How to make a repeater from a Xiaomi router: the complete guide

Wireless network expansion is a major challenge for owners of large-sized apartments or private homes. Often, the signal from the main router does not reach far-flung rooms or the second floor, leading to constant connection breaks and low speeds. In such situations, the ideal solution is to use additional equipment, and Xiaomi routers have proven to be among the best here due to the flexibility of settings and affordable price.

Turning a second router into a repeater (or WDS access point) allows you to relay the signal of the main device, creating a single seamless network. This saves you money, since you don't need to buy specialized signal amplifiers if you already have a spare router. In this article, we'll detail how to configure the bundle between devices to work consistently and efficiently.

The setup process does not require a deep knowledge of network technology, but requires careful input. It is important to understand that not all router models support WDS or repeater mode out of the box, but most Xiaomi and Redmi brand devices have the necessary functionality in standard firmware. We will consider a universal algorithm of actions that will suit most popular models.

Preparation of equipment and selection of installation site

Before you start setting up, you need to find the right place to install the future repeater, and the ideal location is somewhere in the middle between the main router and the area where the signal is weak, and if you put the repeater too far from the signal source, it will retrand the already weak and noisy signal, which will not increase the speed.

You'll need the Xiaomi router itself, which will run in repeater mode, and a computer or smartphone for initial setup. LAN-cable, although modern models allow you to perform all the actions over Wi-Fi. Make sure you know the password from your main network, as it will be required to pair devices.

Also worth checking is the firmware version on both devices. Manufacturers often release updates that improve the stability of WDS bridges and fix security bugs. Go to the main router settings and check for updates in the Status → System Version section.

⚠️ Note: Before setting up, it is recommended to reset the Xiaomi router to factory settings, if it has been previously used. IP-address.

Setting up the main router to work in a bundle

For successful wireless bridge organization, the main router must have a static IP-address and fixed channel. If the channel changes automatically, the communication between the devices may break. Go to the control panel of the main router (usually 192.168.1.1 or 192.168.0.1) and find the wireless network settings.

In the Wireless Settings section, look at the Channel setting. Select a specific value, such as 1, 6 or 11 for the 2.4 GHz band, and record it. Write this number down, as it should be identical on the second router. Also check if the WDS or Bridge feature is enabled if it is explicitly present.

The important point is the setting DHCP-The main router has to turn it on, because it's the router that's going to give out. IP-The second router in the network will operate in a transparent bridge mode, and it will be connected to all connected devices in the network. DHCP-We will disable the server to avoid addressing conflicts.

💡

Use the 5GHz band to bridge the routers if both devices support this frequency, which will provide faster data rates and less interference.

After you make the changes, save the settings. If the main router asks for a reboot, do it. Now your main device is ready to accept the connection from the second node on the network.

Step-by-step instructions for setting up the Xiaomi router in repeater mode

Connect to Xiaomi’s router, which will become a repeater, either via Wi-Fi or cable. Open your browser and enter the control panel address (often 192.168.31.1 for Xiaomi or miwifi.com). If the router is new, it will offer quick setup — while skip it or select manual settings.

Find the settings section associated with the mode of operation. In the MiWiFi interface, this can be the Settings tab. → Select Repeater Mode or Wireless Bridge, if this option is not explicitly available, you must manually configure it. WDS.

When manually configuring WDS, follow the following steps:

• 📶 Go to Wi-Fi Settings and enable the function WDS (if available).
• 🔍 Click the Search or Scan button to find your main router’s network.
• 🔑 Choose. SSID Main network and enter the password from it.
• 🌐 Make sure the channel matches the main router channel.

After entering all the settings, press Save. The router will try to connect to the main network. The Wi-Fi indicator on the device body should stop flashing and light up with a flat light (usually blue or green), indicating a successful connection.

Conflicts IP-addresses and settings DHCP

One of the most common problems when creating a network of two routers is conflict. IP-By default, many Xiaomi routers have 192.168.31.1, and other brands have 192.168.0.1 or 192.168.1.1. If the addresses match, the network will not work.

To avoid this, change before connecting to the main router LAN IP-For example, if the main router has an address of 192.168.1.1, give the second one the address of 192.168.1.250. LAN → Settings DHCP-server.

Critical: DHCP must be disabled on a router replica, address distribution is handled only by the host device, and if you leave DHCP on both routers, your gadgets will get the gateway settings wrong and will not be able to access the Internet.

After the change IP-You'll need to re-enter the router's address, using the new address. Save the settings and reboot the device.

⚠️ Attention: After disconnection DHCP on the second router, access to its settings is possible only by a new static IP-address you gave him.

Organization of seamless roaming (Mesh-like network)

In order for devices to automatically switch between routers without breaking the connection, network names (SSID) and passwords must be identical. However, just the same name does not guarantee true 802.11r/k/v roaming, but it makes life much easier for users.

You can set the second router to the same network name and password as the main router, but the difference is that some experts recommend that you use different channel names to visually distinguish the devices in the list of available networks, but for the client it will be one network.

Modern Xiaomi routers with EasyMesh technology allow you to combine devices into a single system (one-click). If both of your devices support this feature, use the Mi Home app or web interface to add a new node to an existing network.

Check the network by walking around the house with your smartphone on, play a video stream or an online game, and if the video doesn't buffer when you go from room to room, and the ping in the games doesn't jump, then the setup has been successful.

Diagnosis of problems and typical errors

Even with the exact instructions, it can be difficult, and the most common problem is that the devices connect to the repeater, but the Internet doesn't work. DNS Make sure you're setting up the lock. WAN The repeater is in the “dynamic” mode IP» (Dynamic IP), Not PPPoE or Static. IP, unless the provider requires otherwise.

Another common mistake is choosing the wrong type of encryption: the main and auxiliary routers must use the same security protocol, for example, WPA2-PSK. If one runs on WPA3 and the other on WPA2, the bridge may not install.

If the speed through the repeater is significantly lower than directly from the main router, check the signal level at the repeater installation point. it should be at least -70 dBm. Also make sure you use a 20 MHz channel width for the 2.4 GHz band, as 40 MHz in noisy air gives more errors and packet losses.

⚠️ Warning: Do not place your router near microwave ovens, baby monitors or bluetooth speakers.These devices cause severe interference in the 2.4 GHz band.

💡

The stability of the repeater depends on the quality of the signal it receives from the main router, not on the power of its own antennas.
