Modern Xiaomi and Redmi smartphones allow you to instantly share internet access without having to dictate complex passwords. The technology QR coding has become the standard for quick authentication on wireless networks. You don't need to manually enter characters; simply point the camera.
operating system MIUIThe platform that powers Redmi devices has built-in tools for working with graphical encryption. This makes the setup process as simple as possible for any user. In this article, we'll cover all the details, from scanning existing tags to creating your own.
This method is suitable for both connecting to a home router and for guest access in a cafe or office. Understanding how this feature works will save you time. Let's look at how to implement it in practice.
Preparing the device for code scanning
Before you begin scanning, you need to make sure your device is ready for use. On Redmi smartphones, this function is usually handled by the built-in app. ScannerIt is already pre-installed in the system and does not require installation of additional software.
Sometimes users try to find the necessary option in the Wi-Fi settings, which isn't always effective. It's much faster to launch a separate tool. It's also important to check that the wireless module itself is enabled in the notification shade.
⚠️ Important: Make sure the smartphone screen you're scanning the code from is bright enough and the camera lens is clean. Grease stains can interfere with recognition.
To get started, follow these steps:
- 📱 Unlock your Redmi's screen and find the Scanner app icon on your home screen.
- 📡 Make sure the slider is Wi-Fi in the top curtain it is activated and lights up blue.
- 🔒 If you're asked for permission to access geolocation or Bluetooth, confirm the action for it to work correctly.
The scanner interface may vary slightly between firmware versions. However, the basic functionality remains the same. The key is to get a clear image of the square cipher in the viewfinder frame.
Connection process via built-in scanner
The most common scenario is when you already have a QR code image on the screen of another device or on paper. The process in this case is extremely simple and takes just a few seconds. The system automatically recognizes the data type and suggests the appropriate action.
Point the camera at the code. Once the frame aligns with the image, it will be automatically scanned. A pop-up window will appear on the screen prompting you to connect to the network. All you have to do is confirm the action.
In some cases, if the network is password-protected, the system may request additional confirmation. This is a normal security response. AndroidAfter confirmation, the phone will automatically save the credentials and establish a connection.
Let's look at the step-by-step algorithm in more detail:
- 🎯 Open the app
Scannerand point the camera at the code. - 🔗 Wait for the notification "Wi-Fi network found" or a similar message to appear.
- ✅ Click the button "Connect" in a pop-up window.
If the code contains only the SSID (network name) without a password, the phone will simply open the authorization page or connect immediately. If the code is damaged or illegible, try adjusting the device's angle.
☑️ Check before connection
Using the camera instead of a separate app
In new versions of the shell HyperOS With the latest MIUI updates, scanning functionality is integrated directly into the Camera app. This eliminates the need to search for a separate icon. Simply launch the camera mode.
When you point the lens at a QR code, a yellow icon, shaped like a square with dots or a magnifying glass, appears in the corner of the screen. This indicates that the system has recognized the graphic pattern. Tapping this icon will begin processing the data.
This method is convenient because it doesn't require switching between apps. However, it may be slower than a dedicated scanner. Additionally, in some regions, functionality may be limited by Google Lens settings.
To activate this feature:
- 📸 Launch the default application
Cameraon your Redmi. - ⚙️ In the top menu, find the "Google Lens" icon or the scanner icon (three stripes).
- 📡 Point the lens at the code and wait for the network notification to appear.
If the camera isn't responding to codes, check your settings. The QR code scanning feature may be disabled in the camera settings menu. Also, make sure the app has permission to use the camera.
Why can't the camera see the code?
The camera may not recognize the code if the source device's screen has a protective glass with an anti-reflective coating that distorts the image. The issue also occurs if the screen brightness is low or there is strong glare from lamps. Try adjusting the angle of the phone or cleaning the lens.
Create your own QR code for guests
The opposite situation often arises: you need to host guests and want them to connect to your Wi-Fi quickly. Entering a long password every time is inconvenient. In this case, you can generate your own code to share.
On Redmi devices, this feature is built into the wireless network settings. No third-party apps are required. You can save the generated image to your gallery or send it directly to your contact via messenger.
This is especially convenient for smart home owners, where multiple devices require connection. It also eliminates the need to dictate complex symbols containing numbers and punctuation.
Instructions for creation:
- 📲 Go to
Settings → Wi-Fion your Redmi. - 🔓 Click on the name of the active network or find the "Share" option (QR code icon).
- 💾 Save the image to your gallery or take a screenshot.
⚠️ Warning: Do not share the generated QR code with the password on public sources or social media. Anyone who sees the image will be able to access your network.
Once you've generated the code, you can print it out and hang it somewhere visible, or simply share your phone screen with friends. This code won't expire until you change your router password.
Comparison of connection methods on Redmi
Users often wonder which authentication method is most effective. Each method has its advantages and disadvantages depending on the situation. Below is a table to help you choose the best option.
The method you choose depends on whether you have physical access to the router, whether you know the password, and what device you're using for scanning. Security standards also play a role.
| Method | Speed | Password required | Security |
|---|---|---|---|
| MIUI Scanner | High | Automatically | High |
| Google Camera | Average | Automatically | High |
| Manual input | Low | Yes (manually) | Average |
| NFC tag | Instant | No (automatic) | High |
As you can see from the table, using the built-in scanner MIUI is the most balanced solution. It combines speed and reliability. Manual entry remains a backup option in case of technical failures.
Troubleshooting connection issues and errors
Despite the simplicity of the technology, errors sometimes occur. The phone may display "Unable to connect" or simply ignore the code. Most often, the problem lies in frequency incompatibility or outdated encryption protocols.
Modern Redmi smartphones support standards WPA3 And WPA2If your router is configured to use legacy WEP or enterprise-specific settings, automatic connection may not work. In this case, manual configuration will be required.
It's also worth keeping in mind that some codes may lead to decoy sites. Always check the network name (SSID) before confirming the connection. If you see "Free_Internet_24" instead of the expected "Home_WiFi," it's best to refrain from proceeding.
Basic diagnostic steps:
- 🔄 Restart the Wi-Fi module by turning it off and on in the curtain.
- 📶 Make sure you are in an area with a strong signal from your router.
- 🗑️ Delete the saved network from your phone's memory (Forget network) and try again.
In rare cases, resetting network settings can help. This will return all connection settings to factory defaults but will preserve your personal data and apps.
Frequently Asked Questions (FAQ)
Is it possible to connect to Wi-Fi if there is no internet on the screen?
Yes, you don't need an internet connection to scan the QR code and connect. The code contains all the necessary information (SSID and password) in graphical form. Internet access will be available immediately after successful authorization.
Is it safe to scan codes from unknown sources?
The scanning process itself is safe. However, if the code leads to a phishing site instead of automatically connecting, there is a risk of data theft. Always verify that the pop-up window actually offers a Wi-Fi connection and not a link.
Why doesn't Redmi offer to connect after scanning?
The code may be corrupted, contain a syntax error, or the network may be too far away. Also, check if the device's network storage is full. Try deleting old profiles.
Does this method work on all Android versions?
Native QR code scanning for Wi-Fi is available in Android 10 and above. Older Redmi devices may require installing a third-party scanner app from Google Play.
