Wi-Fi expansion is one of the most pressing challenges for owners of large apartments or multi-storey buildings. Often, the power of a single device, even one as advanced as the Xiaomi Router AX3600 or Mi Router 4A, is not enough to provide a stable signal in the back room, the solution is to use a second router, which can be turned into an access point or a repeater, creating a single seamless network.
Xiaomi ecosystem owners are in a good position to provide flexible network management tools through the Mi Home app and web interface. However, the customization process has its own nuances, depending on the firmware version and hardware model. Seamless roaming or simple signal relaying requires the right sequence of actions to avoid conflict. IP-addresses and breaks of connection.
In this guide, we will discuss all the available ways to combine two Xiaomi routers into a single infrastructure, learn about the differences between modes of operation, methods of cable and wireless connection, and how to configure automatic switching of devices between access points without losing speed.
Choosing the right router connection scheme
Before you start setting up, you need to decide on the topology of the future network, which is not only the stability of the connection, but also the maximum speed that your gadgets can develop. There are two main approaches: wired connection (Ethernet) and wireless bridge (Wi-Fi).
The ideal option is always to lay the cable between the main and secondary router, in which case the second router operates in the access point mode, providing maximum speed and minimal delays. If the cable is not possible, use the wireless bridge or repeater mode, which inevitably reduces the channel capacity.
It is important to consider that to create a full-fledged Mesh-network with seamless roaming (EasyMesh), it is desirable to use routers of the same line or model. Different Xiaomi models may not support automatic customer switching, working only as independent points with the same network name (SSID).
When choosing a wireless method, be aware of physical obstacles, walls and overlaps can critically reduce the signal quality between routers, making the second device inefficient, and in such cases, it is better to consider alternative options for network expansion.
Preparation of equipment and resetting of settings
The process should begin with the preparation of a secondary router, which will act as a network extension. If the device has been previously used, it is strongly recommended to perform a full reset to factory settings. DHCP-server.
To reset, find the Reset button on the case. It's usually recessed in the case, so you'll need to use a paper clip or a needle. Press and hold the button for a period of time. 5-10 It's a moment before the status indicator starts flashing orange. reset_ launched.
☑️ Preparation for network setup
After you restart, connect to the Wi-Fi network of the secondary router. Xiaomi_XXXX It doesn't require a password, or it's on a sticker at the bottom of the device, and you can now start directly configuring it through a web interface or a mobile app.
⚠️ Attention: Don't plug in WAN-port of the second router to the main until the setup is complete, unless you are using automatic Mesh mode. DHCP-servers and shut down the entire network.
Set up a Mesh system through the Mi Home app
The easiest and most modern way to combine Xiaomi routers is using Mesh technology, which allows you to create a single network with a single name and password, where switching between points occurs automatically, and models with the AX, AC2100 and later support this function.
To start, make sure the main router is already configured and has internet access. Open the Mi Home app on your smartphone, select your main router and go to settings. Find the section responsible for managing the network, often called the Mesh network or Add node.
Turn on the secondary router and bring it close to the main one (at a distance of 1-2 meters). In the application, click the button for finding new devices. The system automatically detects compatible hardware and suggests adding it to the Mesh system.
What if the routers can’t see each other?
Once you've successfully combined, you can spread routers around the apartment, the system optimizes the communication channels itself, and if you're using a wired connection between nodes, remember to switch the mode in the application settings to "Ethernet backhaul" for maximum performance.
Access Point Mode for a wired connection
If you have a cable between the routers, you'd better use the hotspot mode, and unlike the router mode, the second device just broadcasts the Wi-Fi signal, and the distribution is the same. IP-The main gateway handles the addresses. NAT.
Connect your computer to the secondary router and log in to its web interface at 192.168.31.1. Go to Settings → Operation Mode. Select Access Point or Wired Mode.
The system will alert you to restart. IP-The router's address will change, the main router will give it away. IP in the list of clients of the main router, in order to be able to manage the settings of the access point in the future.
| Parameter | Main router | Secondary (AP Mode) |
|---|---|---|
| IP-address | 192.168.31.1 (example) | Dynamic (from the main) |
| DHCP server | Included | Shutdown automatically |
| WANN POW | Connected to the provider | Unused (usually) |
| LAN ports | For clients. | For customers and communication with the main |
Now connect it. LAN-port WAN (or LAN, Depending on the model and firmware, the secondary device port is cabled, and the network should be activated instantly by giving the devices access to the Internet through a single subnet.
The organization of a wireless bridge (Repeater Mode)
When cable laying is not possible, Xiaomi's secondary router can be configured as a wireless repeater, in which mode it takes a signal from the main router over Wi-Fi and distributes it further, which is convenient, but the Internet speed on the second router's customers can drop to 50% of the real one.
In the secondary router's web interface, go to Wi-Fi settings or System status. Find Repeater or Wireless Bridge. The system will offer a list of available networks.
Select your main router's network and enter your password. Once you save the settings, the router will try to connect. A successful connection is usually indicated by the blue color of the indicator. If yellow or red is on, the signal is too weak, and the router needs to move closer to the source.
💡
To improve the stability of the wireless bridge, use the 5GHz band for communication between routers, if the model allows for stream sharing. This will free up the 2.4GHz band for your smartphones and IoT devices.
It is important to understand that in repeater mode, both routers must be on the same channel or be able to automatically select a channel. Static channel settings can lead to interference if the main router decides to change frequency due to air noise.
Set up a single SSID and seamless roaming
The key to building a single network is to properly configure network names (SSIDs) so that devices can perceive two routers as one network, the Wi-Fi names and passwords must be identical on both devices. The letter register matters.
But a simple name match doesn’t guarantee seamless roaming; a smartphone can cling to a weak signal from a long-distance router until the connection is completely lost. 802.11k/v/r These functions are activated automatically in Mesh mode.
If you are manually configuring the network (without Mesh), make sure the encryption types are the same (e.g. WPA2-PSK/AES on both devices).
💡
The ideal configuration for roaming is the same SSID, the same password, the same type of encryption, but different non-intersecting channels (1, 6, 11 for 2.4 GHz).
Check the network by walking around the apartment with a speed test or video call running. Switching should be almost imperceptible, with minimal ping. If there are delays, try to reduce the transmitter power on the main router so that customers switch to the nearest point earlier.
Typical Problems and Conflicts
During the setup process, users often encounter a problem where devices cannot get a hold of the device. IP-It's a classic sign of conflict. DHCP-Make sure that on the secondary router (in modes) AP or Repeater server DHCP disabled unless it is done automatically.
Another common mistake is using the same IP-If both have 192.168.31.1, there will be a conflict. LAN IP a secondary router to an address on the same subnet but with a different last octet, such as 192.168.31.2.
⚠️ Note: When updating the firmware of one of the routers in the Mesh network, the process can take up to 15 minutes. Do not turn off the power of the devices during this period, otherwise you can get a "brick" or desynchronization of software versions.
If you only have internet on one of the routers, check your settings. DNS. Sometimes providers block the operation of several devices at one time. NAT, If the bridge mode is not used, cloning is used. MAC-Main router addresses to secondary may help, but this is rare for home networks.
