Xiaomi Repetitors (or Wi-Fi repeaters) are compact devices that help amplify wireless signal in places where the router “does not reach” and you can set up such a gadget in literally 5-10 minutes using only a smartphone and the proprietary Mi Wi-Fi application. But even in this simple process, there are nuances: from choosing the optimal location of the repeater to the correct connection to the main network.
Many users face common mistakes: the device does not connect to the router, flashes a red indicator or creates a separate network instead of strengthening the existing one. In this article, we will analyze the step-by-step configuration of the Xiaomi repeater via the phone, consider the models Mi Wi-Fi Repeater 2, Mi Wi-Fi Repeater Pro and Xiaomi AIoT Router. AX3600 (in repeater mode), and also give advice on eliminating common problems.
If you've never set up network equipment before, don't worry. It's as automated as possible, and you can pick up all the complex things (like Wi-Fi channels or encryption types) on your own, and you can follow the instructions and not skip the steps.
What Xiaomi Repeaters Can Be Configured Through Your Phone
Xiaomi has several models of signal repeaters, all of which support smartphone tuning.
- 📶 Mi Wi-Fi Repeater 2 - budget model with support for Wi-Fi 4 (802.11n), Maximum speed of up to 300 Mbps is ideal for small apartments.
- 🚀 Mi Wi-Fi Repeater Pro - improved version with Wi-Fi 5 (802.11ac), speed up to 1200 Mbps and support MU-MIMO.
- 🌐 Xiaomi AIoT Router AX3600 — Full-fledged router, but it can be used as a repeater in the mode "Network amplifier».
- 🔄 Xiaomi Mi Wi-Fi Range Extender AC1200 — model with two antennas and dual range support (2.4 GHz) + 5 GHz).
All of these devices are configured via the official Mi Wi-Fi app (formerly Mi Home), available for Android and iOS. The main difference between the models is in supported Wi-Fi standards and top speed. For example, if your main router is running at 5 GHz, then Mi Wi-Fi Repeater 2 will not be able to amplify this signal (it only supports 2.4 GHz).
Before buying, check which Wi-Fi standard your router uses.This information is usually listed on a sticker on the back of the device or in the web interface (in the Wireless Network section).
Preparation for setting up: what to do before connecting
Before you start setting up, follow a few simple steps to avoid errors and save time:
- Place the repeater in the zone of a confident signal. The optimal distance from the router is 5-10 meters. If you put the repeater too far, it will catch the weak signal and amplify it with loss.
- Connect the repeater to the socket. Make sure the power indicator lights up in blue or orange (depending on the model).
- Install Mi Wi-Fi. Download it from the App Store or Google Play. Older versions of the app (such as Mi Home) may not support newer repeater models.
- Turn it off. VPN They can block the connection to the repeater during the setup.
We also recommend you update your repeater firmware to the latest version. To do this, after connecting to it, go to the Mi Wi-Fi app and check for updates in the Device section. → Update of the PO.
⚠️ Note: If your router is using WPA3-encryption, some models of Xiaomi repeaters (for example, Mi Wi-Fi Repeater 2) may not connect to the network. WPA2-PSK attunement.

Step-by-step setting up the Xiaomi repeater via phone
Now, the connection process itself, which is universal for all Xiaomi repeater models, but there may be minor differences in the interface of the app.
Step 1: Connecting your phone to a repeater network
1. Turn the repeater into the socket and wait for the indicator to flash orange (setting mode).
2. On the phone, open Settings. → Wi-Fi and find a network called Xiaomi_XXXX or MiRepeater_XXXX (where XXXX — unique identifier of the device).
3. Connect to this network. No password required.
If the network doesn't appear, try:
- 🔄 Reboot the repeater (take out and insert back into the socket).
- 📱 Reboot the phone or turn on/off the aircraft mode.
- 📡 Check if the antivirus is blocking the connection to new networks.
Step 2: Launching the Mi Wi-Fi app
1. Open the Mi Wi-Fi app and click Add Device (Icon) + top-right).
2. Select Repiter or Network Amplifier category (depending on the application version).
3. Follow the instructions on the screen. The app will automatically determine your repeater's model.
At this point, you may be asked to access your location, which is necessary to scan the available Wi-Fi networks. Allow access.
Step 3: Selecting a Main Network to Strengthen
1.The application will offer a list of available Wi-Fi networks. Select the one you want to strengthen (it should match the network of your main router).
2. Enter the password from this network. Make sure that you specify the password from the router, not from the repeater.
3. Click Next and wait for the connection. This process can take up to 1-2 minutes.
If the repeater is not connected to the network, check:
- 🔑 Correctness of the password entered (registrar matters!).
