How to set up two Xiaomi routers on a single Wi-Fi network: 3 working methods

Combining two routers Xiaomi into a single wireless network is a challenge faced by owners of large apartments, private homes, or offices where the coverage of a single device is insufficient. The main goal of such a setup is to ensure seamless roaming (automatic switching between access points without interrupting the connection) and expand the range of a stable signal. However, many users make mistakes: they incorrectly select the second router's operating mode, fail to sync security settings, or encounter "double NAT," which leads to problems with online gaming and IP cameras.

In this article we will look at three proven methods router aggregation Xiaomi (including models Mi Router 3/4/4A/4C/AX3600) via Wi-Fi: via WDS bridge, mode repeater and setting client bridgeEach method has its own nuances: some require manual channel configuration, while others require MAC address binding. We will also provide unique solutions for typical mistakes, such as no internet on the second router or a "split" network (when devices see two separate Wi-Fi networks instead of one).

1. Preparing for setup: what to check before combining routers

Before you begin setting up, make sure your routers are Xiaomi meet key requirements:

• 🔄 Both devices must support one of the unification modes: WDS, Repeater or Client Bridge. Check this in the model specifications (e.g. Mi Router 4A does not support WDS, but works in repeater mode).
• 📶 Routers must use the same Wi-Fi standard (For example, 802.11ac or 802.11ax). If the main router is running on 5 GHz, and the secondary one is only on 2.4 GHz, the connection speed will drop by 2-3 times.
• 🔒 Passwords and encryption methods (WPA2-PSK or WPA3) on both devices must match. Otherwise, the devices will not be able to establish a connection.
• 📡 It is desirable that the routers are located in the zone stable signal each other (at least 70% reception level). Check this through the app Wi-Fi Analyzer on a smartphone.

Pay special attention Wi-Fi channelsIf the main router operates on automatic channel selection, fix it manually (for example, on Channel 6 For 2.4 GHz or Channel 36 For 5 GHz). This will prevent connection interruptions when changing channels. You can check the current channel in the router's web interface by following this path: Settings → Wi-Fi → Additional settings.

⚠️ Attention: If you use routers of different generations (for example, Mi Router 3 And AX3600), disable support on the old model 802.11b in the Wi-Fi settings. This outdated standard reduces the entire network speed to 11 Mbps.

2. Method 1: WDS Bridge (recommended for models with support)

WDS (Wireless Distribution System) — the most reliable way to connect routers Xiaomi into one network if both devices support this protocol. Unlike repeater mode, WDS allows you to connect wired devices (via LAN ports) to the secondary router and preserves the original network name (SSID).

Instructions for the main router (for example, Mi Router 4):

1. Connect to the web interface at 192.168.31.1 (The default login and password are usually a combination admin/admin).
2. Go to Settings → Wi-Fi → Additional settings and turn on the option Enable WDS.
3. In the field MAC address of the remote bridge Enter the MAC address secondary router (indicated on the sticker on the case).
4. Save the settings and reboot your device.

Instructions for a secondary router (for example, AX3600):

1. In the web interface of the secondary router, go to Operating mode → Bridge (WDS).
2. Select the main router network from the list of available ones and enter its password.
3. In the section LAN settings turn it off DHCP server (to avoid IP address conflicts).
4. Set the secondary router's IP address manually (e.g. 192.168.31.2, if the main one has 192.168.31.1).

After setup, test the connection: connect to Wi-Fi from your phone and move between routers. If the network is "split" (the phone sees two identical networks), update the firmware on both devices via Settings → Software Update.

3. Method 2: Repeater mode - simple, but with limitations

If your routers Xiaomi do not support WDS (for example, Mi Router 4A), use the mode repeaterThis method is easier to set up, but has two key drawbacks:

• 📉 Internet speed on the secondary router is decreasing 2 times (since data is transmitted back and forth over one channel).
• 🔌 To the LAN ports of the secondary router You cannot connect wired devices - they will not have access to the network.

Step-by-step instructions:

1. Reset the secondary router to factory settings (press and hold the button Reset for 10 seconds).
2. Connect to its Wi-Fi network (type name Xiaomi_XXXX) and open the web interface at 192.168.31.1.
3. Go to Operating mode → Repeater.
4. Select the main router network from the list and enter its password.
5. Wait for the reboot. Done—the secondary router is now relaying the primary router's signal.

