How to connect two Xiaomi routers: 3 proven ways + mistake-making

Connecting two Xiaomi routers into a single network is a challenge faced by owners of large apartments, private homes or offices. AX6000 or Redmi Router AX5 The problem is compounded when walls are made of concrete or metal structures that effectively shield Wi-Fi.

In this article, we will discuss three working methods of connection: via cable (the most reliable), Wi-Fi (without wires), and using Mesh technology (for modern models). Each method has its own nuances, so we will discuss in detail the settings, possible errors and how to fix them. Particular attention will be paid to model compatibility - not all Xiaomi routers support repeater or Mesh mode.

If you want to not only expand the coverage area, but also optimize the load on the network (for example, for streaming). 4K And if you want to play games online, you need to choose the right way to connect, like, you know, a cable connection minimizes delays, and the Mesh automatically switches devices between access points.

1. Preparation for the integration of routers: what to check

Before you start setting up, make sure that both routers are compatible with each other.Some Xiaomi models (such as the old Mi Router 3 or Mi Router) 4C) They don't support repeater or mesh. Here's what you need to do in advance:

βœ… Check firmware versions. Outdated software can cause crashes. Update routers through the Mi Wi-Fi app (Settings section) β†’ Update of firmware? Up-to-date versions for popular models:

  • πŸ“± Xiaomi Router AX6000 β€” not less than 1.2.34
  • πŸ“± Redmi Router AX5 β€” not less than 1.1.28
  • πŸ“± Xiaomi Router 4A Gigabit - not less than 2.2.106

βœ… Identify the main and auxiliary router. The main (also the main) will distribute IP-And the other one is to expand the network, and the other one is to use a more powerful model, for example, AX6000 instead 4A).

βœ… Prepare the cable or check the distance. If you plan to connect routers over Wi-Fi, make sure they are in the zone of a confident signal (no more than 10 meters if there are no obstacles). LAN-Cat-type 5e or higher (length up to 100 meters).

What cables are suitable for connecting routers?
For connecting routers, any twisted pair is suitable not below the Cat category 5e (speeds up to 1 Gbps Cat 6 (up to 10 Gbps at distances up to 55 m) is recommended for models with ports 2.5G or 5G, For example, Xiaomi Router AX9000. Avoid damaged or twisted cables – this leads to packet loss and unstable connection.

2. Method 1: Connection via cable (bridge or LAN-to-LAN)

This is the most reliable method, as it eliminates signal loss and delay, suitable for any Xiaomi models, including the old Mi Router 3 or the new model. 4C. The essence of the method: the second router connects to the first through the port LAN (not WAN!) and operates in access point mode (AP).

Step-by-step:

  1. Connect routers with cable: one end at any LAN-port of the main router, the other in LAN-port of auxiliary (not WAN!).
  2. Open the web interface of the auxiliary router at 192.168.31.1 (or miwifi.com).
  3. Go to Settings. β†’ Extended. β†’ Mode and select Access Point Mode (AP).
  4. In the field IP-address: provide a free address from the main router subnet (for example, if the main one distributes 192.168.31.1, specify 192.168.31.2).
  5. Turn it off. DHCP-server on the auxiliary router (to IP handed out only the main).
  6. Save the settings and restart both devices.

⚠️ Note: If the Internet does not work after connecting, check:

  • πŸ”Œ Is the cable connected correctly (LANβ†’LAN, not LANβ†’WAN).
  • πŸ“Ά Aren't they in conflict? IP-Addresses (main and secondary routers should not be the same) IP).
  • πŸ”„ Is it off? DHCP router.

Cable is connected to LAN-port WAN!)

IP-Router addresses do not conflict

DHCP disabled on the auxiliary router

SSID The network password is the same (optional)

-->

Critical nuance: if the auxiliary router does not support the mode AP, Use an alternative method – manually adjusting by switching off DHCP and assignment of static IP.

Method 2: Wireless connection (repeater mode)

If you're not comfortable laying the cable, you can combine the routers over Wi-Fi. To do this, the auxiliary router must support Repeater mode. Unfortunately, not all Xiaomi models have this feature in standard firmware. 4A It's supported by Mi Router. 3G β€” no.

