How to set up the Xiaomi Mi Router 4 router in repeater mode

The problem of “dead zones” in the apartment or house is familiar to many users: the main router installed in the corridor, physically can not break through thick walls and provide a stable signal in distant rooms. In such situations, buying new expensive equipment is often not necessary, especially if you have an old Xiaomi Router 4. This compact gadget can be a great wireless amplifier if you set its mode of operation.

Using the Wi-Fi Router 4 as a repeater can significantly extend the range of your home network without having to lay any extra cables, which is ideal for those who want to get coverage on the balcony, in the garage or just in the bedroom, where the main signal is difficult to get.

In this guide, we will discuss in detail all the steps in turning your Xiaomi router into a powerful signal repeater. We will not only look at standard methods through the web interface, but also touch on the nuances that are often silent in official instructions. The key point is the firmware version, since the functionality may differ depending on the regional modification of the device.

Preparation of equipment and compatibility check

Before you start setting up directly, you need to make sure your hardware is ready to work in extended mode. Not all Xiaomi Mi Router 4 modifications have the same feature set out of the box, especially if it is a global version or Chinese imports. First of all, check the model on the bottom of the device - it can be the standard version, 4A, 4C or 4G.

You will need the router itself, which will work as a repeater, and access to the main router that distributes the Internet. It is desirable that both devices support 802.11n or 802.11ac standards for maximum data transfer speed. If you plan to use dual-band mode, make sure that the main router also broadcasts the network in the 5 GHz band.

⚠️ Warning: Before all manipulations are started, it is recommended to reset the repeater to factory settings completely, eliminating conflicts of old configurations and IP-Addresses that may prevent you from connecting to a new network.

It is also worth knowing in advance the parameters of your main network: the type of encryption (usually WPA2-PSK) and the password from Wi-Fi. Without this information, the repeater cannot be set up, since it will need to “friend” the main router. If you do not remember the password, you can see it in the settings of the connected computer or in the interface of the main router.

Resetting settings and entering the control panel

The first technical step is to clear the device’s memory from previous settings. Find a small hole on the Xiaomi router body that says Reset. Put the device in the socket and wait for the boot to complete (the indicator should stop blinking or burning with even light).

Using a paper clip or a special needle, press the button inside the hole and hold it for 5-10 seconds. The indicators on the front panel should start flashing often, which signals the beginning of the process of restoring factory parameters.

Now you need to connect to the control of the device. Take a smartphone or laptop and find in the list of available Wi-Fi networks with the name Xiaomi_XXXX or MiWiFi_XXXX. Connect to it (the default password is not, or it is listed on the sticker under the device). Open any browser and enter a standard address in the address bar: 192.168.31.1 or miwifi.com.

• 📱 Connect the computer with a cable LAN to the port with yellow marking for a more stable connection during the initial setting.
• 🌐 If 192.168.31.1 is not opened, check the network card settings — IP-The address must be automatically received (DHCP).
• 🔑 When you first log in, the system may require you to create a new administrator password — write it down, it will be needed for future changes.
• 🌍 Select the “Russia” or “Europe” region if the interface offers a choice to get the correct time and frequency channel settings.

Once you've successfully logged in, you'll see a start page where the router will suggest you configure the Internet. While you ignore the provider's requirements, our goal is to get into the advanced settings menu. WAN-Select the option “Skip” or “Set up later».

Search and activation of repeater mode

The MiWiFi OS firmware interface can hide the repeater mode depending on the version. In the classic menu, go to Settings (cog icon) and select the Operating Mode or System Status tab, and there should be options: "Router", "Repeater" and sometimes "Access Point".

If you don't see an explicit mode switch, your firmware version may require manual activation through the Wi-Fi menu. Go to Wi-Fi Settings and look for Scan Networks or Connect to Wi-Fi. The logic here is that the router should find your main network and connect to it as a client, while also distributing the signal further.

Select Wi-Fi Repeater mode. The system will ask you to select the network to be strengthened. The list will show all available Wi-Fi networks in range. Find the name of your main router and click on it.

Configuring the parameters of the wireless network

Once you have selected the main network to be amplified, the system will ask you to enter your password, enter the security key of your main router, and here lies an important nuance: for the devices to work seamlessly, the best thing to do is to specify the name of the new network (SSID) and password exactly the same as on the main router.

If you keep the names the same, conflicts can arise. IP-addresses, if DHCP-The server is turned on on on both devices. In repeater mode, the Xiaomi Router 4 usually automatically disables its own server. DHCP-server, transferring this function to the main router. Check this in the Settings section LAN.

If you want to be able to easily switch between devices or diagnose a network, you can specify the name of the repeater network with the prefix " Ext" (for example, the name of the network is used for the network, Home_WiFi_Ext). This will allow you to manually choose which access point to connect to, which sometimes gives you a more stable speed than automatic roaming of budget devices.

• 📡 Install a Wi-Fi channel manually (e.g. 1, 6 or 11 for 2.4GHz) to match the main router, avoiding automatic selection.
• 🔒 Use a type of encryption WPA2-PSK (AES), It is the most compatible standard for all devices.
• 🚫 Disable the guest network on the repeater, if it is not needed, so as not to create an unnecessary load on the processor and ether.
• 📶 Place the repeater at a distance where the main router signal is still good (2-3 scale, but is close to the coverage area.

⚠️ Warning: Don't put the repeater in the dead zone where the main signal barely reaches. The repeater doesn't create a signal out of nothing, it just relays what it receives. If the input is bad, it will get worse at the output.

Advanced settings and speed optimization

For users who want to make the most of the router bundle, additional settings are available. In the Wi-Fi Settings menu -> You can also find the channel width option. For the 2.4 GHz range, it is recommended to set 20 MHz if there are many neighbor networks in the apartment, or 40 MHz if the air is free.

Signal power is also adjustable, and in System -> Signal settings (if available in your firmware version), you can set a High or Max value, which will increase power consumption and heating, but improve the penetration of walls.

The frequency choice is important. The 5GHz range provides high speed but has a short range and does not pass through walls well. If your Xiaomi Mi Router 4 is dual-band, set the repeater to work at 5GHz to communicate with the main router (Backhaul), and leave 2.4GHz for customers if the devices are old.

Be sure to check if MU-MIMO is enabled (if supported by both routers) is a technology that allows you to transfer data to multiple devices simultaneously, which is critical for modern smartphones and Smart TVs.

Checking the efficiency and eliminating problems

After you have applied all the settings, the router will restart. The status indicator should light up in blue or green (depending on the model), which means a successful Internet connection. Check the connection by connecting the smartphone to the repeater network and running a speed test.

If the speed is significantly lower than expected (less than 50% of the speed of the main channel), try to change the position of the repeater, perhaps it is too far from the source of the signal or, conversely, too close, creating interference.

A common problem is the reconnection cycle, where devices are constantly switching between the main router and the repeater, whether it is by reducing the transmitter power on the main router or spreading the network names (SSID) so that you can choose your own entry point.

• 🔄 Reboot both routers in turn: first turn off the repeater, then the main, turn on the main, wait for the load, then turn on the repeater.
• 📉 Check the loading of channels with WiFi Analyzer and switch to a less loaded frequency channel.
• 🔌 Make sure the repeater power supply is in good working order – a lack of voltage can cause the Wi-Fi module to work unstablely.

💡

Use the Mi WiFi app for your smartphone – it can automatically find a router on the network and offer optimal settings, even if web interests seem complicated.