⚠️ Attention: In repeater mode Xiaomi Routers sometimes "lose" settings after a firmware update. Before upgrading the firmware, back up your configuration using Settings → Backup.

To improve the connection stability in the mode Repeater, perform additional steps:

• 🔄 In the settings of the main router, fix Wi-Fi channel (do not leave it on "Auto").
• 📶 Install a secondary router at a distance 5–10 meters from the main one - this is the optimal distance for the balance of signal and speed.
• 🔒 Disable the function on the main router Smart Connect (if any) to avoid automatic switching between frequencies 2.4 GHz And 5 GHz.

4. Method 3: Client Bridge - for wired devices

Mode client bridge Suitable if you need to connect to a secondary router Xiaomi Wired devices (such as a Smart TV, game console, or IP camera) can be connected while still connecting the networks via Wi-Fi. Unlike WDS, the secondary router doesn't rebroadcast Wi-Fi, but only forwards the internet to its LAN ports.

Configuration algorithm:

1. On the main router, turn on WDS (as in Method 1) and add the MAC address of the secondary device.
2. On the secondary router, go to Operating Mode → Client Bridge.
3. Select the main router network and enter the password.
4. Turn it off DHCP server and assign a static IP to the secondary router (for example, 192.168.31.3).
5. Connect wired devices to the LAN ports of the secondary router.

The advantage of this method is minimal speed loss (unlike repeater mode), since traffic is not relayed over the air. However, there is a drawback: devices connected to the secondary router will be in separate subnet, which can create problems for local gaming or file streaming.

5. Common mistakes and their solutions

Even when following the instructions precisely, users often encounter problems. Let's look at the most common ones:

If after setting up the device (smartphones, laptops) two identical networks are connected but do not switch between them automatically, the problem lies in the settings roamingManually install on both routers:

• 🔹 Same SSID (network name).
• 🔹 Same password and encryption type (WPA2-PSK or WPA3).
• 🔹 Same channel (eg. Channel 1 For 2.4 GHz).
• 🔹 Disable the feature Smart Connect (if any).

⚠️ Attention: If you are using routers with firmware Padavan or other custom builds, WDS settings may differ. In this case, check the documentation for your specific firmware version.

6. Optimizing the Unified Network: How to Improve Speed ​​and Stability

After successfully combining the routers Xiaomi on the same network, make additional settings to maximize performance:

• 📶 Frequency separation: Set up 2.4 GHz And 5 GHz on different channels. For example:
  • 2.4 GHz: channel 6, width 20 MHz.
  • 5 GHz: channel 36, width 80 MHz.
• 🔄 Firmware update: Check that the software on both routers is up to date. For Xiaomi Updates are released every 2-3 months and often fix WDS bugs.
• 🛡️ Security: Turn it off WPS and turn it on WPA3 (if supported). This will protect the network from connecting to unauthorized devices.
• 📊 Traffic prioritization: In the settings QoS (Quality of Service) Prioritize video and voice if you use IP telephony or streaming.

To check the speed and stability of the connection, use the following utilities:

• Wi-Fi Analyzer (Android) - to analyze channel load.
• Speedtest.net — to measure speed on different devices.
• PingPlotter — to diagnose delays and packet losses.

If the speed on the secondary router is lower than expected, try:

1. Reduce the distance between routers.
2. Switch from 2.4 GHz on 5 GHz (if both routers support it).
3. Disable the function on the main router Band Steering (if it interferes with manual frequency selection).

7. Alternative options: when Wi-Fi merging isn't suitable

If none of the described methods provide a stable connection, consider alternatives:

• 🔌 Wired LAN-to-LANConnect the routers with a cable EthernetThis is the most reliable method, but requires cable installation.
• 📡 Mesh systems: Replace routers with Xiaomi Mesh (For example, AX3000T or AX6000T), which support automatic roaming.
• 🔗 Powerline adapters: Use adapters TP-Link AV1000 or similar devices for transmitting internet via electrical wiring.

Wired association (LAN-to-LAN) is configured as follows:

1. Connect the ports LAN the main and secondary routers with a cable.
2. On the secondary router, disable DHCP and assign an IP from the main subnet (for example, 192.168.31.2).
3. Set the same SSID and passwords on both devices.

The advantage of this method is maximum speed (up to 1 Gbps) and no signal loss. The downside is the need for cable installation.
