Xiaomi and Redmi have become standard for many homes because of their accessibility and functionality. However, when the Internet speed suddenly drops or the Mi Home app says that the network is congested, the user naturally asks: who exactly eats all traffic? Often this is because neighbors picked up a password, or a forgotten child’s device continues to download updates in the background.
Connected customer control is a basic home network management skill that not only optimizes speed, but also protects personal data from uninvited guests. Unlike older models, Xiaomi’s ecosystem offers multiple levels of access to this information, from simple notification in a smartphone to deep customization through a web interface. Understanding these tools will give you complete control over your digital strength.
In this article, we will look at all the ways you can monitor your online activity, learn how to distinguish between system processes and real gadgets, block unwanted users and customize guest access. This guide is relevant for most models, including the Xiaomi Mi Router 4A, Pro versions and the new Wi-Fi 6 standards.
Using the Mi Home app for quick monitoring
The easiest and most affordable way to check who is connected to your WiFi is the official Mi Home mobile app, which is pre-installed on many Xiaomi smartphones or easily downloaded from app stores. To get started, make sure your phone is on the same network as the router and you are logged in to the account to which the device is linked.
Once you run the app, find your router's card in your smart home device list, and click on it, you'll be taken to the main control menu, which displays your current download and distribution speed, and that's where you usually find the number of active customers at the top of the screen, and that number is updated in real time, and that's the first indicator of suspicious activity.
For more information, you need to go to the device management section, and not only are names displayed here, but you also have the device management section. MAC-Addresses and connection type (2.4 GHz or 5 GHz) If you see a device named "Unknown" or "Android-xyz," don't panic - it could be your refrigerator, robot vacuum cleaner or Android console. TV.
You should pay special attention to Download or Traffic, if it's available in your firmware version, which lets you see which device is consuming the most megabytes right now, and it helps you quickly identify heavyweights like torrents or 4K streaming services.
Setup and analysis through the router’s web interface
The mobile app is convenient, but for deep analysis, it is better to use the router’s full web interface. It provides access to hidden settings and more detailed logs, which are often not available in a simplified mobile interface. To get there, open any browser on your computer or phone and type in the address bar. IP-lock-house.
The standard address for Xiaomi routers is 192.168.31.1 or the domain miwifi.com. Once you enter the address, the system will request an administrator password. By default, it often matches the password from WiFi, unless you changed it when you first set it up. Beware: entering the wrong password several times can temporarily block access to the control panel.
Once you have successfully logged in, go to Settings or Connected Devices, depending on the firmware version (Chinese or global), the interface may differ, but the logic remains the same, and you'll see a table with a list of all active connections, all of them. IP-addresses and time of lease.
☑️ Network security check
The web interface also allows you to see your connection history, which is useful for identifying devices that were online before, but now offline, which helps you understand which gadgets have ever connected to your access point, and if you find an unknown device in history, that's an excuse to immediately change the security key of the network.
Extended features in the Mi WiFi app
For users who lack the standard Mi Home, Xiaomi has developed a dedicated Mi WiFi app (sometimes called Router) that is geared specifically to networking and offers more flexible management tools, which can be downloaded from official stores, although in some regions it may not be available without changing the region of the account.
The main advantage of this app is that you can manage your guest network and prioritize traffic, so you can create a separate SSID for guests that is isolated from your main network with personal files and printers, ideal when you have friends coming to your house or renting out your apartment for rent.
In the Tools or Plugins section, you often see network scanning for vulnerabilities, and the app can check if ports are open, if WPA2/WPA3 is a reliable encryption protocol, and if there are devices with outdated software, which turns the smartphone into a full-fledged pocket network analyzer.
Why are some devices displayed as “Offline”?
Mi WiFi also has a feature called “Game Acceleration” or “Device Priority” that you can manually select, for example, a console or laptop, and the router will prioritize data packets for this particular gadget, minimizing ping and delays at the expense of other background downloads.
Identification of devices by MAC-address
Often, you'll see names on the list of connected customers like espressif, honhai, or just a set of numbers. MAC-The first six characters of the address are the addresses of the network interfaces, which may not be obvious to the average user (OUI), Which point to the chip manufacturer.
For example, if you see a device with a beginning MAC-address 04:CF:8C, This indicates to the Xiaomi manufacturer, which could be your phone or light bulb. D8:9E:F3, It is often used by Ubiquiti devices and 00:1A:79 — This is Apple. Knowing these prefixes helps you weed out your devices quickly from others.
For convenience, you can make a map of known devices in your network that will make future monitoring easier and allow you to immediately notice anomalies. Below is a table with examples of common prefixes and their likely purpose in the house.
| MAC prefix (OUI) | Manufacturer | Probable device | Type of connection |
|---|---|---|---|
| 04:CF:8C | Xiaomi | Smartphone, TV box, Lamp | WiFi / Bluetooth |
| 3C:BD:D8 | Intel | Laptop, PC | WiFi / Ethernet |
| F4:F5:D8 | Chromecast, Android TV | WiFi | |
| 00:1B:63 | LG Electronics | Smart TV, Refrigerator | WiFi |
Using this systematization allows you to instantly react to new lines in your customer list. If you see a device from a manufacturer you don’t have in your home (like an HP printer when you only have a Canon), this is a sure sign of an intrusion.
Blocking Unwanted Customers and Protecting the Network
Finding an alien is only half the solution, and the main goal is to immediately restrict access to it. In the interface of Xiaomi routers, this is done through the Blacklist function or lock on the Internet. MAC-You just click on the device name and select the appropriate menu item.
Once locked, the device will not be able to connect to the network even if it knows the correct password, but it is worth remembering that an experienced user can clone the MAC address of his device to the one that is allowed (MAC-spoofing), so locking alone is not enough – you need to change the password from the WiFi network to a more complex one.
💡
Use a password generator to create a key at least 12 characters long, including numbers, capital and lowercase letters, as well as special characters.
It is also recommended to disable the WPS (Wi-Fi Protected Setup) feature, which allows you to connect to the network at the touch of a button or by pin code, but it has known vulnerabilities that allow attackers to pick up a password brute force in a matter of hours. In modern Xiaomi routers, this feature is often disabled by default, but it is worth checking.
For maximum protection, set up a Hidden SSID, in which case the router will not broadcast its name, and you can only connect to it manually by entering the network name and password on each device, which creates an additional barrier for random “neighborhood” connections.
Diagnosing problems with speed and stability
Sometimes slow internet speeds aren’t related to WiFi theft, but are due to technical issues with the router itself or interference on the air. If the list of customers is clean but the internet is not working well, check the downloads. Xiaomi routers are able to automatically choose the least loaded channel, but manual selection can give the best result.
Use built-in diagnostic tools or third-party WiFi app on your smartphone to show signal strength and the presence of nearby networks that can jam your signal, especially in the 2.4 GHz range in apartment buildings.
💡
Overheating of the router is a common cause of speed drops. Make sure that the device is in a ventilated place, not in the sun or behind the TV.
It's also worth checking if the speed limit (QoS) feature is enabled for any device. Sometimes users accidentally set download limits for a TV or set-top box, and then can't figure out why the video is slowing down. Resetting QoS settings to factory values often solves the problem.
Remember to update your router’s firmware regularly. Xiaomi engineers are constantly releasing patches that improve the stability of the wireless module and close security holes. Update checks can be set up automatically via the web interface.
