In today’s digital home, Xiaomi’s network often becomes a central node connecting dozens of gadgets, from smart light bulbs to TVs and smartphones. However, there are times when a network administrator needs to forcefully break a connection with a particular customer. This may be necessary to save traffic, improve security or eliminate interference with mission-critical devices. Understanding how to disconnect devices from Xiaomi’s WiFi is a basic skill for any owner of the brand ecosystem.
The procedure for disconnecting can be very different depending on whether you use your smartphone as an access point or manage your home network through a dedicated router. The first is a time limit, and the second is a deep network policy setting. The wrong actions can lead to you losing access to your own router or disrupting your smart home.
In this article, we will take a look at all the available connectivity management methods, look at the standard Android operating system with a MIUI or HyperOS shell, and focus on Mi WiFi software and the router web interface, and learn not only to block uninvited guests, but also to create flexible access rules for different family members.
Using Mi WiFi Application to Control Access
The most convenient and functional way to manage the network is to use the official Mi WiFi application. This tool allows you to see a list of all connected customers in real time and manage them remotely. To start work, you need to log in to the application using an account associated with your router. The program interface is intuitive and provides instant access to traffic statistics.
To turn off a particular device, go to Customers or Devices, which displays the complete list of gadgets on the network. Select the desired object from the list. The control menu that opens usually has a "Disable" button or lock slider. Instant system action causes the connection to break, and the device will no longer be able to transmit data until the restrictions are removed.
⚠️ Attention: After forced disconnection through the application MAC-The device address can be automatically blacklisted, meaning that the gadget won’t be able to connect again even if you reboot the router.
The app also allows you to set speed limits for individual users, a useful alternative to locking them down completely if you don't want to completely deny someone access but want to limit your resource consumption, such as lowering the priority for your TV while you're on your computer.
Blocking through the web interface of the Xiaomi router
To fine-tune network settings, experienced users often access the router's web interface through a browser by entering it. IP-The gateway address, which is often the default 192.168.31.1 or miwifi.com, gives access to advanced settings not available in the mobile application, including detailed logs and firewall settings.
Once you have entered your administrator credentials, go to the WiFi settings or Security Center section, and this is where you find the Device Management or Blacklist tab, and unlike the mobile app, the web interface allows you to edit access lists in more detail. You can manually add. MAC-Addresses to a list of prohibited or permitted devices, creating a whitenet.
- 🔒 Select the option “Blacklist Mode” to block specific violators.
- ✅ Use the “White List Mode” to only allow access to trusted gadgets.
- 📡 Check the logs of connections to identify suspicious activity.
Save the configuration before leaving the menu so that your settings do not disappear after a power surge.
☑️ Network security check
Disconnecting customers through smartphone settings (Access Point)
If your Xiaomi or Redmi smartphone is giving away the internet, the management of your connected customers is done through standard Android settings, which is relevant when you are away from home and want to restrict access to your mobile traffic.
Go to the settings menu, select "Wi-Fi hotspot" and click on the list of connected devices, IP-Address and volume of traffic consumed. To turn off, just click on the device name and select "Disable" or "Block" and then the connection will be severed, and reconnection without your knowledge will become impossible.
Some versions of the HyperOS shell offer an automatic lock-out feature for unfamiliar devices, which, if enabled, will request confirmation when you try to connect a new gadget, a reliable way to protect yourself from “neighborhood” traffic in public places.
⚠️ Note: When you turn off a device through an access point on a smartphone, it may automatically try to reconnect after a few seconds unless you blacklist it explicitly.
Why is the device reconnecting?
Setting up white and black lists (MAC-filtering)
The most reliable method of access control is MAC-Filtering: Each network adapter has a unique physical address that cannot be changed by software on most consumer devices, and filtering settings allow you to create strict rules: let only your own guests or keep specific guests away».
To set up a white list, you must first collect MAC-The router then activates the White List mode and enters the addresses, and all other connection attempts will be rejected by the router at the protocol level, even if the attacker knows the WiFi password.
The Black List works the opposite way: you put unwanted customers in the list, and it's a convenient way to turn off one or two devices without reconfiguring the access for everyone else. MAC-The address of the adapter (cloning), it will be able to bypass the lock.
| Type of filtration | Principle of action | Level of security | Difficulty setting up |
|---|---|---|---|
| Black List | Blocking specific addresses | Low. | Low. |
| White List | Allow only trusted addresses | High-pitched | Medium |
| Guest network | Isolation of guests from the main network | Medium. | Low. |
| Change of password | Breaking all connections | High-pitched | Low. |
When using the whitelist, be careful: if you lose access to the router or forget to deposit your device, you can only restore control through a full reset to the factory settings.
💡
The White List is the only way to guarantee that you will not be allowed access to anyone, even if they recognize your WiFi password.
Guest network for temporary access
Rather than permanently disconnecting guests’ devices from the main network, it’s smarter to use Guest Network, a feature built into all modern Xiaomi routers, which creates a separate hotspot with its own name and password that is isolated from your personal LAN.
Guests who connect to guest WiFi only access the Internet. They don't see your printers, NAS-It solves two problems at once: data security and not having to reset the password of the main network after the guests leave.
- 🛡️ Traffic isolation protects your personal files from the eyes of others.
- ⏱️ You can set a timer for guest access.
- 🚫 It is easy to turn off the entire guest network with a single button.
You can set up a guest network in both the Mi WiFi app and the web interface, and it's recommended that you let guests access through that channel, and if guests are gone and traffic is being consumed, you just turn off the guest SSID without affecting your smart devices.
💡
Use different passwords for the main and guest network, and you can write the guest password on a sticker and keep it in the hallway so you don't dictate it every time.
Radical measures: password reset and reset
If you suspect that an attacker who uses sophisticated methods to bypass locks has connected to your network, the most effective way is to completely change the WiFi security key. Once the password is changed in the router settings, all devices will be immediately disabled.
To reconnect, each gadget will need to enter a new password, ensuring that no stored device can log in without your knowledge, a technique that is particularly effective against standard WiFi hacking software, which often uses outdated password databases.
As a temporary measure, you can use a router reboot. Some simple devices may not have automatic reconnection and will remain “overboard” until manual intervention by the user, but for regular customers this is only a short-term inconvenience.
