How to update the firmware on the Xiaomi router: 3 proven ways

Updating the firmware on Xiaomi router is not just a manufacturer’s recommendation, but a necessary step to ensure stable network operation, protection from vulnerabilities and access to new features. With each update, Wi-Fi bugs are fixed, compatibility with modern devices is improved, and sometimes useful options like support for Mesh networks or advanced parental control settings are added. However, the update process can seem difficult, especially if you have never worked with the router’s admin panel before.

In this article, we’ll discuss three main ways to update your firmware: through the web interface (the easiest method), with the Mi Home app (comfortable for beginners), and manually (for power users when automatic updates are not available). Also, you’ll learn how to check the current version of the software, where to download official firmware and what to do if something goes wrong. Importantly, Xiaomi AX3600, AX6000 and RA75 routers require a special approach when manually updating due to the two-tier firmware system (bootloader + basic software).

1.Preparation for the update: what to do before the start

Before you start upgrading, make sure your router is ready for the procedure.Neglecting preparation can cause crashes, loss of settings, or even a "brick" of the device.

• 🔌 Stable power: connect the router to an uninterruptible power supply (UPS) or at least make sure there are no power surges on the network.
• 🌐 Backup: If you upgrade via a web interface, use an Ethernet cable instead of Wi-Fi.
• 📥 Free space: on routers with support USB-storage devices (e.g. Xiaomi) RA73) Make sure there is enough space on the flash drive for temporary files.
• ⏳ Time: Set aside 15-30 minutes for the process. Some firmware (especially for the process) AX6000) It takes longer to install due to file integrity checks.

Also, be sure to save the current settings.

1. Go to the router’s web interface (usually at 192.168.31.1 or miwifi.com).
2. Go to Settings → System → Backup / Restore.
3. Click Save Settings and download the file to your computer.

⚠️ Note: If your Xiaomi router was purchased outside of China (global version), do not install firmware for the Chinese market (CN ROM). This can result in feature blocking or incompatibility with local Wi-Fi standards.

2. Method 1: Update via web interface (recommended method)

This is the safest and easiest way for most users: the web interface automatically checks for updates and installs them without risking damage to the router. The instructions are relevant for the AX3600, AX1800, RA67 and others with official firmware.

Steps to update:

1. Connect your computer or smartphone to the router via cable or Wi-Fi.
2. Open your browser and type in 192.168.31.1 (or miwifi.com for some models).
3. Enter the login and password (by default – admin and password from the sticker on the router).
4. Go to Settings → Update firmware (or System → Update in new versions of the interface).
5. Click Check Updates. If the new version is available, click Update.
6. Wait until the process is completed (the router will restart automatically).

Update time depends on Internet speed and firmware size. For example, for the Xiaomi AX6000 file can weigh up to 50-70 MB, and for the RA73 - about 20-30 MB. If the update hung during the "File Check" stage, wait 10-15 minutes - sometimes the process takes longer because of the digital signature verification.

⚠️ Warning: If the router stopped handing out Wi-Fi after the upgrade or if it gives an error "No Internet access", try resetting to factory settings (Plug the Reset button for 10 seconds.

3. Method 2: Update via the Mi Home app

The Mi Home app (or Xiaomi Home for global versions) allows you to update your router’s firmware directly from your smartphone, a method that is convenient if you don’t have access to your computer or prefer to manage your devices via a mobile app.

• 📱 Not all models are supported (for example, AX6000 It may require manual file downloading).
• 🌍 The application must be the same regional version as the router (Chinese firmware is not updated through the global application).
• 🔄 Updates through Mi Home are sometimes lagging compared to the web interface.

Instructions for updating:

1. Open the Mi Home app and select your router from the device list.
2. Slip on the three dots in the upper right corner and select Settings of the device.
3. Scroll down and find the Firmware Update (or Firmware Update) section.
4. Click Check Updates. If a new version is available, follow the on-screen prompts.
5. Do not close the application or log out of your account until the process is complete.

If the application gives an error "I failed to connect to the router", try:

• Reconnect to the Wi-Fi router network.
• Restart the app and router.
• Make sure your smartphone is enabled with Bluetooth (some models require it for initial authorization).

💡

If there is no update button in Mi Home, check if the router is connected to your Xiaomi account. Go to Profile → My Devices and make sure the router is listed.

Method 3: Manual firmware update (for power users)

Handheld firmware will be needed if:

• 🔄 Automatic updates are not working (for example, due to a failure of Xiaomi servers).
• 📦 You want to revert to the previous version of the software.
• 🛠️ You need to install custom firmware (for example, OpenWRT or Padavan).

Manual updates will require:

1. Download the official firmware from the Xiaomi support site (choose a file for your model!).
2. Unpack the archive (usually a file with the.bin or.trx extension).
3. Download firmware via the web interface or via SSH (for advanced users).

Step-by-step instructions for downloading via the web interface:

1. Go to the router control panel (192.168.31.1).
2. Go to Settings → Firmware Update → Manual Update.
3. Click Select the file and specify the path to the downloaded firmware.
4. Confirm the installation and wait for the restart (it can take up to 10 minutes).

⚠️ Note: If you install firmware from another model (for example, trying to flash through) AX3600 file AX1800), The router will turn into a brick and will require restoration through the TFTP-server.

5. Where to download official firmware for Xiaomi

The official firmware for Xiaomi routers can be downloaded from three sources:

1. Xiaomi Support Site: Go to the support page. Type in the router model in search (e.g. AX6000). In the Downloads section, find the latest firmware version.
2. 4PDA Forums: The forum features firmware themes for all models, including betas. Pay attention to user feedback — sometimes new firmware contains bugs.

Telegram channels:

• Channels like @XiaomiRouter or @MiRouter are posting links to fresh firmware.
• Check the hash files (MD5 or SHA-256) before installing them!

Never download firmware from unknown sites – it may contain malicious code or be modified (e.g., with remote parental control) Official files always have a Xiaomi digital signature, which the router checks before installing.

💡

Download firmware only from official sources. Files from torrents or file sharing sites may contain backdoors for remote access to your network.

6. Frequent update errors and how to fix them

Even if you follow the instructions, you can make mistakes, and let's look at the most common ones and how to solve them.

If the router is unstable after the update (for example, breaks the connection or slows down), try:
