How to set up a Xiaomi router in repeater mode: the full guide

The situation where in one part of the apartment Wi-Fi catches perfectly, and in the other signal disappears altogether or the speed drops to unacceptable values, familiar to many owners of smart equipment. This problem is especially acute in homes with thick walls or large area, where one access point Xiaomi is physically not enough to cover all the rooms. The solution is often to buy expensive equipment, but you may already have everything you need to improve the situation.

Using Xiaomi’s second router as a repeater allows you to expand your wireless network coverage without having to lay additional cables, which turns an old or additional router into a powerful signal amplifier that relays data from the main router to remote areas of the room, and the setup process is simple enough if you know where to look for the right parameters and what nuances to consider when pairing devices.

In this article, we will take a closer look at how to turn your gadget into an effective network expansion tool, which models support this feature out of the box, and what to do if standard methods do not work, learn how to eliminate connection gaps and ensure a stable Internet in every corner of your home using only the software capabilities of the ecosystem.

The principle of operation and the advantages of the repeater regime

The repeater mode allows the device to receive a signal from the main router and transmit it further, increasing the range of the network. Unlike simple expansion of the zone, Xiaomi Router in this mode creates a single logical network, which makes it easier to switch devices between access points, this is especially true for a smart home, where gadgets must always remain online.

The main advantage of using a bundle of Xiaomi routers is the ability to create a Mesh network or a simple WDS bridge, depending on the model and firmware. The user gets a single entry point, and the devices automatically connect to the source with the best signal. This eliminates the need to manually reconnect to different Wi-Fi networks when moving around the apartment.

⚠️ Note: With repeater mode, the real speed of the Internet can drop to 50% of the original, since the radio channel is used for both receiving and transmitting data simultaneously.

In addition, using a second router allows you to offload the main router, taking over a part of the customers, for example, IoT devices or guest gadgets. This increases the overall stability of the network and reduces latency, which is critical for online games and video calls.

  • 📡 Significant expansion of Wi-Fi coverage without cable laying.
  • 🔄 Automatic switching of customers between access points (roaming).
  • 🛡️ The ability to create a separate guest network on the second device.
  • ⚡ Reducing the load on the main router by distributing customers.

Compatibility check and equipment preparation

Before you start setting up, you need to make sure that your hardware supports the necessary functions. Not all Xiaomi routers models have built-in support for repeater mode or Mesh systems in standard firmware. Most often, this is the possibility in the Mi Router 4A, 4C, AX3600 and later, as well as in devices running MiWiFi.

You'll need the router itself, which will work as a repeater, and access to the main router that distributes the Internet. It's desirable that both devices are from the same manufacturer to ensure maximum compatibility of encryption and management protocols. If the main router is of another brand, configuration is possible through universal WDS mode, but functionality may be limited.

It is also important to know the main network settings (SSID) and password beforehand. Without this information, automatic configuration is impossible. It is recommended to reset the repeater settings to factory settings to eliminate configuration conflicts from previous use.

☑️ Check before setting up

Done: 0 / 4

Check the firmware version on both devices. The manufacturer often releases updates that improve bridge or repeater stability. Software updates are the first step to successfully integrating devices into a single system.

Configure via the router's web interface

The classic and most reliable way to turn a Xiaomi router into a repeater is to use a web-based interface. First, connect your computer or smartphone to the Wi-Fi network of the router you're configurating, or connect them with a cable. Open your browser and enter the address 192.168.31.1 or miwifi.com in the address bar.

Once you log in (the default password is often on the bottom sticker), go to the settings section. The interface may vary depending on the firmware version (Chinese or global), but the logic remains similar. You need to find the section related to the mode of operation or Internet connection.

From the settings menu, select Operation Mode or Internet Settings, and you will be asked to choose the type of connection you have, and look for Repeater, Bridge or Wi-Fi Repeater, and the router will then offer a list of available networks.

