How to change your password on Xiaomi Wi-Fi router via phone: full guide 2026

Why is it better to change your Wi-Fi password on Xiaomi via phone?

Changing the password on the Xiaomi router can be done in many ways, but using a smartphone is the most convenient and quick option. Unlike the web-based configuration, the Mi Wi-Fi mobile app (or Xiaomi Home for new models) offers an intuitive interface adapted to touch control. IP-Addresses and complex menus of the admin panel.

In addition, the app automatically detects your router model (Mi Router 4A, AX3600, Redmi Router AC2100, etc.) and adjusts the interface to its features. For example, for devices with Wi-Fi 6 support (like Xiaomi Router AX3000), additional security settings appear in the application, such as WPA3 or splitting networks into 2.4 GHz and 5 GHz. And also – you can change the password even without connecting to the router itself, if you have previously configured it through your Mi Account.

But there are nuances, too. For example, if you forget your Xiaomi account data, or you never tied your router to an app, you'll need to reset to the factory settings, and we'll talk about that -- and other pitfalls -- later.

What Xiaomi router models support changing your phone password?

Not all Xiaomi devices allow you to manage your Wi-Fi settings via a mobile app, here is the current list of supported models (as of 2026):

• 🔹 Mi Router 4A (including the Gigabit Edition)
• 🔹 Mi Router 4C and 4Q (budgetary options)
• 🔹 Mi Router AX1800 and AX3000 (Wi-Fi 6-enabled)
• 🔹 Redmi Router AC2100 and AX5
• 🔹 Xiaomi Router 4 Pro and AIoT Router AX3600

If your model is not listed, it doesn’t mean changing your phone password is impossible. For example, Mi Router 3G or older Mi Wi-Fi Mini versions may require a web interface (192.168.31.1). To see if your device is supported, check it in the compatibility list in Google Play or App Store for the Mi Wi-Fi app.

⚠️ Note: Xiaomi routers purchased outside of China (global versions) may have limited functionality in the app, for example, in some regions, the ability to manage via Mi Home is disabled - only through Mi Wi-Fi.

Also consider the firmware version. If your router hasn't been updated in a long time, some features in the application may not work. Check the relevance of the software in the Settings menu → Firmware update.

Preparing for a password change: what to do in advance

Before you change your password, follow a few simple steps to avoid problems:

1. Connect to the router network. Your phone must be connected to Wi-Fi, the password you're going to change, and if you forget your current password, you'll have to reset the router to factory settings (instruction below).
2. Make sure the router is on and running smoothly, and if the indicators flash red or the router is constantly rebooting, fix this problem first.
3. Update the Mi Wi-Fi app. Outdated versions may not support new router models or may contain bugs.

If you plan to change not only your password, but also your network name (SSID), write it down in advance, and after the change, all your devices will be disconnected from Wi-Fi, and you will have to reconnect them.

⚠️ Note: If you use a guest network on a router, its password changes separately. Once you change the main password, the guest network will remain with the same settings unless you manually change them.

Step-by-step: how to change the Wi-Fi password through the Mi Wi-Fi application

Follow this guide to quickly and securely change your password, as you’ve seen on the Mi Router 4A, but the steps are relevant for other supported models as well.

1. Open the Mi Wi-Fi app. If it's not installed, download it from Google Play or the App Store. Sign in with the same Xiaomi account that the router is attached to.

If you have a dual-band router (like the AX3000), you’ll have to change the password separately for 2.4 GHz and 5 GHz networks, and you can either leave the same password for both networks or you can set different ones, and that won’t affect performance.

For models with Mesh support (such as Xiaomi Mesh System), the process is similar, but the changes will apply to all nodes on the network at the same time.

How to reset your Xiaomi router if you forget your Wi-Fi password or account

If you don’t remember your current Wi-Fi password or your Xiaomi account, you’ll have to perform a hardware reset of the router, which will return all your factory settings, including your network name and password (usually a combination of numbers listed on the sticker on the bottom of the router).

Resetting instructions:

1. Find the Reset button on the router. It's located on the back and is often recessed in the case to avoid accidentally pressing. Use a paper clip or toothpick to press.
2. Press the button for 10-15 seconds. The indicators on the router will flash yellow or orange — this is a signal that the reset has begun.
3. Wait for the reboot. The router will reboot itself. 1–2 Then the factory-named network (Xiaomi_XXXX) It will appear in the list of available Wi-Fi.

After discharge:

• 🔄 Connect to the router network using the password from the sticker (usually 8 digits or admin type combination).
• 📱 Open the Mi Wi-Fi app and go through the initial setup as when you first connected.
• 🔐 Set a new password (see instructions in the previous section).

⚠️ Warning: Factory reset removes all user settings, including: Port Forwarding, Guest Network, Internet Access Schedule, Linked IoT devices (such as smart lamps or cameras) If you have important settings, you will have to reset them.

Xiaomi Router 4 Pro and AX3600 models may need to be re-assigned to your Mi Account after a reset. If you forget your account details, restore them to account.xiaomi.com.

Common mistakes and their solution

When you change your password through your phone, you often have typical problems, and here are the most common ones and how to fix them:

If some devices don’t connect to Wi-Fi after changing your password, try:

• 🔄 Restart router (turn off power for 30 seconds).
• 📱 Forget the network on the problem device and connect again.
• 🔐 Make sure that the new password is entered without errors (registrar is important!).

If the Xiaomi AX3000 router starts to turn off devices periodically after changing the password, check the Band Steering settings (automatic switching between 2.4G and 5G). In some firmware, this feature works unstable - disable it in Settings → Wi-Fi → More.

💡

If you often have connection problems after changing your password, try turning off the Smart Connect feature in your Wi-Fi settings. It automatically switches devices between 2.4G and 5G bands, sometimes resulting in communication breaks.

Additional security settings after changing password

Simply changing your password is not enough to protect your network completely. Here's what else you need to configure in the Mi Wi-Fi app:

• 🔒 Turn it on. WPA3. This security protocol is more reliable than WPA2. Find it in the Wi-Fi settings → Note: Some older devices (such as smart sockets) may not support WPA3.
• 🚫 Turn it off. WPS. This feature makes it easier to connect devices, but it's vulnerable to hacking. → Additionally. → WPS.
• 👤 Set up access control. Device management menus allow you to block unknown gadgets or restrict their access to the Internet on a schedule.
• 🌐 Create a guest network, which allows you to provide Wi-Fi access to guests without revealing your primary password. → Guest network.

For routers with support for Xiaomi Home (for example, AIoT Router AX3600), additional options are available:

• 🏠 Smart home integration: You can automatically turn off Wi-Fi on schedule or when everyone leaves.
• 🛡️ Protection against DDoS attacks. Included in Settings → Security → Protection from attacks.

If you have a router that supports OFDMA or MU-MIMO (like Redmi Router AX5), these technologies are already on by default and do not need to be configured further.

💡

When you change your password, be sure to update it on all smart home devices (lamps, cameras, sockets), many of which do not not notify you of the loss of communication, but stop working correctly.
