Combining two Xiaomi routers into one Wi-Fi network: all the ways and nuances

Why combine two Xiaomi routers and what it does

Connecting two Xiaomi routers into a single network is a challenge faced by owners of large apartments, private homes or offices, where the coverage of one device is not enough. AX6000 or Redmi Router AX5 They may not reach the signal to remote rooms, especially if concrete walls or metal structures are encountered in the way.

The main advantages of this scheme:

• 📶 Expanding coverage without losing speed (when set up correctly)
• 🔄 Seamless roaming (if supported): Devices automatically switch between routers without breaking the connection
• 💻 A single network for all connected gadgets: printers, smart lamps and cameras Xiaomi will be available from any device
• 🔌 Channel backup: You can split the load (for example, one router for 2.4 GHz, another for 5 GHz)

However, it is not so simple: the wrong combination can lead to a drop in speed, conflicts. IP In this article, we will discuss all the working ways of connecting two Xiaomi routers over Wi-Fi, from standard repeater mode to advanced mode. WDS-The bridge, and also tell you which models support certain functions.

How to combine Xiaomi routers: which to choose

There are three main methods of connecting two Xiaomi routers wirelessly, each with its own pros, cons and limitations across models:

Which way to choose?

• 🏠 For a small apartment (up to 100 m2), the repeater mode is suitable - it is easy to set up even for a beginner.
• 🏡 For a house or a large apartment (100-200 m2) optimal WDS-Bridge – it provides a single network with minimal losses.
• 🏢 For an office or multi-storey house with multiple routers, a Mesh network is better, but only if all devices support AiMesh.

⚠️ Note: If you have routers of different brands (such as Xiaomi and TP-Link), mode WDS-The bridge may not work smoothly, in which case use repeater mode or connect the second router via cable.

Preparing Xiaomi routers for unification: 5 mandatory steps

Before setting up the connection, follow these steps to avoid errors:

Update the firmware on both devices to the latest version

Reset the settings to factory (reset button for 10 seconds)

Write it down. MAC-addresses of both routers (on the sticker or in Settings) → Status)

Select the main router (the one that is connected to the Internet)

Turn off on a secondary router DHCP-server (if used) WDS Mesh)

-->

Pay special attention to firmware. Outdated versions (e.g. MiWiFi) ROM 1.0 on the Mi Router 3G) may not support WDS Update the software via the web interface (Settings) → Update firmware) or official Mi Wi-Fi app.

Also check which Wi-Fi channel is used on the main router.

• 📡 At 2.4 GHz, select channels 1, 6, or 11 (they don't overlap).
• 🚀 Nana 5 GHz, use channels 36-48 or 149-165 (they're less loaded).

💡

If you have a Redmi Router AX5 Or, later, enable Smart Connect in your Wi-Fi settings. It automatically distributes devices between the 2.4 and 5 GHz bands for maximum speeds.

Method 1: Repeater mode is simple, but not perfect

This method is suitable for any Xiaomi model, including the outdated Mi Router 3 or Mini.The bottom line is that the second router connects to the first as a client and relays its signal, creating a second network (usually with a suffix _EXT).

Step-by-step:

1. Connect the second router to your computer via cable or Wi-Fi (to its own network).
2. Go to the web interface at the address 192.168.31.1 (default login/password — admin/admin or see sticker).
3. Go to Settings. → Mode and select Repeater (Amplifier).
4. In the list of available networks, select SSID your main router and enter your password.
5. Save the settings and restart the device.

After setting up the second router will create a new network with the type name. Xiaomi_EXT. You can connect to it in the same way as the main one, but the speed will be lower due to double relay.

⚠️ Note: In repeater mode, you cannot use the same SSID For both routers, this will lead to conflicts and connection breaks. If you want a common network name, use it. WDS-bridge.

Method 2: WDS-Bridge – a single network without loss of speed

WDS (Wireless Distribution System is a technology that allows you to combine two routers into one network with a common network. SSID Unlike repeater mode, there's no double relay, so the speed loss is minimal (5-15%).

However, not all Xiaomi routers support WDS. Here is a list of compatible models:

• ✅ Mi Router 3, 3G, 3C, 4, 4A, 4C
• ✅ Redmi Router AC2100, AX5, AX6
• ❌ Mi Router Mini, Mi Router HD (no support WDS)

Setting up WDS-The bridge consists of two stages: configuration of the main and secondary routers.

Step 1: Set up the main router

1. Go to the main router's web interface (192.168.31.1).
2. Go to Settings → Wi-Fi → Additional settings.
3. Turn on the option Enable WDS.
4. In the field MAC-Enter the address of the remote bridge MAC-address of secondary router (indicated on the sticker).
5. Save the settings and restart the device.

Step 2: Set up a secondary router

1. Connect to the second router and go to its settings.
2. In the Settings section → Wi-Fi installations are the same SSID and the password that's on the main router.
3. Go to Settings. → Network → Local area network and shut down DHCP-server.
4. Turn it on. WDS enter MAC-main-router.
5. Set up static. IP-address for a secondary router (e.g. 192.168.31.2) to avoid conflicts.
6. Save the settings and restart both devices.

After the reboot, both routers must merge into a single network. Check the connection by connecting to Wi-Fi from different devices.

💡

The main difference WDS The Repeater is a single network (one of the two). SSID) However, both routers must maintain stable operation. WDS and use the same security settings (e.g, WPA2-PSK).

Method 3: Mesh Network (AiMesh) – Advanced Solution for New Models

Mesh technology (or AiMesh in Xiaomi routers) allows you to create a seamless network of multiple devices, where connected gadgets automatically switch between nodes without breaking the connection, ideal for large homes or offices where stability is important.

However, Mesh supports only new models:

• ✅ Mi Router AX9000, AX6000, AX3600
• ✅ Redmi Router AX6 (firmware 2.0.15+)
• ❌ Mi Router 4A, Redmi AC2100 older (no support)

Mesh network settings in Xiaomi routers are performed via the Mi Wi-Fi mobile application:

1. Install the application and connect to the main router.
2. Go to the Devices section → Add a Mesh node.
3. Follow the instructions on the screen: the application will find the second router and offer to combine them.
4. Wait for the synchronization (may take time) 2-5 minute).

Once set up, both routers will appear as a single network in the app, and Mesh’s main advantage is that it automatically selects the best channel and seamlessly switches between nodes.

⚠️ Note: If after setting up Mesh, some devices (such as Yeelight smart lamps) stop working, check the client isolation settings in the router's web interface.

Common mistakes and their solutions

When combining two Xiaomi routers, users often face typical problems, and here are the most common ones and ways to fix them:

If none of these methods worked, try an alternative firmware (like OpenWRT or Padavan). WDS Mesh, but requires experience with routers.