What to do if there is no “relayer” button?
If there is no explicit mode switch in the menu, try to find the Apps section» -> «The center plugin and install a plugin to expand the network. In some Chinese firmware, this feature is hidden and activated only after changing the region to China. Select your main Wi-Fi network from the list and enter a password. The router will try to connect to it. If everything goes well, the indicator on the case will change color (usually blue or green), and the interface will appear the status “Connected». 🌐 Log in to the web interface at 192.168.31.1. 🔧 Go to the "Settings" section» → «Mode of work». 📡 Select the main router network from the list of available. 🔑 Enter your password and save your settings. Using the Mi WiFi app to manage For smartphone users, the most convenient way to manage the ecosystem is the Mi WiFi app (or Xiaomi Home). This method allows you to set up a repeater in a couple of taps if the main router is also a Xiaomi product. The application will automatically detect a new device and prompt you to add it to the existing network. Run the application and make sure that your phone is connected to the main router. Press the button to add a new device (usually "+" in the corner). The application will find the router and offer to synchronize the settings. This means that the network name and password will be copied from the main device automatically. During the setup, the application may suggest choosing the "Mesh" or "Relayer" mode. ⚠️ Note: When synced through the app, all settings of the old router (if it was used before) will be completely deleted. Make sure you have backups of important settings if they are not stored in the cloud. Once the procedure is complete, the app will display the network topology, where you can see that the new router is connected as a child node, and from there you can control the priority of devices, adjust parental controls, and see the connection speed between nodes. If you have the ability, the best solution is to organize a full Mesh network. Unlike a simple repeater, Xiaomi Mesh system uses special algorithms to choose the optimal data path. This allows devices to move around the house without breaking the connection, which is critical for VoIP calls and video conferencing. To create a Mesh network, all nodes must be compatible and preferably of the same model or series. The setup is done through an application where you select the option "Add Mesh Node." The system will determine the best communication channel and adjust the frequencies to minimize interference. An important aspect of the Mesh is the ability to wired backhaul. If you can stretch the cable from the main router to the repeater, do this. In wired bridge mode, the speed will not be cut in half, and you will get maximum performance throughout the coverage area. Simple repeater (Wi-Fi) Mesh system (Wi-Fi) Mesh system (Cable) Loss rate Up to 50% Optimized (beamforming technology) Lossless (100% speed) Roaming Depends on client Seamless (802.11r/k/v) Seamless (802.11r/k/v) Control Separately or through the web Unified through the application Stability Average High When building a Mesh network, try to place nodes at a distance of no more than 10-15 meters. The solution to the network is a low signal from the network, if the network is not a successful one from the network, the network will not use the network. First, check if the repeater is too far from the main router, and it needs to be in the zone of reliable reception of the main signal in order to accurately relay it further. IP-Make sure the repeater is on mode. DHCP-client DHCP disabled) so that only the main router can give out addresses, if both devices try to give out addresses IP, lay-in». 💡It's critical that the Wi-Fi channels on both routers don't overlap or be set to Auto mode so that the devices don't jam each other. WPA3, And the repeater only supports WPA2, They may not connect, and in such cases, you have to temporarily reduce the security of the main network or update the firmware of the repeater. Use the built-in tools in the Mi WiFi app to diagnose, and there's an optimization check that tells you where to place your router. Don't ignore these tips, because the physics of radio waves dictates its rules, regardless of the power of the transmitter. Can you use a Xiaomi router as a repeater for another brand's router? Yes, it's possible through mode. WDS (Wireless Distribution System, if the main router also supports this technology, however, the setup will be more difficult: you will have to manually prescribe the router. MAC-And the stability of the link is lower than that of a single brand, does the Internet speed decrease when you connect through a repeater? And when you connect wirelessly, the speed almost always decreases, often by a small amount of time. 30-50%, since the radio module operates in half-duplex mode (receives and transmits in turn). Using a wired connection (Access Point Mode) or three-band routers helps avoid this fall. How do you reset if the repeater stops responding? Find a Reset hole on the router's body. Press it with a clip and hold it. 5-10 It's a second before the indicator flashes yellow or orange, and then it goes back to factory settings. Do all Xiaomi models support Mesh? No, Mesh support (EasyMesh or Xiaomi's proprietary protocol) is mostly based on models released after the launch. 2019 year (series) AX, AC2100 Older models can only operate in simple repeater or bridge mode.