How to set the repeater mode:

  1. Connect to the auxiliary router via Wi-Fi or cable.
  2. Open the web interface (192.168.31.1) and go to Settings β†’ Mode of work.
  3. Select the Repeater Mode.
  4. In the list of available networks, select SSID main router and enter its password.
  5. Set up. SSID password for the extended network (you can leave the same as the main router, or come up with new ones).
  6. Save the settings and wait for the reboot.

⚠️ Note: With this connection, the Wi-Fi speed will decrease by at least 2 times, since the auxiliary router simultaneously receives and transmits a signal. For example, if the main router is distributing 300 Mbps, after the repeater will remain ~150 Mbps.

Advantages and disadvantages of the method:

PlusesCons
βœ… No need for cable.❌ Speed drop 50%
βœ… Quick setup❌ Possible communication breaks with a weak signal
βœ… Suitable for rented housing❌ Not all Xiaomi models support Repeater

πŸ’‘

If your router doesn’t support Repeater mode, try alternative firmware like OpenWRT or Padavan, but this requires technical skills and may be unwarranted.

Method 3: Mesh network (for modern models)

Mesh technology allows for a seamless network where devices automatically switch between routers without breaking the connection, ideal for larger homes, but requires Mesh support from both models. In 2026, Mesh supports:

  • πŸ“‘ Xiaomi Router AX6000 (basic + supportive)
  • πŸ“‘ Redmi Router AX5 (only paired with AX6000)
  • πŸ“‘ Xiaomi Router BE7000 (full-fledged Mesh system)

How to set up a Mesh network:

  1. Make sure both routers are updated to the latest firmware.
  2. Connect the auxiliary router to the power and wait for it to load.
  3. Open the Mi Wi-Fi app on your smartphone.
  4. Go to the Devices section β†’ Add a Mesh device.
  5. Follow the instructions on the screen: the application will find the second router and offer to combine them into Mesh.
  6. Wait for the synchronization (can take up to 5 minutes).

⚠️ Note: In the Mesh network, the auxiliary router must be in the zone of the main signal (at least 70% of the level). If the signal is weak, the Mesh will constantly reconnect, which will lead to lags.

How is Mesh better than a regular repeater?

  • πŸ”„ Seamless roaming: devices automatically switch between routers without breaking the connection.
  • πŸ“Ά Signal optimization: the system chooses the best channel and transmission power.
  • πŸ›‘οΈ Single network: one SSID Password for all access points.

πŸ’‘

Mesh network is the best choice for homes with an area of 100 m2, where connection stability is important (for example, for smart homes or video surveillance).

5. Common mistakes and their solution

Even with the right setup, there can be problems.-5 errors and ways of eliminating them:

πŸ”΄ No Internet on the secondary router:

  • Check if it's off. DHCP assisted.
  • Make sure that IP-addresses do not conflict (e.g., basic 192.168.31.1, auxiliary 192.168.31.2).
  • If the cable connection is damaged, check if it is damaged (try another cable).

πŸ”΄ Weak Wi-Fi signal after the merger:

  • Change the Wi-Fi channel in the main router settings (select the least loaded in the Wi-Fi Analyzer app).
  • Reduce the transmission power if the routers are too close (may cause interference).
  • For the Mesh network, check the distance between the nodes (optimally 5-10 meters).

πŸ”΄ Devices do not switch between routers (in Mesh):

  • Update the firmware on both routers.
  • Enable the option of Fast Roaming (802.11r) wifi-based.
  • Make sure that both routers are the same. SSID, password and channel.

πŸ”΄ Low speed when connected via repeater:

  • This is normal for Repeater mode - the speed drops by 2 times. Solution: use cable or Mesh.
  • Try switching the main router to the 5GHz band (if the auxiliary supports it).

πŸ”΄ Routers "can't see each other:

  • Check whether the main router is enabled compatibility mode (in some firmware you need to turn off filtering) MAC-address).
  • Reset the auxiliary router settings to the factory (reset button for 10 seconds).
What if the router does not open the web interface?
1. Check if your computer/phone is connected to your router via cable or Wi-Fi. 2. Try alternative addresses: miwifi.com, 192.168.0.1 or 192.168.1.1. 3. Reset the router to factory settings (Reset button on the back). 4. Disable the antivirus or VPN β€” They can block access.

