How to turn a Xiaomi router into a Wi-Fi repeater: full instructions with nuances

You want to expand your Wi-Fi coverage but don’t know how to make a Xiaomi router work like a repeater?This article will help you understand the nuances of setting up a repeater mode on your brand’s devices, from model compatibility to solving typical problems. We’ll look at official methods through the web interface and the Mi Wi-Fi mobile application, as well as alternative ways for advanced users.

It is important to understand that not all Xiaomi routers support out-of-the-box relaying, such as the popular Mi Router models. 4A Mi Router 4C Require firmware with alternative software (like OpenWRT), whereas Xiaomi AX3600 or Mi Router AC2100 They have a built-in option. In this article, you'll find a compatibility table and detailed instructions for each case, from simple to complex.

If your router doesn't support the relay mode natively, don't get upset. We'll show you how to get around this restriction with minimal risks from using the bridge. WDS And for those of you who are afraid of breaking the device, here's a training checklist and a way to roll back changes.

What Xiaomi routers support the relay mode

Before you start setting up, make sure your model is capable of working like a repeater. Xiaomi divides devices into three categories to support this feature:

• ✅ Full support: Mi Router AX3600, Mi Router AC2100, Mi Router 4 Pro, Redmi Router AX5 — Have built-in "Repeater" mode in the official firmware.
• ⚠️ Partial support: Mi Router 3G/3C, Mi Router 4 — require manual adjustment through WDS client-mode.
• ❌ Unsupported: Mi Router 4A (100M/300M Mi Router Mini - you need custom firmware (OpenWRT, Padavan).

To accurately determine your model, look at the sticker on the bottom of the device or check in the web interface (192.168.31.1) section Status → Note: Even if your router falls into the first category, the repeater function may be blocked in some regional versions of the firmware (e.g. China), which will require a change of region or software update.

If your model is not in the table, check it on the official Xiaomi website or in thematic communities (for example, in the case of the model, 4PDA). For devices without official support, we recommend considering alternative solutions, such as using a second router in client mode (connecting via cable to the main one).

Preparation of Xiaomi router for relay configuration

Before you put your device into repeater mode, follow a few mandatory steps to avoid common mistakes, such as losing access to the web interface or conflicts. IP-address.

Update the router to the latest version

Reset the settings to factory (Reset button)

Connect the router to the PC/laptop via cable

Write down the main network data (SSID, password, channel)

Turn it off. VPN/proxy on the setting device-->

Pay special attention to resetting.

1. Press and hold the Reset button (usually located on the back) for 10-15 seconds.
2. Wait until the indicators start flashing – this is a signal of a successful reset.
3. Connect to the router network via cable or Wi-Fi (network name by default: Xiaomi_XXXX, password is on the sticker).

If you plan to configure a repeater through the Mi Wi-Fi mobile app, make sure that:

• ✅ The app is updated to the latest version (check in Google Play or App Store).
• ✅ Your smartphone is connected to the router network, which will be the main (not to what will become a repeater).
• ✅ In the phone settings turned off power saving mode for the Mi Wi-Fi application.

⚠️ Note: If your Xiaomi router has previously been used in bridge or access point mode, return it to router mode via the web interface before setting up the repeater (Mode of operation). → Router: Otherwise, the repeater option may not be available.

Set up a repeater via a web interface (for supported models)

This method is suitable for routers with official repeater mode support, such as Mi Router. AX3600 or Redmi Router AX5. The instructions are relevant for firmware versions 2.0.100 and later.

Step. 1. Connect to the router, which you will configure as a repeater, via cable or Wi-Fi. Open the browser and enter the address. 192.168.31.1 (or miwifi.com. log in with your login and password (default — admin/sticker).

Step 2. Go to the Additional Settings section → Select the Repeater option and click Next.

Step 3: The router will automatically scan the networks available, select the one you want to expand from the list, and enter the password (SSID not broadcasted), click Add manually and enter the network name (SSID) password.

Step 4: Configure the repeater settings:

• ✅ Relay network name: can be left as the main network or added a suffix (e.g, MyWiFi_Ext).
• ✅ Channel: Select Auto or specify the same channel as the main router (check in its settings).
• ✅ Safety: We recommend leaving WPA2-PSK (mainline).

Step 5: Save the settings and wait for the device to restart (it will take 1-2 minutes), after which the Xiaomi router will broadcast the extended network, connect to it and check the speed through the Speedtest service.

💡

If after setting up the repeater "loses" communication with the main router, try manually specifying static IP-address in the range of the main network (for example, 192.168.31.250) in the local network settings → DHCP main-route.

Configure via the Mi Wi-Fi mobile application

Mi Wi-Fi offers a more intuitive interface for setting up a repeater, but has limitations. 4A) the application does not display the repeater option, even if it is available through the web interface.

Step 1: Install the Mi Wi-Fi app on your smartphone (links: Android/IOS). Connect your phone to the router network, which will be the repeater.

Step 2. Open the app and select your device. Go to Settings. → Mode of work → Repiter. If you don't have an option, update your router's firmware through System settings. → Update of the PO.

Step 3: The app will prompt you to select the main network from the list, if your network is not listed:

• ✅ Make sure the main router is on and broadcasting SSID.
• ✅ Check that the network is operating in the 2.4 GHz band (some Xiaomi models do not support 5 GHz relay).
• ✅ Reboot both routers.

