How to change the Wi-Fi password on the Xiaomi router: 3 ways + protection against hacking

Forgot your Wi-Fi password or want to put a more reliable one? Xiaomi routers (including the popular Mi Router 4A, AX3600 and AX6000 models) allow you to change the security key in a few minutes — through a mobile app, a web interface or even a voice assistant. But there are nuances: the wrong settings can lead to disconnecting all devices from the network or vulnerabilities for hackers.

In this article, 3 proven ways to change your password (including restoring access if you forgot the current one), a table with factory data for login and tips for choosing a reliable key. And a unique life hack for models with MiWiFi ROM 4.0+ firmware, which will speed up the process by 2 times.

If your Xiaomi router gives you an error when you log in to the settings or doesn’t save a new password, there’s a section at the end of the article that solves 90% of these problems.

1.Preparation: What to Know Before Changing Your Password

Before you change your password, check out three key points:

• 📶 Connect to the router: you must be on the same network with the device (via Wi-Fi or cable). If you forget your current password, use the factory reset (Reset button on the back panel).
• 🔧 Login data: by default login / password for the web interface — admin/admin (If you have changed it, use your data.
• 🔒 Type of encryption: Recommended WPA2-PSK or WPA3 (old standards WEP burglary).

On Xiaomi Mi Router 4C and later, you may need to confirm via Mi Home (if the router is linked to a Xiaomi account) if the app does not see the device, upgrade to the latest version or use the web interface.

2. Method 1: Change password through the Mi Wi-Fi (Mi Home) application

The easiest method is to use the official Mi Wi-Fi app (formerly Mi Home), which automatically defines the router model and offers an intuitive interface, and is suitable for all MiWiFi ROM-based devices (including the AX3600 and AX6000).

Step-by-step:

1. Open Mi Wi-Fi and make sure the router is connected to your Xiaomi account.
2. Go to the Wi-Fi settings section → Security settings.
3. In the Wi-Fi Password field, enter a new key (minimum 8 characters, with numbers and letters).
4. Click Save and wait for the router to restart (it will take ~30 seconds).

If the application gives an error "Can not save the settings" - check the Internet connection (the router must be online) or reboot it with the Power button.

Method 2: Web interface (192.168.31.1) - universal method

If the app doesn’t work or you have an old model (e.g. Mi Router 3G), use the web bar. login address is 192.168.31.1 or miwifi.com (if it doesn’t open, check the connection to the router).

Instructions:

1. Enter 192.168.31.1 in the browser and log in (login / default password, see the table below).
2. Go to Settings → Wi-Fi (or Advanced Settings → Wireless on English firmware).
3. In the Security section, select WPA2-PSK (or WPA3 if supported).
4. In the Password field, enter a new key and click Save.

On some firmware, after saving, the router will offer to update the DNS – agree, this will improve speed and security.

Method 3: Voice Assistant (for routers with AliGenie)

Xiaomi AIoT Router AX3600 and later support control via voice assistants (AliGenie, XiaoAI). This is the fastest way, but only works if the router is linked to the Mi Home account.

How to change your password with your voice:

1. Activate the voice assistant (e.g., say "Hi XiaoAI").
2. Say the command: "Change your Wi-Fi password to [new password]."
3. Confirm the action in the Mi Home application (push notification will come).

⚠️ Note: the voice method does not work if the password has special characters (for example, @ or.

💡

If the router does not respond to voice commands, update the firmware through Settings → Software update in the Mi Wi-Fi application.

5 How to create a strong password and protect yourself from hacking

A weak password is the main reason for a Wi-Fi breach, and hackers only need 10 minutes to pick up a key like 12345678 or qwerty.

• 🔐 Length: minimum 12 characters (optimally 16)+).
• 🔤 Difficulty: combination of capital, lowercase letters, numbers and special symbols (!@#$%).
• 🚫 Taboo: Do not use personal data (date of birth, pet name) or words from the dictionary.
• 🔄 Update: Change your password every 3-6 months.

An example of a strong password is T7#pL9@xK2$vR1!. To remember, write it down in a password manager (like Bitwarden or KeePass) or on paper (but don’t store it near the router!).

Additional protection:

• 🛡️ Turn it off. WPS In the router settings (this is a vulnerable protocol).
• 📡 Hide. SSID (network name, unless you want the router to be visible to everyone.
• 🔄 Enable Auto Update Firmware (System section) → Update).

💡

Never use default passwords (like admin or 12345678) - all hackers know them. Even simply replacing them with admin123! will increase security by 100 times.

6. Frequent errors and their solutions

If after changing the password, the Internet disappeared or the router does not save the settings, check these points:

⚠️ Note: if after changing the password, the Xiaomi router AX6000 Reset is constantly rebooted - reset it to factory settings (reset button for 10 seconds.

If the router gives an error "Impermissible password" - check if it has Cyrillic characters or spaces:!@#$%^&*()-_=+[]{};:'",.<>/?`~.

7. reset password if you forget the current

If you don't remember your Wi-Fi password and can't log in, you'll have to reset your router to factory settings, and all settings (including network name and guest access) will go back to default.

How to reset:

1. Find the Reset button on the back of the router (usually in the recess).
2. Take a paperclip or toothpick, press and hold the button for 10-15 seconds until the indicator starts flashing orange.
3. Release the button and wait for the reboot (2-3 minutes).
4. Connect to a network with a name Xiaomi_XXXX (password - from a sticker on the router).

On the AX3600 and later, after a reset, you may need to re-assign to your Xiaomi account via Mi Home.

⚠️ Note: on routers with Padavan firmware (alternative), resetting with the Reset button may not work. SSH: nvram erase && reboot
