Modern Xiaomi smartphones, working on the basis of shells MIUI or the new HyperOS, which offers users advanced tools to manage wireless connections, one of the most convenient and quickest ways to log in is to use the Internet. QR-This technology allows you to instantly transfer encrypted data about the network, eliminating the need to manually enter a complex password, especially if it contains many characters.
You don't need to be a networking expert to take advantage of this feature. Android, integrated into Redmi and POCO devices, has a built-in scanner that activates automatically when the camera hovers over an image. This greatly speeds up the process of connecting guests or new devices in your home or office, making interaction with Wi-Fi technology as seamless as possible.
However, despite the simplicity, users often face nuances: codes are not read, passwords are not saved or the menu is hidden in the depth of settings. QR-In the Chinese brand, we will look at the ways of generating code for distribution and scanning methods for login. You will learn how to bypass typical errors and provide a stable connection for all your gadgets.
Benefits of using QR-codes for WiFi on Xiaomi
Using graphical codes to communicate network settings has become the de facto standard in the Android ecosystem, and Xiaomi devices are no exception. The main advantage is speed and security. You don't have to dictate a password to guests at the risk of mischaracterizing, or write it on a piece of paper. One camera hover is enough, and the WPA2 or WPA3 security protocol will be activated automatically.
It also minimizes human error, and manual input often causes errors in the letter register or confuses similar characters such as zero and the letter "O". QR-The code eliminates this possibility, as the data is digitally transmitted directly to the smartphone’s communication module, which is especially true for networks with long and complex passwords that are difficult to remember.
Another important aspect is versatility: The code generated on your Xiaomi can be read by any modern device, whether it is an iPhone, Samsung or other Android smartphone, making it ideal for public places, cafes or offices where many different customers need quick access to the Internet without further questions to the administrator.
How to create QR-WiFi code for distribution on Xiaomi
If you own a router or just the first to connect to your Xiaomi network, you can easily create a graphical key for others. You don't need to install third-party apps, because the functionality is built into the system settings. You first need to go to the Settings → WiFi menu and make sure that the wireless module is activated.
Find the network you are already connected to (it will be marked as “Connected”) and click on the arrow to the right of the name or on the gear icon, depending on the version. MIUI. In the window of network details you will see the image QR-And underneath it is usually a share button or a scan icon, but the code is already generated by the system and ready to use.
Importantly, some firmware versions may require a screenshot to save the code as an image, while simultaneously pressing the Loudness Down and Power buttons, and then send the resulting image via instant messengers, print or show guests directly from the smartphone screen.
☑️ Checking before creating the code
⚠️ Attention: Generated QR-The code contains the password from your network in plain form (albeit encrypted in the graphics), anyone who scans it will have full access to your Internet. Don't put it in public unless you want neighbors to use your traffic.
Instructions for scanning code through the camera and Mi Scan
Connection process through the network QR-The code on Xiaomi devices is simplified and often does not require even opening special applications.The standard camera of the smartphone is equipped with an intelligent recognition module that is activated automatically. Hover the camera lens over the code, and after a second on the screen will appear a pop-up notification with a suggestion to connect to the network.
If automatic recognition doesn't work, you may have Google Lens or Mi Scan disabled in your camera settings, so open the Camera app, find the Scanner or Mi Scan option in the top menu or "More" mode. Switch to this mode, frame the image, and the system reads the data.
After a successful read, a window will appear on the screen with the network name and the Connect button. When you click on it, the smartphone automatically enters the password and initiates the connection. You will only have to wait for the WiFi icon to appear in the status bar. The whole process takes seconds and does not require any input.
What if the camera doesn’t see the code?
Configure via WiFi menu and system scanner
In some cases, using the main camera can be uncomfortable, for example, if you want to connect to a network whose code is on the screen of your computer or another phone and you need to switch windows. In this situation, you better use the built-in scanner in the WiFi settings menu. Go to Settings → WiFi and click on the scanner icon, which is usually located in the upper right corner or next to the network search field.
This tool specializes in network connections, not only reads code, but also immediately suggests adding the network to the list of saved ones. Unlike a general camera, this scanner is less sensitive to ambient light and responds more quickly to network SSIDs. This is the preferred method for system administrators or those who often configure new devices.
After scanning through the WiFi menu, the system can request confirmation of the action, a security measure to prevent accidental connection to malicious access points with similar names. IP-address and access the global network.
💡
If you often give out WiFi to guests, add a widget with a WiFi. QR-To do this, press the empty space on the desktop, select "Widgets" → "Scanner or WiFi, and fast access will always be at hand.
Problem Solving: Code is not read or connected
Despite the system’s debugging, Xiaomi users sometimes face situations where QR-The most common cause is poor image quality or poor lighting, make sure the code is clear, not blurred and light is emitted, and it can also be caused by contamination of the camera lens, which often happens in everyday use.
Another common error is the encoding format: Xiaomi’s standard scanners are great at reading code generated using WPA/WPA2. However, if the network uses specific enterprise security settings or a hidden SSID, the automatic connection may not work, in which case the system will prompt you to enter the data manually.
It's also worth checking if your smartphone is running on flight mode or blocking the firewall connection. Sometimes it helps to reboot the WiFi module: turn it off and turn it on in the notification curtain. If the problem persists, try "Forget the Network" in the settings and repeat the scan again.
| Problem. | Possible cause | Decision |
|---|---|---|
| Camera's not responding. | Contaminated lens or little light | Clean the camera, improve the lighting |
| Connection error | Wrong password in the code | Check the relevance of the password at the admin |
| No network found. | Hidden SSID or Long-Distance Router | Get closer or add a network manually |
| Only 2.4 GHz | The router does not support 5GHz in this mode. | Separate network names in router settings |
⚠️ Note: If you scan your code with a smartphone suggesting you click on a strange link or download an app instead of connecting to WiFi, immediately discard this action. This WiFi code contains only authorization data, not executable files.
Frequent Questions and Technical Nuances (FAQ)
To conclude, we’ll touch on a few technical issues that often raise questions from Xiaomi, Redmi and POCO owners, and understanding these details will help avoid confusion and effectively leverage the capabilities of your HyperOS or MIUI operating system.
One of the key issues concerns frequency compatibility. Modern routers often operate in two bands: 2.4 GHz and 5 GHz. QR-If your smartphone supports 5 GHz, but the code leads to 2.4 GHz, the speed may be lower than expected. In such cases, it is better to create separate codes for each range if the router translates them as different networks.
It is also important to keep in mind the security of personal data. QR-The code, you're actually transferring the keys to your local network. The attacker who gained access could theoretically try to attack other devices on the network. So use the guest network to generate public codes if that feature is available on your router.
💡
Using a guest network to generate public QR-Codes are the best security practice to isolate your personal devices from outsiders.