- 📶 The signal level of the main network at the location of the repeater (should be at least 2-3 divisions).
- 🔄 Wi-Fi compatibility (e.g. Mi Wi-Fi Repeater 2 does not support 5GHz).
Step 4: Set up repeater parameters
After successful connection, the application will offer:
- Name of the network (SSID). By default, the repeater will use the same name as the main router, but with a suffix _EXT. You can change it or leave it as it is.
- You can leave the same password as the main network, or you can create a new one.
- Select Repeat Mode (if you have a choice).
Press Save and wait for the repeater to restart. After that, the indicator should light up blue (successful connection) or green (in some models).
⚠️ Note: If you change the name of the network (SSID) If you move between the coverage areas of the router and the repeater, the devices (phone, laptop) will not automatically reconnect. For seamless roaming, leave the network name the same as the router.
💡
For maximum speed, place the repeater half the distance between the router and the "dead zone." For example, if the router is in the hallway and the signal does not reach the balcony (10 meters), place the repeater at a distance of 5 meters from the router.
Common mistakes and their solutions
Even with the right setup, the Xiaomi repeater can run unstable, and here are the typical problems and ways to fix them:
| Problem. | Possible cause | Decision |
|---|---|---|
| The repeater does not connect to the router | Incompatible Wi-Fi standards or incorrect password | Check the supported frequencies (2.4/5 GHz) and re-enter the password |
| The indicator flashes red. | A weak signal from the router or a connection error | Move the repeater closer to the router or restart both devices |
| Low speed of the Internet via repeater | Network overload or interference from other devices | Change the Wi-Fi channel in your router settings (for example, from a car to 6 or 11) |
| The repetitor creates a separate network instead of amplification. | Settings select Access Point mode instead of Repeater | Reset the repeater to factory settings and set it up again |
If the repeater connects, but the Internet speed through it is much lower than when connecting directly to the router, try:
- 📡 Change the Wi-Fi channel in router settings (for example, from car to fixed 1–11 for 2.4 GHz).
- 🔄 Switch the repeater to another range (if 5GHz is supported).
- 🛠️ Update the firmware of the repeater and router to the latest version.
It’s also worth checking if your Wi-Fi channel is overloaded by neighboring networks, and use applications like Wi-Fi Analyzer (Android) or NetSpot (iOS) to show which channels are less loaded.

Optimizing the work of the repeater: tips for a stable signal
To make Xiaomi’s repeater work as efficiently as possible, follow these guidelines:
- 📍 Location: Place the repeater 1-1.5 meters from the floor and away from metal objects, mirrors and thick walls. The ideal location is the middle between the router and the dead zone».
- 🔋 Power. Don't use extension cords or network filters -- plug the repeater directly into the socket.
- 🔄 Automatic update. Enable this function in the repeater settings (System section) → Software update) so that the device installs the latest patches.
- 📶 Dual-band networks: If your router supports 5GHz and your repeater does not (like Mi Wi-Fi Repeater 2), set the router to only work in the 2.4GHz band or buy a 5GHz repeater.
To check the signal quality after setting up, use the Speedtest app or Wi-Fi SweetSpots. Measure the speed near the router and in the range of the repeater. If the difference is greater than 30-40%, try relocating the repeater.
Also, pay attention to the load on the network, if you have a lot of devices connected to the repeater (smartphones, smart light bulbs, TVs), the speed can drop.
- Limit the number of connected gadgets.
- Turn off background updates and downloads on connected devices.
- Set up QoS (Quality of Service) on your router to prioritize traffic (e.g. for video or gaming).
💡
If you have a dual-band router, set the repeater to amplify only one band (e.g., 2.4GHz), and leave the second band (5GHz) for direct connections, which will reduce the load on the repeater and improve stability.
Resetting the repeater Xiaomi to factory settings
If the repeater is not working properly or you have forgotten the password from its network, you may need to reset.
- Find the Reset button on the repeater body (usually recessed and signed).
- Take a paperclip or toothpick and press the button, holding it for 5-10 seconds until the indicator starts to blink quickly.
- Release the button. The repeater will restart and return to factory settings.
After discharge:
- The name of the repeater network will become Xiaomi_XXXX or MiRepeater_XXXX.
- Password reset (by default access without password).
- All user settings (including network name and password) will be deleted.
If the repeater doesn’t want to connect to the application after reset, try:
- 🔄 Reboot the phone and repeater.
- 📱 Remove and reinstall the Mi Wi-Fi app.
- 🌐 Connect to the repeater network manually (via Wi-Fi settings on your phone).
⚠️ Note: On some models (e.g. Xiaomi AIoT Router) AX3600 In repeater mode, a factory reset can put the device back in router mode, and then you have to reconfigure it as a repeater.
