Changing internet providers, upgrading routers, or even simply moving to a new apartment often necessitates reconfiguring the entire smart home ecosystem. Users often encounter a situation where MiHome app The network stops detecting devices because they're tied to the old network. Changing network settings isn't just a simple password reset, but a complex resynchronization process that requires consistent steps.
It is important to understand that Xiaomi uses a specific communication protocol that depends on the stability of the connection. If you simply changed the router, leaving the name and password the same, most devices will connect automatically. However, if the SSID (network name) or security settings have changed, manual intervention will be required for each device. In this article, we'll cover a detailed procedure for various scenarios.
Critical: ZigBee and Bluetooth devices do not change Wi-Fi settings directly, as they connect through a gateway, and it is the gateway itself that needs to be reconfigured. This is a common mistake when users try to reset motion or temperature sensors, which is completely useless for changing networks. Always check your device's connection type first.
Preparing the infrastructure before setup
Before you begin using the app, you need to make sure your network infrastructure is ready to work with smart devices. Most gadgets Xiaomi Work exclusively in the 2.4 GHz band. If your new router combines the 2.4 and 5 GHz bands under one name (the Smart Connect feature), you may experience initial pairing issues.
To ensure successful synchronization, it's recommended to temporarily separate the networks or force the smartphone to switch to 2.4 GHz. Also, make sure AP Isolation isn't enabled on your router, which blocks devices from communicating within the local network. Without this step, local control will be unavailable.
- 📶 Make sure your router is broadcasting a 2.4 GHz network and that it is active.
- 🔒 Check the encryption type: it must be WPA2-PSK (AES), older types may not be supported.
- 📱 Install the latest version of the app Mi Home from the official store.
⚠️ Important: If you're using a mesh system, make sure all nodes are properly synchronized. Some older smart home devices may become lost when switching between mesh network satellites.
Script for changing the password or network name (SSID)
If you've changed your router settings but the hardware remains the same, restoring the connection is the simplest. In this case, you don't need to delete the devices from the app. Simply adjust the router settings to match the devices' "remembered" settings or reconnect them through the device menu.
Go to the specific device card in the app. Tap the three dots in the upper right corner to access the settings menu. Find the item Device Settings or Wi-FiIf your device supports changing networks without a reset, you'll see a "Change Wi-Fi" button.
However, most often, a hard reset is required. Press and hold the physical button on the device (or use a combination of buttons, such as pressing two buttons on a switch simultaneously) for 5-10 seconds. The indicator light should flash orange, indicating pairing mode.
The procedure for adding a device again
After putting the device into pairing mode, you need to add it as a new one. In the main menu of the application Mi Home Click the plus sign in the upper right corner. The app will automatically scan the network. If the device is found, click "Connect."
If the automatic search fails, select your device from the category list or search by model. Follow the on-screen instructions: select your Wi-Fi network from the list and enter the password. Your phone must be connected to the network you want to pair it to.
The data transfer process may take 10 to 60 seconds. During this time, keep your smartphone screen open and keep the device close to the router. Once successfully connected, assign a name to the device and select a room for easy control via voice assistants.

Features of setting up ZigBee Wi-Fi gateways
Gateways act as a bridge between your router and ZigBee devices, such as door sensors, temperature sensors, or wireless switches. The gateway requires Wi-Fi configuration, and child devices connect to it automatically.
When changing networks, the gateway is reconfigured first. After the gateway (usually a cube, round base, or multimode gateway) connects to the new Wi-Fi network, it will automatically search for its slave devices. This may take several minutes.
If the sensors don't automatically reconnect, a brief reset of the sensors will be required. To do this, press the sensor button once (or three times, depending on the model) to wake it from sleep mode and attempt to find the gateway. The device status in the app will change from "Offline" to "Online."
What should I do if the gateway doesn't see sensors after changing the network?
If the gateway is connected to the internet but the sensors are offline, try bringing the sensor close to the gateway (10-20 cm) and activating it. Sometimes you may need to delete the sensor from the app and add it again, but only after successfully reconfiguring the gateway itself.
5GHz and roaming issues
A common problem is trying to connect a device to a 5 GHz network it doesn't support. Modern routers often mask this by creating a single network. If the connection freezes at 99% or the device isn't detected, the problem is almost certainly related to the frequency band.
The solution is to temporarily disable the 5 GHz band in the router settings or create a separate guest network using only the 2.4 GHz protocol. After the device is linked, you can restore the router settings, but make sure the network names (SSIDs) for 2.4 and 5 GHz are different to prevent the smartphone from switching to 5 GHz during setup.
The roaming feature (802.11r/k/v) is also worth mentioning. It's often unnecessary for a smart home. IoT devices can't quickly switch between access points, which leads to connection drops. If you have a complex network, try disabling fast roaming for the area where your devices are located.
⚠️ Note: The app interface and router settings layout may vary depending on the firmware version and hardware model. Always consult your router manufacturer's latest documentation.
Diagnosing and troubleshooting connection errors
If your device constantly shows as "Offline" or periodically loses connection, check your signal strength. Devices Xiaomi have weak antennas compared to smartphones. Walls, mirrors, and household appliances can block the signal.
Use the table below to quickly diagnose common network switching errors:
| Symptom | Possible cause | Solution |
|---|---|---|
| The device was not found during the search. | Pairing mode is not activated | Perform a full reset using the button until the indicator flashes. |
| Error at stage 99% | Incorrect password or 5GHz band | Double-check your password and force-enable 2.4 GHz on your phone. |
| The device is online but not controlled. | DNS or server issues | Change the DNS in the router to 8.8.8.8 or 1.1.1.1 |
| Constant disconnections | Weak signal or interference | Install a repeater or move the device closer to the router |
In some cases, clearing the app cache helps. Mi HomeGo to your smartphone's settings, find the app, and select "Clear Cache." This won't delete your devices, but it may fix status display issues.
Questions and Answers (FAQ)
Do I need to reset all my devices again when I change my router?
No, not all. If you leave the network name (SSID) and password exactly the same as on the old router, most devices will connect automatically. A reset is only required if network settings have changed or devices have "remembered" the old router and cannot switch.
Is it possible to change the region in the app without losing devices?
Unfortunately, no. Changing the region in your profile settings Mi Home (For example, from "Russia" to "China"), the device list in the main menu will become empty. You'll have to relink all your devices, as they are stored on servers specific to a specific region.
Why does the device say "too far from the router" during setup?
This message often indicates poor signal quality or the use of the 5 GHz band, rather than physical distance. Move your phone and device closer to the router during setup. Also, make sure your phone's mobile data connection is disabled while transferring data.
How do I change Wi-Fi on a device that is currently in another country?
It's not possible to remotely change the Wi-Fi network on a smart home device, as changing settings requires local interaction. The device must be within range of the new network to accept the new credentials. You'll need physical access to the device.
