How to disconnect a device from the access point Xiaomi: step-by-step instructions for all models

Xiaomi’s access points — whether Mi Router, Redmi Router, or Redmi/POCO mobile hotspot — often become the hub of a home network, connecting dozens of gadgets at once, but over time, the list of connected devices grows, and some may require forced shutdowns, such as if you suspect a data breach, notice suspicious activity, or just want to restrict access to certain devices.

In this article, we will analyze all the current ways to disconnect devices from Xiaomi access points – from standard methods through the router’s web interface to hidden functions in the Mi WiFi mobile application. Particular attention will be paid to the nuances for different firmware (MIUI, Padavan) and models (Mi Router 4A, Redmi Router AX6, Xiaomi AIoT Router AC2350). If you need to urgently block someone else’s device or just “clean” the list of connections, you will find working solutions here.

1. Disconnect the device via the web interface of the Xiaomi router

The most reliable and versatile way is to use the router's administrator panel, which works on all models (Mi Router 3/4/4C, AX1800/AX3600, etc.), regardless of the firmware version, you only need access to the router's network and login data (admin login by default, password on the back of the device).

Instructions:

• 🌐 Open your browser on any device connected to the Xiaomi network and type in 192.168.31.1 (or miwifi.com for new models).
• 🔑 Enter your login and password. If you haven't, use the standard ones (admin/sticker).
• 📱 Go to the Devices section (or Connected Devices in English firmware) and here you will see a list of all connected gadgets from their devices. IP, MAC-addresses and connection times.
• ❌ Click on the Disable (or Block) button next to the device you want. Some firmware also allows you to lock the device permanently (Blacklist option).

If the Disable button is inactive or absent, the reasons may be as follows:

💡

If you often turn off the same devices, add them to the blacklist, which will save you time in the future.

2. Use of the Mi WiFi mobile application (official method)

Mi WiFi (formerly Mi Router) is Xiaomi’s official tool for managing routers via smartphone (AX3000, AX5, Redmi Router AC2100 And so, you can turn off the devices in two clicks, and the main advantage is that you don't have to remember. IP-router address or enter password each time.

Step-by-step:

1. Download Mi WiFi from Google Play or App Store.
2. Connect your smartphone to your Xiaomi router’s network.
3. Open the application and wait for automatic authorization (if you have not previously configured - enter the login / password from the router).
4. Go to the Devices tab (the icon with three connected gadgets).
5. Find the device you want in the list and swipe it left (on Android) or click on three dots (iOS).
6. Choose Disable or Block (in new versions of the app).

Pay attention to the nuances:

• 🔄 In some versions of the application, after disabling, the device can automatically connect again. MAC-Address (available in Additional settings) → Access control).
• 📱 If the app doesn’t see the router, make sure your smartphone is connected to its network (not to mobile data or other access point).
• 🔒 For models with Padavan firmware (for example, Mi Router) 3G Mi WiFi application may not work – use the web interface.

3. Disconnection via mobile hotspot on Xiaomi smartphones

If you're not using a router, but a hotspot on your smartphone (Redmi Note 12, POCO X5, Mi 11, etc.), the process of turning off devices is different. There's no web interface or special application, everything is managed through the MIUI settings.

How to disconnect the device from the hotspot:

1. Open the settings on the Xiaomi smartphone.
2. Go to the section Network and Internet → Access Point and modem.
3. Slip on the Wi-Fi Access Point (or Personal Access Point in newer versions of MIUI).
4. At the bottom of the screen, you'll see a list of connected devices. Click on that.
5. Choose to Disable or Lock (always Block option is available in MIUI 14+).

Important: on Xiaomi smartphones, you can not turn off the device connected to the USB-cable (modem mode) – only break the physical connection.

💡

On smartphones with MIUI 12 and older, you can set up automatic shutdown of access points after 5/10 minutes of inactivity - this will save battery power.

