In a modern apartment or multi-storey building, there are often situations when the main router signal is not enough to comfortably use the Internet in all rooms, walls, floors and appliances create natural obstacles, which in the far corners of housing, the connection speed drops and video communication is interrupted, and in these cases, owners of Xiaomi routers wonder whether their equipment can be used as a signal amplifier.
Fortunately, Xiaomi’s ecosystem offers flexible options for creating a distributed home network. Most of the brand’s current routers, from low-end versions of the 4A series to top-end flagships with Wi-Fi 6 support, are able to operate in repeater mode, which allows you to not buy expensive additional equipment, but use an existing gadget that was idle or replaced with a newer one.
Using the second Xiaomi router in conjunction with the main one allows not only to expand the coverage area, but also to create a single seamless network if Mesh technology is supported. However, even without Mesh functions, competent setting of the second device as an access point or a repeater can dramatically improve the quality of communication in dead zones. In this article, we will discuss in detail the algorithms of actions for various connection scenarios.
Opportunities of Xiaomi routers in relay mode
Before you start setting up, it’s important to understand that not all models work the same way. Older firmware versions or budget devices may have limitations in functionality. However, most current models, such as the Mi Router 4A Gigabit Edition, Mi Router AX3600 and Xiaomi Router AX1800, have built-in software that allows you to manage your modes flexibly. A key feature is the support of Easy Mesh technology, which allows you to combine several routers into a single system with a common network name.
If your main router is not a Xiaomi product, the second router can still be used as a repeater, but the functionality may be limited, in which case the device will simply transmit the signal further, creating a subnet or cloning the SSID of the main router. It is important to consider that when using two different brands, automatic customer switching (roaming) may not work correctly, and the devices will “clung” to the weak signal of the main router instead of switching to a more powerful repeater signal.
Note that Repetitor Mode (WDS) and Access Point Mode (AP) are technically different things, although they are often confused in everyday life. AP mode requires cable laying from the main router to the second, which guarantees maximum speed, but not always convenient physically. The wireless repeater mode allows data to be transmitted over the air, which is convenient, but can reduce the final channel throughput by half, especially at 2.4 GHz.
Preparation for equipment setup
Before you start to change the configuration, you need to perform a number of preparatory steps, which will help to avoid conflicts. IP-Addresses and problems with access to the control panel. First, reset the settings of the second router (which will be a repeater) to the factory. 10-15 seconds until the indicators flash.
☑️ Preparation of equipment
Next, you will need to know the exact IP-main router address and range DHCP-This is usually the address of the type 192.168.1.1 or 192.168.31.1 for Xiaomi devices. AP), Make sure you have a free one. LAN-port on the main device and the length of the cable is sufficient for laying to the place of installation of the repeater.
⚠️ Warning: Before setting up, disable the provider's internet cable (WAN) from the second router, if it was connected, the setting is made only by connecting the computer or smartphone to the Wi-Fi network of the configurable device or through the LAN-cable.
It is also recommended to update the firmware on both devices to the latest version, which will ensure stability and the availability of all the current security protocols. Updates can be checked through the Mi Home application or the web interface at 192.168.31.1 (or current for your model).
Configure the Wi-Fi relay mode via the web interface
The most reliable way to turn a Xiaomi router into a repeater is to use a web interface. Connect to the network of the second router and enter it. IP-After logging in (the default password is often on the bottom sticker if you reset), go to the settings section. You need to find the mode item. Depending on the firmware version, it can be called “Working Mode”, “Working Mode” or be in the “System Settings” menu".
In the menu that opens, select the Wi-Fi Repeater option. The system will offer to scan the available networks. Select your main home network from the list and enter the password from it. Once you save the settings, the router will restart and try to connect to the main Internet source.
What if the repetitive regime is not found?
Once the connection is successful, the indicators on the repeater housing must change their behavior to signal that they are in client mode, so you can move the device to an area where the signal is weak, but still catches from the main router, and distribute it further.
Using Mesh Technology for Seamless Roaming
If you have two Xiaomi routers that support Mesh technology (like the AX series), the best solution is to create a single Mesh network, which will allow devices to automatically switch between access points without breaking the connection when you move around the house.
