How to connect the second router to the Xiaomi router over Wi-Fi: 3 proven ways

Expanding Wi-Fi coverage in your home or office is a challenge for most Xiaomi routers, and if your main router can’t keep up with the space and the second device can’t be wired, wireless routers can be the best solution, allowing you to create a single network without laying cables and losing functionality.

In this article, we will discuss three main ways to connect the second router to Xiaomi over Wi-Fi: Bridge mode (WDS), Repeater and client connectivity: Each method has its own characteristics, advantages and limitations, so you can choose the best option depending on your hardware model and network requirements. Particular attention will be paid to the settings of the firmware MiWiFi, which is used in most of the brand’s routers, including the popular Mi Router series. 4A/4C/4Q, AX3600 and AX6000.

Before you start setting up, make sure that both routers support the selected connection mode. WDS-Bridges require Wi-Fi compatibility (better to use) 802.11ac or 802.11ax), And for repeater mode, you have Repeater in the second device's web interface: SSID, passcode.

1.Equipment Preparation: What to Know Before Setup

Before connecting two routers over Wi-Fi, you need to do a few preparatory steps to avoid common mistakes, such as conflict. IP-addresses or unstable connection.

First, check the hardware compatibility of the devices. Xiaomi routers new series (AX1800, AX3000, AX5000) The three modes of connection are usually supported, whereas the budget models (Mi Router) 3G, Mini) may have limitations, such as in Mi Router 4A Gigabit Edition does not have a built-in repeater feature, but is available WDS-bridge.

Second, update the firmware on both devices.

• 🔄 Go to the router web interface (192.168.31.1 or miwifi.com).
• 📥 In the Update section (System) → Firmware Update - Check the Update of the Software Version.
• ⚡ If you have updates, install them while waiting for the reboot.

It is also recommended to reset the second router to factory if it was previously used on another network, this will eliminate configuration conflicts.

2. Method 1: Connecting through WDS-bridge (bridge mode)

WDS-The Wireless Distribution System is a technology that allows two routers to be connected to a single network at the channel level, and the main advantage of the method is that both devices retain the same network. SSID (network name, and connected clients automatically switch between them depending on the signal level (roaming), but the connection speed in this mode is reduced by about 30-50% due to double data transfer.

To set up WDS-bridge on Xiaomi router:

1. Connect to the main router’s web interface (miwifi.com) and go to the Wi-Fi section → Wi-Fi settings.
2. Remember or write down: 📡 Name of the network (SSID); 🔐 Password; 📶 Channel (e.g. 6 or Auto); 🛡️ Type of encryption (WPA2-PSK or WPA3).

After saving the settings, both routers will restart. Check the connection: connect the device (smartphone, laptop) to the network and make sure that IP-The address is correctly provided (e.g. via ipconfig command in Windows). If there is no Internet connection, check the settings. LAN-Ports – may need to be changed IP second router manually (for example, on 192.168.31.2, if the main has 192.168.31.1).

Method 2: Repeater mode (Repeater)

If your second router supports Repeater, this method will be the easiest way to expand coverage. WDS, Here, the second router creates a separate network with a different name (for example, the network is a separate router, MiWiFi_5G_EXT), But it uses the Internet of the main device.

Instructions for Xiaomi routers with Repeater support (for example, Mi Router) 4C, AX1800):

1. Reset the second router to factory settings (Reset button).
2. Connect to its default network (name is indicated on the sticker, password is usually missing).
3. In the web interface (miwifi.com) select Mode → Repeater (Repeater).
4. In the list of available networks, find the main Xiaomi router and connect to it by entering a password.
5. Save the settings and wait for the reboot.

Method 3: Wi-Fi Client (Customer)

Wi-Fi Client mode is suitable if the second router must connect to the main as a normal device (for example, to distribute the Internet via cable to a computer or a computer). IP-In this case, the second router does not relay Wi-Fi, but only provides access to the network through its own network. LAN-port.

