models with the proprietary Mi Home application, 4C is managed through a classic web interface or Mi Wi-Fi utility, which causes confusion among those who are accustomed to modern solutions.

In this article, we will discuss all the current ways to change your password to Xiaomi 4C, including alternative methods for cases where standard login is not available. You will learn how to avoid common errors (for example, locking after incorrect input), what security settings should be checked further, and what to do if the router “does not see” new parameters.

Preparing for a password change: what you need to know in advance

Before you start changing your password, make sure you have:

• 🔌 Physical access to the router – required to reset settings or connect via cable.
• 📱 Device with network access (PC, smartphone or tablet) connected to Xiaomi 4C Wi-Fi or Ethernet.
• 🔐 Current login data – login and password of the admin panel (by default) admin/admin, unless changed).
• ⚡ Charger - if the router is powered by a battery (in rare modifications).

If you don't remember your current Wi-Fi password, but you have access to the admin panel, you won't have any problems — you can set the new code right in the settings. But if you lose data from the web interface, you will have to reset, which will return the router to factory settings. Xiaomi 4C does not support password recovery via email or SMS, like some modern models, so save a backup of settings in advance (if possible).

Method 1: Change password through the web interface (most reliable)

The classic method, which works on all firmware Xiaomi 4C. Suitable if you know the current username / password of the admin panel.

1. Connect the device (PC or smartphone) to the router via Ethernet cable or Wi-Fi. For reliability, we recommend using a wired connection - this will eliminate breaks when saving settings.
2. Open your browser and type in the address bar 192.168.31.1 or miwifi.com. If the page doesn't open, check the connection or try the alternative address 192.168.0.1.
3. Enter your login and password (admin for both fields by default). If the data has been changed, use the current ones.
4. Go to Settings → Wireless Mode (Wi-Fi) or Advanced → Wi-Fi (depending on the firmware version).
5. In the Wi-Fi Password field, enter a new code. We recommend using a combination of 8+ symbols with numbers, capital letters and special signs (for example, MiHome_2026!Net).
6. Press Save and wait for the router to restart (it will take 1-2 minutes).

Make sure the Password field is active (not grey)|

When you change your password, all devices will be disconnected from Wi-Fi. To connect again, find the network. Xiaomi_XXXX In the list of available and enter a new code. If the network does not appear, reboot the router with the power button.

💡

If the Internet is gone after changing your password, check the WAN settings in the Network section. The router may not be able to automatically connect to the provider.

Method 2: Using the Mi Wi-Fi app (for smartphones)

The official Mi Wi-Fi app (not to be confused with Mi Home!) lets you control the Xiaomi 4C router from a smartphone, but it doesn’t work on all firmware. If the web interface seems complicated, this method may be more convenient.

1. Download the Mi Wi-Fi app from Google Play or the App Store. Make sure you have the latest version.
2. Connect your smartphone to the network of the Xiaomi 4C router over Wi-Fi.
3. Launch the app and wait until it detects your router. If the device doesn't show up, click Add manually and enter the username/password of the admin panel.
4. Go to the Wi-Fi settings (or Wi-Fi Settings) section.
5. Enter a new password in the Network Password field and save the changes.

Mi Wi-Fi sometimes gives an error, "I couldn't connect to the router."

• 🔄 Reboot the router and smartphone.
• 📱 Make sure your phone is on Wi-Fi and offline VPN.
• 🔌 Try connecting to the router via cable (via the router) OTG-adapter).

Method 3: Reset the settings to the factory (if you forgot the password admin panel)

If you don't remember the login data to the web interface or app, the only way out is to completely reset. On Xiaomi 4C, this is done differently than on most routers: the Reset button works in two steps.

1. Find a small hole on the back of the router that says Reset.
2. Take a paper clip or toothpick and hold the button for 5-7 seconds until the indicators start flashing yellow.
3. Release the button and wait until the router restarts (it takes ~2 minutes) and all settings, including the Wi-Fi password, will be reset to factory.

Attention, after discharge:

• 🌐 The name of the network will return to the standard (Xiaomi_XXXX).
• 🔑 The Admin Panel Password will become Admin.
• ⚙️ All additional settings (port forwarding, parental controls) will be lost.

💡

On Xiaomi 4C, resetting the Reset button doesn’t always work the first time.If the indicators don’t blink, try holding the button for up to 10 seconds or turning off the router power for 30 seconds before trying again.

Common mistakes and their solutions

Even when you follow the instructions, you're going to have problems, and you're going to look at the typical situations and how you can fix them.

If the router after changing the password begins to “slow down” or lose the connection, check:

• 📶 Wi-Fi channel - in settings (Wireless mode) → Channel) select Auto or Manual Channel (e.g. 6 or 11 for 2.4 GHz).
• 🔄 Operating mode – if you use dual-band Wi-Fi, make sure both ranges (2.4 and 5 GHz) are enabled.
• 🛡️ Protection - only use it WPA2-PSK (not WEP or WPA3, which may not be supported by older devices).