Limitations of the method:

• 🔋 Disabling devices does not affect traffic consumption – the access point will continue to consume it until it is manually turned off.
• 📵 The maximum number of connected devices to the hotspot Xiaomi — 10 pieces (on some models — 8). exceeding the limit automatically breaks the connection with the first connected device.
• 🔄 After rebooting the smartphone, the blacklist of connected devices is reset.

4. Blocking by MAC-Address: A reliable way to always

If you need to permanently prevent your device from connecting to your Xiaomi access point, use filtering by MAC-This method works on all routers and smartphones with hotspot function, but requires manual input of the address.

How to set up a lock:

1. Find out. MAC-Target Device Address: On Android: Settings → The phone. → General information → MAC-Wi-Fi address. On iPhone: Settings → Wi-Fi → (i) close to the network → MAC-On Windows: run the command to CMD: ipconfig /all | findstr "Physical Address"

Save the settings and restart the router.

💡

To copy quickly MAC-address from the smartphone screen, take a screenshot and recognize the text through Google Lens or Yandex.Kew – this will avoid errors when manually entering.

Advantages of the method:

• 🔒 The lock is effective even after the router restarts.
• 📱 The device will not be able to connect, even if it changes. IP-address.
• 🛡️ Suitable for protection from “free-liver neighbors” who connect to your network.

⚠️ Note: Some devices (especially smart speakers and IoT gadgets) may change MAC-In this case, the lock will be ineffective – use other methods (for example, changing the network password).

5. Network reset and extreme measures

If standard methods don’t help (e.g., the device sticks to reconnecting or the router is infected with malware), take drastic measures. They will reset all settings, but they will be guaranteed to remove unwanted connections.

Options for action:

• 🔄 Change Wi-Fi password: Go to router settings (192.168.31.1). → Change your password to a new one (we recommend using it). WPA3-Personal Save and restart the router for maximum protection. ⚠️ Warning: Once you change your password, all devices (including yours) will be disabled.
• 🧹 Reset router to factory settings: Press and hold the Reset button on the back of the router for 10-15 seconds (until the indicators blink). After reboot, reset the router via miwifi.com.

This method removes all user settings, including blacklists, QoS rules, and guest networks.

Disabling the WPS function:

The WPS vulnerability allows you to connect to the network without a password.

Router settings → Wi-Fi → Additional settings → Disable WPS

6. Features for different Xiaomi models

Not all Xiaomi routers and smartphones are managed the same way, and the key differences for popular devices are listed below.

For models with Padavan firmware (popular among enthusiasts), the device shutdown algorithm is different:

1. Go to the web interface (192.168.1.1 for Padavan).
2. Go to Network. → DHCP Server.
3. Find the device in the Active DHCP Leases list.
4. Copy it. IP-Address and use the command: arp -d [IP-address at the router terminal (Tools) → System Commands).

7 Automation: scripts and third-party utilities

For advanced users who want to automate device shutdowns, there are scripts and third-party programs that are useful if you need to regularly clean the network of unwanted connections (for example, in the office or public place).

Automation options:

• 🤖 Python script: Use the request library to send commands to the router. Example script to disable the device by MAC: import requests url = "http://192.168.31.1/cgi-bin/luci/api/xqsystem/block_mac" data = {"mac": "00:11:22:33:44:55", "time": "0"} # 0 — headers = {"Authorization": "Basic YWRtaW46YWRtaW4="} # admin:admin in base64 response = requests.post(url, data=data, headers=headers) print(response.text) Administrator rights and enabled scripts are required API-router access.
• 📊 WiFi Guard utility: The program for Windows/Linux, It scans the network and blocks unknown devices. It supports Xiaomi routers through Telnet/SSH.
• 🔄 Cron Rules on a router: On Padavan or OpenWRT firmware, you can set up automatic shutdown of devices on a schedule: 0 23 * /usr/sbin/iptables -A FORWARD -m mac --mac-source 00:11:22:33:44:55 -j DROP This command will block traffic from the specified MAC day-to-day 23:00.

⚠️ Attention: Automatic scripts can disrupt the network if they are not configured correctly. Before using, test them on one device and check the router logs (System log in the web interface).