6. Network optimization after integration

After successfully connecting routers, we recommend following several steps for maximum performance:

πŸ”§ Setting up Wi-Fi channels:

  • Use the Wi-Fi Analyzer (Android) or NetSpot app (iOS/macOS), Find the least congested channel.
  • For the 2.4 GHz band, choose channels 1, 6, or 11 (they don't overlap).
  • For 5GHz, choose channels with numbers 36-48 or 149-165 (depending on the region).

πŸ”§ Separation of loads by band:

  • Assign 2.4 GHz to low-bandwidth devices (smart lamps, sensors).
  • Use 5 GHz for demanding devices (laptops, TV, game console).

πŸ”§ QoS (Quality of Service):

  • Enable QoS in the main router settings (Extended section) β†’ QoS).
  • Prioritize traffic for video (YouTube, Netflix) or games (Steam, PlayStation).

πŸ”§ Firmware update:

  • Check for updates regularly through the Mi Wi-Fi app.
  • Newer firmware versions often improve the stability of Mesh and repeaters.

πŸ’‘

If you have a lot of devices on the network (20)+), Consider the possibility of splitting the network into VLAN Or using guest Wi-Fi for IoT devices (smart lamps, cameras) to reduce the load on the main network.

7. Alternatives: When two routers are not the solution

Sometimes combining two routers doesn't solve the problem of a weak signal.

πŸ“Ά Wi-Fi amplifier (repiter):

  • It is easier to set up than the second router.
  • It is suitable for small "dead zones".
  • Examples: Xiaomi Wi-Fi Repeater 2, TP-Link RE605X.

πŸ“‘ Mesh system from Xiaomi:

  • Ready-made solutions like Xiaomi Mesh System AX3000 (2 or 3 knots).
  • It is easier to set up than a homemade Mesh of two routers.
  • Supports seamless roaming and channel optimization.

πŸ”Œ Powerline adapters:

  • Transmit the Internet via electrical wiring (no need to lay cables).
  • Suitable for houses with thick walls.
  • Examples: TP-Link AV1000, Xiaomi Powerline Adapter.

πŸ“± Mobile. 4G/5G router:

  • If the problem is poor wired internet, not Wi-Fi coverage.
  • Examples: Xiaomi Mi Router 4G, Huawei 5G CPE Pro 2.

FAQ: Frequent questions about combining Xiaomi routers

❓ Can you connect Xiaomi and TP-Link routers?
Yes, but with reservations, there will be no problem with the LAN-to-LAN connection, as long as it is not too difficult. IP-For a wireless connection (Repeater), you need to make sure that the TP-Link router supports repeater mode for Xiaomi networks (sometimes there are problems with encryption). Mesh network between different brands can not be configured.
❓ Why after the merger, the speed fell by 2 times?
This is normal for repeater mode, as the router simultaneously receives and transmits a signal, dividing the bandwidth in half. Solutions: Use a cable connection (LAN-to-LAN). Switch to Mesh (if routers support). Use the 5 GHz band instead of 2.4 GHz band (if devices support).
❓ How to make sure both routers have one SSID?
For this purpose: Install the same on the auxiliary router SSID Make sure that the Wi-Fi channels do not overlap (for example, the main channel). 1, sub- 6). Mesh network one. SSID set up automatically. ⚠️ Attention: Equally SSID Devices can stick on one router even if the signal of the other is stronger (802.11r/k/v) wifi-based.
❓ Can I use the second router as a switch?
For this: Connect the cable to LAN-port β†’ LAN-port of auxiliary (not WAN!). Turn it off. DHCP And Wi-Fi on the back-up router. IP Now the auxiliary router will work like a regular switch, distributing the Internet over the cable.
❓ Why devices don’t switch automatically on a Mesh network?
Possible causes and solutions: πŸ”Ή Routers are different SSID or passwords – check the settings. πŸ”Ή Lack of support 802.11r/k/v β€” Enable these options in your Wi-Fi settings. πŸ”Ή Weak signal between nodes – move routers closer together. πŸ”Ή Outdated firmware – update both routers.
