How to update drivers on Xiaomi router: a complete guide with errors and solutions

Why updating Xiaomi router drivers isn’t what you think

When users are looking for ways to update drivers on Xiaomi routers, they often confuse two different processes: updating the firmware and updating drivers to run the router on the computer. In fact, Xiaomi routers do not have “drivers” in the usual sense, like printers or graphics cards.

1. Router firmware is firmware that manages all of the device’s functions (Wi-Fi, security, routing) and updates it to fix vulnerabilities, add new features, and improve stability.

2. Drivers for connecting to a PC – only if you connect the router to your computer via USB (for example, to configure in AP Mode or to firmware via MiWiFiRepairTool). 99% of the time they are installed automatically.

In this article, we’ll look at both scenarios: how to update the router’s firmware (which most users actually need) and how to install drivers for rare cases of manual PC connectivity. You’ll also learn why a firmware update via the Mi WiFi app can block the router if an unofficial version of the software is used.

When you really need to update the firmware of the Xiaomi router

The manufacturer regularly releases updates for its routers, but not all of them are critical.

• 🔌 The router spontaneously restarts or “hangs” (especially under load, for example, when torrenting or online games).
• 🔒 Security vulnerabilities: Xiaomi releases patches to close holes that hackers can exploit (e.g., vulnerabilities) CVE-2023-1234 in older versions of the firmware AX3600).
• 📶 Wi-Fi problems: low speed, connection breaks, inability to connect devices at 5 GHz.
• 🆕 New features: Wi-Fi support 6E, Mesh networks, parental controls or Mi Home integration.

If your router is stable, you don't have to update your firmware - the "don't break if it works" rule is appropriate here, but for models older than 2 years (such as the Mi Router 3G/4A), updates are critical due to outdated security protocols.

⚠️ Note: Updating the firmware on Xiaomi routers with modified software (such as Padavan or OpenWRT) can lead to the “bricking” of the device. If you installed custom firmware, use only compatible versions!

Ways to update the firmware of the Xiaomi router

There are three official ways to update the firmware, depending on the router model and the current version of the software:

For most users, the first or second method is optimal. Manual updates via a file (.bin or.tar) are recommended only in the event of critical failures or for installing alternative software.

💡

Updating via the web interface (192.168.31.1) is the most reliable way, since it does not depend on the work of Xiaomi servers and the Mi WiFi application.

Step-by-step instruction: update via web interface

This method works for all Xiaomi routers except models with very outdated firmware (until 2018).

1. Connect to the router's network via Wi-Fi or cable. Open your browser and enter 192.168.31.1 (or miwifi.com).
2. Enter your username and password (the default is admin and password from the sticker on the router). If it does not fit, reset the settings with the Reset button (hold 10 seconds).
3. Go to Status → Firmware Upgrade (or System Tools → Firmware Update in Russian).
4. Click Check for Updates. If an update is found, click Upgrade and wait until it is completed (the router will restart automatically).

The process takes 3-7 minutes. Do not turn off power or press the buttons on the router during the upgrade - this can cause a crash!

Backup your settings in System Tools → Backup/Restore|

Connect the router to the UPS (uninterruptible power source) |

Close all programs that use the Internet (torrents, online games) |

Make sure the firmware version is compatible with your model (check on the official website)

-->

⚠️ Warning: If the router doesn’t turn on or flashes orange after the upgrade, it’s a sign of firmware incompatibility. Restore the previous version via Fail-Safe mode (hold the Reset button when you turn on 15-20 seconds).

Update via Mi WiFi app: pitfalls

The Mi WiFi app (available for Android and iOS) makes it easier to manage your router, but has nuances:

• 📱 Requires a link to your Xiaomi account.If you are not logged in, the update will not be available.
• 🌐 It only works with a stable Internet connection, and if the speed is below 2 Mbps, the firmware download may be interrupted.
• 🔄 Sometimes offers beta versions of software that may be unstable. Disable the option to automatically install updates in the app settings.

Instructions for updating via Mi WiFi:

1. Open the application and connect to the router.
2. Go to the Device section → Firmware update.
3. If a new version is available, click Update and confirm the action.
4. Wait until the router is finished (the router will restart).

Problem: After upgrading via Mi WiFi, some users experience an error called "Device is disconnected from account" due to a sync failure with Xiaomi servers.

1. Reset the router to factory settings (Reset button).
2. Connect to it again through the app using the same Xiaomi account.
3. If the error repeats, update the firmware through the web interface.

Manual firmware update: for experienced users

If the automatic update doesn't work or you want to install a specific version of the firmware, you can do it manually. This method is risky - the wrong firmware file can knock the router out!

Instructions:

1. Download the firmware from the official Xiaomi website: For global versions of routers: mi.com/global/service/update For Chinese versions: mi.com/in/c/service/update (use translator)

Note the router model and region! The firmware file for the AX3600 won't work for the AX3000.

Unpack the archive (if it is in.zip or.rar format) – you should get a file with the.bin or.tar extension.

Go to the router web interface (192.168.31.1) and go to System Tools → Firmware Upgrade → Manual Upgrade.

Download the firmware file and press Upgrade. Confirm action.

Important: If the router does not turn on after manual updating, try to restore it through MiWiFiRepairTool (Windows utility). 4PDA Xiaomi Community.

💡

Before manually updating, check the checksum (MD5) of the downloaded firmware file, which must match the one listed on the Xiaomi website, which will protect against corrupted or fake files.

Update "drivers" to connect router to PC

As mentioned at the beginning of the article, Xiaomi routers do not require drivers in the traditional sense, but in two cases, additional files may be needed:

1. AP Mode (Access Point): If you connect a router to your PC over USB to configure as a repeater or bridge, Windows can request a driver for a network adapter.
2. Firmware via MiWiFiRepairTool: To restore a “brick” router, a special driver for Qualcomm Chipset (used in most Xiaomi models) is required.

If Windows does not recognize the router when connecting via USB:

1. Open Device Manager (Win + X → Device Manager).
2. Find a device with an exclamation point (usually in the Network Adapters or Other Devices section).
3. Right-click and select Update Driver → Automatic Search.
4. If it doesn’t work, download the driver manually from the Xiaomi website (Support → Downloads section for your model).

⚠️ Warning: Never download drivers for Xiaomi routers from third-party sites! fake files may contain viruses or spyware. Use only official sources: mi.com/global/support.

Frequent update errors and their solutions

Even when following the instructions, users encounter problems, and here are the most common errors and ways to correct them:

If none of these methods worked, please contact Xiaomi via chat in the Mi WiFi app or on the website. For routers, you can replace the device with warranties.

💡

The most common mistake is trying to install firmware from another router model. Always check the file name: it must contain the exact model (for example, the file name should be the same as the file name, miwifi_r3g_firmware_... for Mi Router 3G).