Step 4. Once you select a network, enter your password and set up your repeater settings (similar to the web interface). Note that there is no manual channel option in the Mi Wi-Fi app – it is selected automatically, which can lead to conflicts if the main router uses a fixed channel.

⚠️ Warning: If the repeater doesn't connect to the main network after setting up the app, try resetting it to factory settings and repeating the process via the web interface.The Mi Wi-Fi app sometimes keeps the settings incorrect, especially on Android 12+.

Alternative methods: WDS and client-centered

If your Xiaomi router does not support native relay mode, you can use the bridge WDS These methods are more complex, but they work on most models, including the Mi Router 4 and Mi Router. 3G.

Method 1: Adjustment WDS-bridge

WDS (Wireless Distribution System allows you to connect two routers over Wi-Fi without repeater mode, and the disadvantage of the method is a speed reduction of about 50% due to dual data transfer.

Step 1. Connect to the router's web interface, which will be the repeater (192.168.31.1). → Wireless mode → Settings WDS.

Step 2. Click Scan and select the main network. Enter its password and save the settings. Important: the main router must also support the main network. WDS (Set it up similarly if required).

Step 3. Turn it off. DHCP-server on the repeater (Local network) → DHCP), avoiding conflict IP-Give him a static address. IP over the main network (e.g. 192.168.31.250).

Method 2: Client mode (for advanced)

This method involves the repeater connecting to the main network as a client and then distributing the Internet through its Wi-Fi or ports. LAN. Suitable for models without WDS.

Step 1. In the relay web interface, go to Additional Settings → Wireless mode. Enable the option to Enable Client Mode (or Client Mode in English firmware).

Step 2: Connect to the main network by entering it SSID and the password. DHCP Relay it to the repeater and assign it a static IP.

Step 3: Connect devices to the repeater via cable or Wi-Fi (if the Access Point option is enabled). WDS, stability higher.

💡

If your router does not support any of the official methods, consider running alternative software (such as OpenWRT).

Solving typical problems when setting up a repeater

Even if set up properly, Xiaomi’s repeater can be unstable, and let’s look at the most common problems and how to fix them.

Problem 1: The repeater is not connected to the main network

Causes and solutions:

• 🔄 Wi-Fi Standards Disparate: Make sure the main router is running in mode 802.11n or 802.11ac (not 802.11b/g). In the main router settings, select Mixed Mode (n/ac).
• 🔒 Wrong password: Recheck the password of the main network if it contains special characters (for example, #, $), Try changing it to a simple one (e.g. 12345678) for the test.
• 📡 Weak signal: Place the repeater closer to the main router (no more than 10 meters away). Use the Wi-Fi Analyzer app to check signal strength.

Problem 2: Low speed or breakage of connection

What to do:

• 📶 Change channel: In the main router settings, select a fixed channel (for example, 6 or 11 for 2.4 GHz) instead of Auto.
• 🔄 Turn off energy savings: In the repeater settings, find the Wi-Fi Energy Saving option and turn it off.
• 🛠️ Update the firmware: Check for updates for both routers. for Xiaomi, this is done through System Settings → Update of the PO.

Problem 3: Devices do not connect to the repeater

Possible causes:

• 🔧 Conflict IP: Turn it off. DHCP Relay it to the repeater and assign it a static IP off-roader.
• 🔒 Incorrect type of security: Make sure the relay has the same type of encryption as the main router (WPA2-PSK recommended).
• 📵 Hidden SSID: If the main network is hidden, the repeater may mistranslate its name.

⚠️ Note: If the Xiaomi repeater after setting up gives an error "failed to connect to the network", reset it to the factory settings and repeat the process, previously disabling the Safe Wi-Fi or Connection Protection function on the main router (if there is one).

Optimization of the work of the Xiaomi repeater

To ensure that the repeater is stable and provides maximum speed, follow these recommendations:

Optimal accommodation:

• 📍 Place the repeater half the distance between the main router and the dead zone".
• 🚫 Avoid areas near metal objects, microwaves, or other sources of interference.
• 🌿 If possible, place the device at a height of 1-1.5 meters from the floor.

Channel settings:

• 📶 For 2.4 GHz, choose channels 1, 6, or 11 — they don't overlap.
• 🔄 For 5 GHz, use channels 36, 40, 44 or 48 (in Russia allowed).
• 🛠️ Manually specify 20 MHz channel width for 2.4 GHz (reduces interference) and 80 MHz for 5 GHz (increases speed).

Additional functions:

• 🔄 Turn on Roaming (if supported) so that devices automatically switch between the main router and repeater.
• 📡 Disable the Guest Network on the Relayer – It Can Be Mischievous.
• 🔒 Use the same security settings (WPA2-PSK, AES) both-device.

To check the signal quality, use utilities like Wi-Fi Analyzer (Android) or NetSpot (Windows/macOS). The optimal signal level for stable operation of the repeater is not lower -60 dBm, if it's worse. -70 dBm, move the device closer to the main router.

💡

If the Xiaomi repeater overheats frequently, place it in a ventilated location or use a cooling stand.Overheating can cause spontaneous reboots and loss of communication.
