Owners of Xiaomi smart devices often encounter an intrusive visual element that appears on the screen or in the app immediately after a connection is established. This is a QR code prompting guests to connect to your network without entering a password. While this feature is convenient for quick access sharing, the constant backlight or pop-up window can be annoying, especially if you use the device as a media center or monitor.
The deactivation process depends on the type of your equipment: whether it is smart router, a TV set-top box, or a modern TV running the MIUI TV interface. In most cases, the default interface settings don't provide a direct "Uninstall" button, requiring a deeper dive into system settings or the use of third-party utilities.
In this article, we'll explore all known solutions. We'll cover how to change system behavior through the engineering menu, local storage settings, and specific Mi Home app settings. It's important to understand that interfaces may vary depending on the firmware version.
The origins of the QR code in the Xiaomi ecosystem
The QR code generation feature for guest networks was implemented by developers to simplify users' lives. Instead of typing a complex password of numbers and symbols, guests simply scan the image with their smartphone camera. However, on Xiaomi devices, this feature often works aggressively, taking up a significant portion of the screen or appearing at inopportune moments.
Technically, this is implemented through the service MIUI Share or a built-in guest access module in routers of the series Axia And ProThe system automatically detects that the network is active and offers to visualize the entry point. The problem is compounded by the fact that in many regions, global firmware versions differ from Chinese versions, where settings may be more flexible.
It's worth noting that the persistent display of the code may indicate that the "Guest Network" mode with priority display is enabled. If you don't actively use this feature, it's best to disable it to free up interface resources and improve the visual experience.
⚠️ Note: MIUI TV interfaces and router firmware are updated regularly. The menu item layout may differ slightly from that described in the instructions. If you don't find the exact name, look for similar options in the "Network" or "Security" sections.
Disabling QR codes on Mi Box TVs and set-top boxes
The question "how to remove the Xiaomi WiFi QR code" is a common one among TV owners. After successfully connecting to the network, a static image or pop-up notification may remain on the screen. To remove it, you need to change the network display settings.
The first step is to check the guest network status. Go to Settings → Network & Internet → Wi-FiIf "Guest Network" or "Show QR Code" is enabled, simply toggle the switch to "Off." In some MIUI TV versions, this option is hidden in the "Advanced" submenu.
If there is no standard switch, try the following method:
- 📱 Open the app Mi Home on a smartphone linked to a TV.
- 📡 Select your device from the list of available devices.
- ⚙️ Go to your device settings (three dots in the corner).
- 🚫 Find the "Display network status" option and disable it.
In cases where software disabling is impossible due to firmware bugs, users resort to hiding the element by changing the interface theme. Installing a minimalist theme can obscure the QR code layer, making it invisible, although the background process may still technically run.
Setting up Xiaomi and Redmi routers: hiding guest access
Router owners Xiaomi Router AX3600, AX9000 or older models of the series Pro You may notice code generation in the web interface or application. This is often due to an active guest profile. To remove the code, you need to completely revise your guest access policy.
Go to the router's web interface at 192.168.31.1 or via the app Mi WiFi. Go to the section Wi-Fi Settings → Guest NetworkHere, it's important not to simply turn off the network, but to find the "Visibility" or "Show QR code on home screen" setting. Make sure the "On" status is changed to "Off."
For advanced users with access to the router's SSH console, it's possible to forcefully disable the generation service via the command line. This requires caution:
cd /etc/init.d/etc/init.d/guest_wifi stop
chkconfig guest_wifi off
After executing the commands, you must reboot the device. This will disable the daemon responsible for creating the visual representation of the guest network, ensuring that the code is removed from the administration interface.
☑️ Checking router settings
Working with the Mi Home app: system limitations
Application Mi Home It's the central control hub and often triggers QR codes to appear on connected devices. In the latest versions of the app, the developers have added a "Smart Home" feature that automatically offers to share access.
To restrict this behavior, open the user profile in the app (the "My" tab). Find the section Settings → General → Share AccessHere you can disable automatic code generation for new devices. It's also worth checking the settings for a specific room: sometimes the code is tied to a location.
There's a caveat with caching. Even after disabling the feature, the old QR code may remain in the device's memory. In this case, clearing the app's data will help:
- 🗑️ Go to your Android (or iOS) phone's settings.
- 📲 Find the app Mi Home in the list of installed programs.
- 💾 Select "Storage" and click "Clear cache" (not data, to avoid resetting your devices).
- 🔄 Restart the application and check the result.
Risks of data cleansing
If you select "Clear data" instead of "Clear cache," you'll have to re-login to your Xiaomi account and re-link all devices. Only do this if other methods fail.
Comparison of shutdown methods for different devices
The effectiveness of these methods may vary depending on the specific device model and software version. Below is a table to help you choose the best solution for your specific situation.
| Device | Disconnection method | Complexity | Efficiency |
|---|---|---|---|
| TV Mi Box S | Disabling the guest network in the settings | Low | High |
| AX3600 router | Web interface settings | Low | Average |
| Xiaomi smartphone | Changing the design theme | Average | Visual |
| Router (SSH access) | Disabling the daemon via console | High | 100% |
| Mi Home app | Clearing cache and profile settings | Low | Temporary |
As the table shows, the most reliable method for routers is via the console, but this requires technical skills. For regular TV users, the standard interface settings are sufficient.
Common mistakes and additional recommendations
When attempting to remove a QR code, users often make the mistake of completely disabling the Wi-Fi module, which deprives the device of its smart functions. It is important to distinguish Disabling the radio module and disabling the visual element. Your goal is to hide the image while maintaining functionality.
Another common issue is a factory reset. This is a drastic measure that doesn't always help, as the system will prompt you to create a QR code again during the initial setup. It's best to avoid a full reset unless there are no other options.
Use the following tips to optimize:
- 🛡️ Update your device's firmware regularly, as new versions of MIUI often patch intrusive elements.
- 👁️ Check if "Demo" mode is enabled in the display settings, which can force the display of codes.
- 🔌 When setting up your router, immediately disable all unnecessary printing and sharing services if they are not in use.
Security and privacy when using QR codes
While we're discussing how to remove the code, it's worth mentioning security. The WiFi QR code contains an encrypted password. If someone else takes a picture of your screen, they'll gain access to the network. Therefore, if you can't remove the code programmatically, consider physically protecting your screen or changing the password to a more complex one that isn't transmitted via the standard WPA2 protocol in the code.
Displaying such codes on Xiaomi devices in corporate networks or offices is strictly discouraged. This creates a security breach. In such cases, the only right decision is to create a separate guest VLAN network, isolated from the main infrastructure, and disable any visual cues on the access point.
⚠️ Warning: Modifying system files or using SSH commands on your router may void your warranty. Only attempt such actions if you are confident in your skills and understand the risks.
FAQ: Frequently Asked Questions
Is it possible to permanently remove a QR code without re-flashing the firmware?
Yes, in most cases, disabling the guest network feature in your router or TV settings is sufficient. A full firmware update is rarely required, unless it's a bug in a specific software version.
Why does the code appear again after turning it off?
This could be due to caching in the Mi Home app or an automatic configuration update from Xiaomi servers. Try disconnecting the internet connection on your device, removing the code, and only then reconnecting.
Does removing the code affect Wi-Fi speed?
No, the QR code itself is just a graphic element. However, if it's part of an active guest access service, disabling it may slightly reduce the load on the router's processor, but it won't affect data transfer speed.
What should I do if there is no disable option in the menu?
Try changing the region in your phone settings (for example, to India or Europe) and reconfiguring the device. MIUI interfaces may have different features in different regions.