Set up for Xiaomi routers:

1. Connect to the second router and go to Settings → Mode of work.
2. Choose a Client or Wi-Fi Client.
3. In the list of networks, find the main Xiaomi router and connect by specifying the password.
4. Turn it off. DHCP-server and assign a static router to the second router IP in the main subnet (for example, 192.168.31.100).
5. Connect devices (PC, console, camera) to LAN-port.

This method is convenient for connecting wired devices in remote rooms where it is difficult to lay a cable from the main router.

• 🚫 The second router will not give out Wi-Fi;
• 🔌 All customers must connect via cable;
• ⚡ Speed depends on the quality of the signal between routers.

💡

If the second router does not support Client mode, you can use an alternative method: connect it to the main Wi-Fi as a normal device (via a regular device). WPS or enter a password, then turn off DHCP And connect customers to it. LAN-port.

5. Comparison of Connection Methods: Which One Should You Choose?

To determine the optimal way to connect two Xiaomi routers over Wi-Fi, compare the key parameters of each method:

Critical nuance for Xiaomi routers: in the firmware MiWiFi mode WDS It can be unstable if the main and second routers use different Wi-Fi standards (for example, the main router is not connected to the Internet, 802.11n and 802.11ac). In this case, it is recommended to manually specify the same channel and bandwidth (20/40 MHz) on both devices.

The choice of method depends on your tasks:

• 🏠 For a house with a large area and many devices — WDS-bridge;
• 📱 Temporary amplification of the signal in a separate room – Repeater;
• 🖥️ For connecting wired devices (PCs, NAS) — Wi-Fi Client.

Typical errors and their solution

When you set up a second router over Wi-Fi, users often face problems, and let's look at the most common ones and how to fix them.

Problem 1: The second router is not connected to the main router.

⚠️ Note: If you are setting up WDS Repeater second router does not see the main network, check: 📶 Compatibility of Wi-Fi standards (e.g, 802.11ac and 802.11n may not connect); 🔒 Type of encryption (if the main router uses the WPA3, The second one only supports WPA2, connection will be impossible); 🔄 Broadcast channel (both routers must have the same channel or Auto).

Problem 2: No Internet access after you connect.

The reasons may be as follows:

• 🔌 Conflict IP-Addresses (Make sure the second router is disabled) DHCP or IP subnet);
• 🌐 Wrong settings DNS (Try to manually DNS Google: 8.8.8.8 and 8.8.4.4);
• 🔄 Unsaved settings (after changing the settings, always click Save and wait for the reboot).

Problem 3: Low speed or breakage of the connection.

To improve stability:

• 📡 Reduce the distance between routers or use directional antennas;
• 🔄 Switch to a less loaded channel (use applications like Wi-Fi Analyzer to analyze the airwaves);
• 🛡️ Turn off energy savings on client devices (in Wi-Fi adapter settings).

💡

If the second router Xiaomi does not support WDS Or Repeater, try alternative firmware (like OpenWRT or Padavan.

7. Network optimization after connection

After successfully connecting two routers, it is recommended to follow several steps to optimize the network:

1. Configuring channels and frequencies.

If both routers are running at 2.4 GHz, set fixed channels 5 units apart (e.g. 1 and 6) to avoid interference. For 5 GHz, choose non-intersecting channels (36, 40, 44, 48, etc.).

2. Update of the network name (SSID).

If you use WDS-bridge, leave the same network name on both routers. For Repeater, add a suffix (e.g., add a suffix, _EXT), So, to distinguish the main network from the extended network:

• 📡 Main router: MiWiFi_5G;
• 📡 Repeater: MiWiFi_5G_EXT.

3. Device Priority Setup (QoS).

In the web interface of the main router (miwifi.com) → Settings → QoS: High priority for devices that are sensitive to delays (e.g. Smart) TV, This will help avoid lags when streaming or online gaming.

4. Network monitoring.

Use Xiaomi’s built-in tools or third-party apps (like Fing) to track:

• 📊 Channel loading;
• 📱 Number of connected devices;
• ⚡ Connection speed between routers.
