Xiaomi And RedmiYou'll learn where to find ready-made code for your network, how to generate a new one, and what hidden scanner features can be useful in various situations. We'll also cover security issues and compatibility with other operating systems.
Benefits of using QR codes for network access
Using Quick Response (QR) technology to transfer network settings has become a de facto standard in the mobile device ecosystem. The main advantage is speed: the process takes literally a couple of seconds, which is especially important when hosting a large number of guests or in office settings where multiple employees have access.
Furthermore, this method significantly reduces the risk of typing errors. Wi-Fi passwords often contain complex combinations of letters, numbers, and special characters that are easily confused on a touchscreen. QR code eliminates the human factor by transmitting the exact connection string directly to the phone's network module.
⚠️ Warning: When using QR codes, remember that anyone with access to the code image can connect to your network. Do not post screenshots of access codes to public sources or social media without first securing them.
Another important aspect is versatility. Built-in scanners in the shell MIUI and a standard camera Android They recognize codes instantly, without the need to install third-party apps. This makes the technology accessible to users of any technical skill level.
- 🚀 Instant connection without manually entering long passwords.
- 🔒 Reduced probability of error when transmitting complex symbols.
- 📱 Possibility of connecting devices without a full keyboard (cameras, printers).
- 👥 Easily provide guest access without disclosing the main password.
How to find your network's QR code in Xiaomi settings
If your smartphone is already connected to a wireless network, the system automatically generates a unique access code that can be used to connect other devices. You can find it in the standard settings menu, but the path may vary slightly depending on the firmware version.
First, you need to go to the section Settings and select the item Wi-FiA list of available networks will be displayed, with the currently active connection indicated by a corresponding indicator. Click on your network's name or the arrow to the right of it to expand its options.
In the menu that opens, you will see a button Share or an icon resembling a QR code. Tapping it will require identity verification via a fingerprint scanner, pattern lock, or Face ID. This is a security measure that prevents unauthorized access to network data.
☑️ Check before creating code
After successful authentication, an image containing encrypted network data will appear on the screen. This is the code that the other device needs to scan. It's important to note that on some versions HyperOS The interface may be slightly modified, but the logic remains the same: active network settings → button/QR.
What to do if the button does not appear?
If the "Share" button or QR code doesn't appear, try refreshing the Wi-Fi settings page or restarting your smartphone. In rare cases, on older versions of Android, this feature may be hidden by the manufacturer, requiring a third-party app.
Step-by-step instructions for scanning the code
The process of reading the code on devices Xiaomi It's as simplified as possible and integrated into system apps. You don't need to search for a special app in the app store, as the necessary functionality is already built into the camera or control center.
There are several ways to activate the scanner. The fastest is to open the default app. Camera and point the lens at the code. If Google Lens or the built-in scanner is active, the system will automatically recognize the code and prompt you to connect to the network.
An alternative option is to use a dedicated app. Scanner (or Scanner), which is often preinstalled in the "Tools" folder. Launch it, point it at the image, and the phone will automatically prompt you to connect to Wi-Fi.
⚠️ Important: Make sure the source device's screen is set to maximum brightness and the receiving device's camera lens is clean. Glare and dirt can make it difficult to read the code matrix.
You can also use the Control Center. Swipe down from the top corner of the screen to open the notification shade and find the scanner icon. This method is useful if the camera app doesn't immediately read the code for some reason.
- 📸 Open the Camera or Scanner app.
- 🎯 Point the lens so that the code is in the frame.
- 📲 Wait for the vibration or confirmation sound.
- ✅ Click on the "Connect to network" pop-up notification.
After pressing the confirmation button, your phone will automatically enter all the necessary parameters and establish a connection. The connection status will be displayed in the status bar, and a checkmark or activity icon will appear next to the network name.
Generating a QR code for a guest network or new router
You often need to connect a device that doesn't yet have a password, or you want to create a permanent access pass for guests. In this case, it's helpful to know how to generate a code in advance or print it out.
To generate a code, you can use not only your phone's settings, but also third-party generators if the built-in functions are unavailable for some reason. However, the standard method Settings → Wi-Fi → Share is the most secure, since data is not transmitted through third-party servers.
If you are setting up a new router, many modern models Xiaomi Router and other brands have a factory-installed QR code on a sticker on the case. It contains initial setup information. Simply scan it with the camera, and the phone will prompt you to launch the setup app or connect immediately.
| Parameter | Description | Where to find |
|---|---|---|
| SSID | Wireless network name | Wi-Fi settings |
| Encryption type | Security protocol (WPA2/WPA3) | Network properties |
| Password | Network access key | Hidden in settings, visible in QR |
| Hidden network | No name broadcast mode | Additional router settings |
When creating guest code, it's recommended to use your router's guest mode, if supported. This will create an isolated network that won't allow access to your personal files and devices on the local network, providing an additional layer of privacy. security.
Troubleshooting and fixing connection errors
Despite the simplicity of the technology, users sometimes encounter connection issues. The most common cause is frequency band incompatibility. If the router only broadcasts 5 GHz and the phone only supports 2.4 GHz (or vice versa), the connection may fail, even if the code is read correctly.
Another common issue is that temporary networks have expired or the administrator has changed the password. In this case, the old QR code will become invalid, and the system will return the error "Unable to connect." There's only one solution: request a current code from the network owner.
It's also worth paying attention to the region. Some models Xiaomi, intended for the Chinese market (CN Version), may have restrictions on the use of certain Wi-Fi channels used in other countries. This may result in an unstable connection.
⚠️ Note: MIUI and HyperOS interfaces are subject to update. Button and menu layouts may change. If you can't find the item described, search your phone's settings by entering "Wi-Fi" or "QR code."
If the camera doesn't focus on the code, try adjusting the distance to the object or cleaning the lens. In low-light conditions, turn on the flash if the scanner app allows it. Matrix codes require good contrast to be read.
- 🔄 Restart the Wi-Fi module (turn it on/off in the settings).
- 🗑️ Delete the saved network and try connecting again.
- 📶 Check if the MAC address filter is enabled on your router.
- 📲 Make sure your phone has the latest system updates.
