A weak Wi-Fi signal in distant rooms or on multiple floors is a common problem faced by apartment and private home owners. Instead of buying an additional router or an expensive mesh system, you can use the existing Xiaomi router in repeater mode, which allows you to expand the coverage of the network without laying cables and significant financial costs.
However, not all Xiaomi models support the repeater mode out of the box, and the setting is nuanced depending on the firmware version and the type of main router. In this article, we will discuss which models are suitable, how to connect them correctly, what settings optimize the repeterβs operation and how to avoid typical errors that lead to loss of speed or unstable connection.
You'll know:
- π What Xiaomi routers can be used as a repeater (including outdated and new models).
- βοΈ Step-by-step instructions for setting up via the web interface and the Mi Wi-Fi app.
- πΆ How to choose the optimal location of the repeater for maximum coverage.

What Xiaomi routers support repeater mode
Not all Xiaomi devices can run in repeater mode. The main limitation is hardware support for the feature. WDS (Wireless Distribution System) or Repeater Mode. Below is a table of compatibility of popular models:
| Model router | Support for the repetitive regime | Firmware | Notes |
|---|---|---|---|
| Xiaomi Mi Router 4A (Gigabit Edition) | β Yes. | Official/Castomic | Manual adjustment required WDS |
| Xiaomi Mi Router 4C | β Yes. | Official (version 2.0)+) | "Network amplifier" mode in the web interface |
| Xiaomi Mi Router 3/3G/3C | β οΈ Partially. | Castomium (Padavan, OpenWRT) | There is no official firmware in the |
| Xiaomi AX3600 / AX6000 | β Yes. | Official. | Support for Mesh Networks (it is better to use this mode) |
| Xiaomi Mi Router 4Q | β No. | Anybody. | Customer mode only (without relay) |
Important: If your model does not support the repeter mode on the official firmware, you can install an alternative (for example, Padavan). However, this requires experience and may not be warranty. For beginners, we recommend choosing a model with native support (for example, Mi Router). 4C or AX3600).
β οΈ Note: Xiaomi routers with firmware for the Chinese market (for example, with suffix) CN) may not have a Russian-language interface or limit functionality.
Preparation for setting up: what to do before turning on the repeater mode
Before you switch the router to repeater mode, follow a few mandatory steps:
- Update the firmware of the main and auxiliary routers. Outdated versions of the software may contain errors that interfere with the stable operation of the repeater.
- Write down the main network settings: name (SSID), password, type of encryption (WPA2-PSK or WPA3), channel (20/40/80 MHz).
- Place the router in the zone of the main networkβs confident signal (at least 70% of the signal level).
- Disconnect all devices from the future repeater (by cable and Wi-Fi), except the computer for setup.
If the main router uses 5 GHz and the repeater only supports 2.4 GHz (e.g. Mi Router) 4C), You'll have to configure the relay only for the 2.4 GHz band, which will lower the top speed, but will ensure compatibility.
Update the firmware of both routers|
Write it down. SSID, password and channel of the main network|
Place the repeater in the good signal zone (70%+)|
Disconnect all devices from the repeater except the PC for settings|
Check the compatibility of the ranges (2.4/5 GHz)

Critical error: If the main router uses a dynamic channel change (Auto Channel feature), the repeater may lose the connection.
Step-by-step setting up the Xiaomi router in repeater mode
Consider two ways of setting up: through the web interface (universal method) and through the Mi Wi-Fi application (easy for beginners).
Method 1: Configure via web interface
1. Connect the router-repiter to the computer via cable (LAN-port or via Wi-Fi (if it already distributes the network).
2. Open your browser and type in the address bar 192.168.31.1 (or miwifi.com). log in (the default login and password is usually admin).
3. Go to the Additional Settings section β Work mode (or Working Mode in English) Select Repeater Mode (network amplifier).
4. In the list of available networks, select your primary SSID, Enter your password and save your settings.
5. Wait for the reboot (1-2 After that, the router will relay the network with the same name, but with a suffix _EXT or _REPEATER.
What if there is no repeater mode in the web interface?
Method 2: Configure via the Mi Wi-Fi app
1. Install the Mi Wi-Fi app (available for Android and iOS) and connect to the router-repider network.
2.In the main menu, select your router and go to Settings β Mode of work.
3. tap the option Network Amplifier (Repeater) and select the main network from the list.
4. Enter the password and confirm the changes. The router will reboot.
Note: Mi Wi-Fi may not have a repeater option for some models (e.g. Mi Router 3).
1. Whether ranges match (2.4/5 GHz) main router and repeater.
2. whether the main router is disabled filter on MAC-address.
