Why don't Mi Home devices automatically connect to a new Wi-Fi network?

Unlike smartphones or laptops, which remember multiple networks and switch automatically, Xiaomi smart home devices are linked to a single network at the firmware level.This is done for security reasons: this prevents attackers from connecting your camera to their router simply by knowing its MAC address.

When you change your router or network name (SSID), the following happens:

  • 🔌 The device loses connection to Xiaomi servers because it cannot find a saved network.
  • 📡 Even if the new network has the same name and password, Mi Home perceives it as different due to the change in the router's MAC address.
  • 🔄 Some devices (eg. Xiaomi Mi Robot Vacuum) can try to connect to the cloud via mobile Internet, but this works unstable.

Most problems arise with devices that:

  1. Connected directly to Wi-Fi (lamps, sockets, cameras).
  2. Use the protocol Mi Mesh (for example, sensors MiJia, which communicate through a gateway).
  3. Have outdated firmware (relevant for gadgets released before 2022).

💡 Important: If you simply changed your Wi-Fi password but the network name (SSID) remains the same, some devices may connect automatically after a reboot. However, this only works for models that support WPA3 and current firmware.

Preparing for a Wi-Fi upgrade: What to do before disabling your old network

To minimize problems, follow these steps to After you turn off your old router or change your network settings:

1. Update your device firmware via the app Mi Home:

- Open the tab Profile → Settings → Firmware Update.

- If there are any updates available, install them. This is especially important for gateways (Mi Gateway) and cameras.

2. Back up your settings:

- IN Mi Home go to Profile → Settings → Backup.

- Save the file to the cloud or locally. This won't preserve your Wi-Fi connection, but it will help you restore your automation scripts.

3. Check the compatibility of your new router:

  • ⚡ Supported standards: 802.11 b/g/n (Necessarily), 802.11ac (optional).
  • 📶 Frequencies: 2.4 GHz (main), 5 GHz (for new devices only).
  • 🔒 Encryption type: WPA2-PSK (recommended), WPA3 (not supported by all gadgets).

4. Write down the MAC addresses of critical devices (for example, gateways or cameras). They may be needed to connect to a new router via DHCP Reservation.

Common Wi-Fi Errors and How to Fix Them

Even with the right steps, users still encounter common issues. Let's look at the most common ones and their solutions:

1. The device does not find a new Wi-Fi network

  • 📵 Check that your router is broadcasting the network at the correct frequency 2.4 GHz (many devices Mi Home they don't see 5 GHz).
  • 🔄 Reboot your router and device.
  • 📡 Make sure the network name (SSID) does not contain Cyrillic characters or spaces—some devices do not support them.

2. Error Invalid Password when entering a password

  • 🔐 Check the case of the letters - the password is case-sensitive.
  • 📱 Switch the keyboard on your smartphone to the English layout.
  • 🔄 Try entering the password manually instead of using the clipboard.

3. The device connects, but immediately disconnects.

  1. That all devices in the scenario are online.
  2. That your region hasn't changed Mi Home (transition from China on Russia resets some settings).
  3. That the router settings do not block traffic to ports 80 And 443 (used to communicate with Xiaomi servers).

How to change Wi-Fi for devices with a gateway (Mi Gateway)

If you have a gateway Mi Gateway, the process of changing the Wi-Fi network becomes more complicated: the gateway itself must be reconfigured, and all sensors connected to it (motion, door opening, temperature) will automatically lose connection. Here's how to proceed:

1. Reconfigure the gateway:

- Open it. Mi Home, select the gateway and press Settings → Change Wi-Fi.

- Follow the instructions on the screen (you will need to press a button on the gateway).

2. Reset connected sensors:

- For sensors Mi Door/Window Sensor or Mi Motion Sensor Remove the battery for 10 seconds, then put it back.

- Wait until the gateway automatically finds them (the indicator on the gateway should flash blue).

3. Check the connection:

- Open in Mi Home list of devices connected to the gateway.

- If the sensor is displayed as Offline, click on it and select Add manually.

💡 Advice: If after changing the Wi-Fi gateway the operation is unstable (for example, the sensors are periodically disconnected), try:

  • 🔌 Connect the gateway to a power outlet via an uninterruptible power supply (UPS) - power surges can disrupt the connection.
  • 📡 Change the Wi-Fi channel in the router settings (for example, from Auto on 6 or 11).
  • 🔄 Update the gateway firmware to the latest version.
What to do if the gateway won't connect to a new Wi-Fi network