Turn on the second router next to the first (no more than a distance away) 2-3 Go to the Mi Home app, select the main router, and find the option to add a new device or expand the Mesh network. The system will automatically detect the second router and prompt to add it to the network. SSID And the password will pass automatically.
| Parameter | A regular repeater. | Mesh system | Access Point (AP) |
|---|---|---|---|
| Network name (SSID) | Maybe different. | Same (uniform) | Same (manually configured) |
| Customer switching | Manual or delayed | Automatic and fast | Depends on the customer's device. |
| Loss rate | Up to 50%. | Minimum (if there is a dedicated channel) | No losses (gigabit port) |
| Required cable | No. | No (or eat for backhaul) | I'll be sure. |
A major advantage of Mesh is that it can manage the entire network through one app, you can see which device is connected to which point, and if necessary, limit access. In addition, modern Xiaomi routers with Wi-Fi 6 support use a dedicated channel for communication between nodes, which minimizes speed losses.
💡
Mesh-system is the ideal solution for large apartments, where it is important to save video and online games when moving between rooms without connection breaks.
Static IP and DHCP configuration to avoid conflicts
One of the most common mistakes when creating a network of two routers is conflict. DHCP-If both devices try to distribute IP-So the second router, the repeater, you need to set up the local network correctly. LAN second-way.
Change. IP-The router's address is the router's address so that it is in the main subnet, but not the same as it. For example, if the main router has the address 192.168.31.1, the second one should ask 192.168.31.2. This will allow you to easily get into its settings in the future, knowing the exact address.
The most important thing is to turn off the DHCP server on the second router, which is a function that only the main router should perform. If you use Wi-Fi relay mode through the regular menu, the system often does this automatically, but in Access Point (AP) mode or when you manually configure WDS, disabling DHCP is a must.
⚠️ Attention: After disconnection DHCP on the second router and save settings, you may lose access to its web interface if your computer receives IP-The address is from the main router, and they're on different subnets. IP-addresses are in the same range before disconnection DHCP.
Once you've set the settings, restart both devices. First, turn on the main router and wait for the full load, then turn on the repeater. Check the connection on the client devices.
Optimization of location and frequency ranges
Proper physical placement of the repeater is critical to its efficient operation. Many users make the mistake of putting the amplifier in the same room where there is no signal. This is wrong: the repeater must be in the zone of confident reception of the main signal, but closer to the problem area.
The ideal placement point is in the middle between the main router and the place where the Internet is needed, and if the repeater picks up a signal with a single stick, it will broadcast a signal that is also weak and unstable, despite the full scale on your phone.
💡
Use the “Communication Quality Assessment” feature in the Mi Home app (if available for your model) or simply check the speed through Speedtest at different points to find the optimal location for the repeater installation.
Also worth paying attention to frequency bands. If possible, set up communication between routers at 5 GHz, as it is less noisy and provides higher speeds. However, 5 GHz is worse through walls. If the main router is far away, you may have to use 2.4 GHz to communicate between nodes, leaving 5 GHz for distribution to customers.
Frequent problems and ways to solve them
Users may encounter a number of typical problems during the setup process, such as devices that may not see the repeater network or constantly switch between access points, causing a "ping-pong" effect. Often this is solved by channel separation: if the main router is running on channel 1, the repeater (if it is not in Mesh mode) should specify the channel 6 or 11 so that they do not jam each other.
Another problem is low speed on the repeater, which can be caused by the device operating in half-duplex mode (simultaneously receives and transmits on the same frequency), the solution is one: use routers with dual-band mode and configure backhol (communication between routers) on a separate frequency or use a cable.
- 📡 Problem: The router is not connecting to the main network.Solution: Check the Wi-Fi password, make sure the main router does not use filtering over the main network. MAC-address.
- 🔌 Problem: No Internet access via repeater. Solution: Check if it's offline. DHCP on the second router and whether the gateways (Gateway) coincide with the main router.
- 📶 Problem: Low data rate. Solution: Try repositioning antennas or switching the broadcast channel to a less busy one.
- 🔄 Problem: Devices don't switch to repeater Solution: Manual mode, this is normal; automatic switching requires setting up Mesh or the same network names with caution.
If nothing works, try resetting both devices completely and resetting the network from the main router, sometimes software failures in the configuration require a clean installation.