3. Is the password entered correctly (the registry matters!).-->
Optimizing the work of the repeater: how to avoid loss of speed
The main problem with using a repeater is the speed reduction due to double data relay. To minimize losses, follow these recommendations:
- π‘ Place the repeater at an optimal distance: too close to the main router - useless, too far - the signal will be weak: 50-70% signal level from the main source.
- π Use different channels for the main router and repeater: if both are running on the same channel, interference occurs.
- π Disable unnecessary functions: Deactivate QoS in the repeater settings, IPv6 (if not used and the Guest Network - they consume resources.
- π Connect the repeater over cable (if possible): some models (e.g, AX3600) Support Mesh mode via Ethernet, which eliminates speed losses.
Speed test: After setting up, check the speed of the repeater connection and compare it to the direct connection to the main router. If the drop is greater than 30%, try:
- Change your Wi-Fi channel to a less loaded one (use applications like Wi-Fi Analyzer).
- Switch the repeater to a different range (from 2.4 GHz to 5 GHz if supported).
- Reduce the channel width from 40 MHz to 20 MHz for stability.
β οΈ Note: If the main router is using WPA3, And the repeater only supports WPA2, You will need to temporarily switch the main network to WPA2-PSK Or use another repeater. WPA2/WPA3 may work unstablely.
Typical errors and their solutions
Even when you set it up properly, users face problems, and here are the most common ones and how to fix them:
| Problem. | Possible cause | Decision |
|---|---|---|
| The repeater is not connected to the main network. | Incorrect password or incompatible type of encryption | Check the password, switch the main router to WPA2-PSK |
| The network of repeaters appears, but the Internet is not available | Unplugged. DHCP repetitive IP-address | Enable DHCP or assign static IP manually |
| Frequent connection breaks | Weak signal or interference from other networks | Move the repeater closer to the router or change the channel |
| Low speed (less than 10 Mbps) | The repeater operates in the 2.4 GHz band on the loaded channel. | Switch to 5 GHz or reduce the channel width |
If the Xiaomi repeater periodically βhangsβ and requires a reboot, check:
- π₯ Overheating: routers without active cooling (e.g. Mi Router) 4A) They can brake for long periods of time. Place the device in a ventilated place.
- β‘ Unstable power: use the original power supply. Cheap analogues can cause failures.
- π± Too many connected devices: The repeater is not designed to work with 20 devices at the same time+ Limit the number of gadgets.
π‘
If the Xiaomi repeater doesnβt save the settings after the reboot, reset it to the factory (Reset) and repeat the setting. This is a common problem when using custom firmware.
Alternatives to Repeter Mode: When to Use Mesh or Client Mode
Repetitor mode is not always the best solution, and in some cases it is better to consider alternatives:
- π Mesh Network: If you have a Xiaomi router AX3600 or AX6000, Set Mesh instead of repeater, and that'll allow smooth roaming between nodes without breaks.
- π Client regime (WISP): Suitable if only wired devices need to be connected to the repeater (for example, Smart). TV). It works as a Wi-Fi adapter for the LAN-port.
- πΆ Powerline adapters: If cable laying is not possible and the Wi-Fi signal is weak, use Powerline adapters (wiring data transmission).
Comparison of repeater and Mesh:
| Parameter | Repeat regime | Mesh-network |
|---|---|---|
| Speed. | Fall to 50% | Fall to 20-30% |
| roaming | No (manual reconnect) | Yeah (automatic) |
| Difficulty setting up | Low. | Medium |
| Compatibility | Any routers. | Supported models only |
If your main router is not Xiaomi, but, for example, TP-Link or ASUS, The repeater regime may work unstable due to differences in implementation WDS. In this case, it is better to use a universal repeater (for example, Xiaomi Mi Wi-Fi Range Extender) or configure the client mode with the switched off. DHCP.
Security: How to Protect Your Network When Using a Repetitive
The repeater expands the coverage, but also increases network vulnerabilities.
- π Turn it off. WPS: This feature is vulnerable to brute force attacks. WPS and deactivate it.
- π‘οΈ Use a complex password: For a repeater network, set a password at least 12 characters long with numbers and special characters.
- π Hide. SSID: In the repeater settings, enable the option to Hide the network (Hide). SSID), Not to be displayed on public lists.
- π± Restrict access to MAC: In Access Control, whitelist only your devices.
If the repeater is used in a public place (such as a cafe or office), set up a guest network with a speed limit and Internet access only (without a local network) to prevent unauthorized access to other connected devices.
β οΈ Note: Some Xiaomi models (e.g. Mi Router) 4A) They have a vulnerability in the web interface that allows you to remotely reset your settings. Update your firmware and disable access to the control panel from the external network (Remote management).
