How to change the Wi-Fi password on the Xiaomi router: 3 working ways

Why Change Your Wi-Fi Password on Xiaomi and When You Need It

Xiaomi routers are some of the most popular home networking devices, thanks to their combination of price, performance and ease of setup. However, even the most reliable router requires periodic Wi-Fi password updates. Why does it matter?

First, by default, many Xiaomi models (such as the Mi Router 4A, AX3600 or AX6000) use standard password combinations that are easy to match through vulnerability databases. Second, if you have ever shared network access with guests, neighbors or colleagues, there is a high risk that your traffic is being used without your knowledge. Finally, changing your password regularly (every 3-6 months) is a simple security measure that protects against hacking through WPA2 or WPA3 protocol vulnerabilities.

When else should I change my password?

  • πŸ”„ You have noticed a suspicious decrease in Internet speed (possibly, outsiders have connected to your network).
  • πŸ“± On a smartphone or PC, notifications about new devices appeared on the local network.
  • πŸ”’ You bought a used Xiaomi router and are not sure if the previous owner reset the settings.
  • πŸ› οΈ After updating the router firmware (sometimes reset security settings).

In this article, we will discuss three official ways to change the Wi-Fi password on Xiaomi routers (including models with support for Mesh and Wi-Fi 6), and also tell you how to proceed if standard methods do not work.

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

The most convenient method is to use the proprietary Mi Wi-Fi app (formerly Mi Home), which is suitable for all modern Xiaomi routers, including the Mi Router 4A Gigabit Edition, AX1800 and AX5.

Step-by-step:

  1. Open the Mi Wi-Fi app on your smartphone (you can download it from Google Play or the App Store).
  2. Sign in with the same Xiaomi account that the router is attached to.
  3. On the home screen, tap your router icon (such as the Mi Router AX3600).
  4. Go to the Wi-Fi settings section (or Wi-Fi settings in English).
  5. Choose 2.4G or 5G (if you have a dual-band router).
  6. In the Wi-Fi Password field, enter a new combination (minimum 8 characters, it is recommended to use letters, numbers and special characters).
  7. Click Save and wait for the router to restart (it will take ~30 seconds).

⚠️ Note: If some devices (such as Yeelight smart bulbs or Mi Smart Speaker speakers) stop connecting to the network after changing the password, they will have to be reconnected. To do this, it is usually enough to reset the device settings (press the reset button for 5-10 seconds) and repeat the pairing procedure.

Method 2: Change passwords through web interface (192.168.31.1)

If the Mi Wi-Fi app doesn’t work (for example, due to an account sync error) or you prefer the classic method, you can use the web control panel. This method is universal and suitable for all Xiaomi models, including outdated ones (for example, Mi Router 3 or Mini).

Instructions:

  1. Connect your computer or smartphone to the Xiaomi router network via cable (LAN) or Wi-Fi.
  2. Open your browser (Chrome, Edge, Safari) and type in the address bar 192.168.31.1 or miwifi.com. Press Enter.
  3. Enter the login login and password. By default, it's: Login: admin Password: admin or the one you set earlier.

⚠️ Note: If a 404 error appears when you log in to the web interface or the page does not load, check:

  • πŸ”Œ Is the cable connected correctly? LAN (should go from the port WAN router to provider modem).
  • 🌐 Have you ever changed before? IP-router address (by default 192.168.31.1, but it can be changed in the settings).
  • πŸ”„ Does the antivirus or firewall block access to the local network.

What to do if you forget the password from the web interface?
If you don't remember the password to log into the router control panel, you'll have to do a full reset: 1. Find the Reset button on the back of the router (usually recessed in the case). 2. Take a paper clip or toothpick, press and hold the button 10–15 seconds until the indicators start flashing. 3. After restarting, the router will return to factory settings (login / password β€” admin/admin). ⚠️ All personal settings (including Wi-Fi password, guest network, and device priorities) will be deleted!

Method 3: Reset the router to factory settings (if nothing helps)

If you can’t log in to an application or web interface (for example, because of a password loss or firmware failure), the radical method is hardware reset, which will return the router to its original state, but will delete all settings, including:

  • πŸ” Wi-Fi (main and guest network) passwords).
  • πŸ“‘ PPPoE settings (if you have a login/password connection from the provider).
  • πŸ”„ Parental Control Rules and Device Priorities.
  • 🌐 Settings DNS, IPv6 port forwarding.

How to reset the Xiaomi router:

  1. Find the Reset button on the back (can be signed as WPS/Reset).
  2. Turn the router on and wait until it loads (the power indicator should burn evenly).
  3. Press and hold the Reset button for 10-15 seconds (until the indicators start flashing quickly).
  4. Release the button and wait for the reboot (it will take ~1-2 minutes).

After discharge:

  • πŸ“Ά The Wi-Fi network will be called the Xiaomi_XXXX (where XXXX β€” last-minute MAC-address).
  • πŸ”‘ The default password is indicated on the sticker under the router (or in the instructions).
  • πŸ–₯️ To set up, go to the web interface at the address 192.168.31.1 (login β€” admin/admin).

πŸ’‘

If the router does not distribute the Internet after reset, check the type of connection in the Internet section. For most providers in Russia (Rostelecom, Beeline, MTS), you need to choose Dynamic IP (Dynamic IP). If you have PPPoE, enter the login / password from the contract.

How to Create a Strong Password for Wi-Fi on Xiaomi

A weak password is one of the main reasons for home network hacking. To protect your Xiaomi router, follow the rules:

  • πŸ”’ Password length: at least 12 characters (optimum 16)+).
  • πŸ”€ Use a mixture of upper and lowercase letters, numbers and special characters (for example,!@#$%).
  • 🚫 Avoid obvious combinations: dates of birth, names, dictionary words, sequences (12345678, qwerty).
  • πŸ”„ Don’t use the same password for your Wi-Fi and Xiaomi account.

Examples of strong passwords:

  • Tr0ub4dour&3Xiaomi!
  • MiR0uter_AX3600#2026
  • W1F1_5ecur1ty@Xiaomi

πŸ’‘ Tip: To remember complex passwords, use password managers (like Bitwarden or KeePass) or write down your password on paper and store it in a safe place (but not on the router itself!).

πŸ’‘

Never share your Wi-Fi password via messengers or social networks. If you want to give a guest access, use the guest network feature in your router settings (limits speed and access to local devices).

Additional security settings for Xiaomi router

Changing your password is just the first step to protecting your network, and to make your Xiaomi router as secure as possible, we recommend you do a few more things:

  1. Update the firmware. Outdated versions of the software contain vulnerabilities. Check firmware relevance in Settings β†’ Software Update. If an update is available, install it.
  2. Turn off remote management. Some Xiaomi models have Internet access enabled by default. Turn off this feature in Settings β†’ Security β†’ Remote management.
  3. Turn on the filtering by MAC-This will only allow authorized devices to connect to the network. MAC-Addresses can be found in the settings of the router or on the labels of gadgets.
  4. Set up parental controls. Limit access to certain sites or set limits on children's Internet usage, which is available in Settings β†’ Parental Controls.

⚠️ Note: If you use a Xiaomi router in Mesh mode (for example, with Mi Mesh Wi-Fi), after changing the password on the main router, you will have to manually update the settings on all additional nodes.
