Smartphone owners Xiaomi, Redmi And Poco Often faced with the need to quickly connect to a wireless network. Instead of manually entering a complex password consisting of many characters, it is much more convenient to use technology QR codesThis feature is built into the shell. MIUI and allows you to instantly transfer network data to another device or save it for yourself.
Scanning Wi-Fi code There are several ways to log in on Redmi, each with its own unique features. You can use the standard camera, the built-in scanner in the settings, or third-party apps. Understanding these methods will help you save time and avoid data entry errors.
In this article, we'll detail all available options, explain how to create your own guest code, and answer frequently asked questions. We'll also discuss potential recognition issues and how to resolve them. It is important to know that you do not need an internet connection to scan the access code, as all the information is already encrypted in the image.
Using a standard camera for scanning
The most obvious and quick way to scan a Wi-Fi code on a Redmi Note 5 is to use the built-in Camera app. In the latest versions of the shell, MIUI Image recognition algorithms have been significantly improved. You don't need to look for a separate app or delve into deep menu settings.
Just open the app Camera and point the lens at an image with a QR code. The system will automatically recognize the code type and suggest the appropriate action. If the code contains network connection information, a pop-up notification will appear on the screen.
Tap the notification, and your phone will automatically open the Wi-Fi settings menu. The device will automatically enter the network name (SSID) and password, then connect. This method is ideal for quickly connecting at a cafe or a friend's house.
However, sometimes automatic recognition may fail if the code is corrupted or has a non-standard format. In such cases, the system may simply open the link in the browser or do nothing. In these cases, it's worth turning to alternative methods built into the system.
Scan codes via Wi-Fi settings
If for some reason the camera can't detect the code, you can use the built-in scanner in the wireless network menu. This method is more reliable, as it specializes in network connections. It ignores other types of codes, focusing on network parameters.
To do this, go to Settings and select a section Wi-FiAt the top of the screen, next to the network search field, you'll find a scanner icon (usually a square with lines or a camera). Tapping it activates scanning mode.
Point the camera at the code. Once successfully scanned, your phone will immediately prompt you to connect to the network. This method is especially useful if you have disabled the "smart scan" feature in the main camera or if you are using the simplified system interface.
Using the settings menu ensures you don't end up on a malicious website, as the system checks the code content for network parameters. This is an important aspect. digital security, which is often forgotten.
Generate a QR code to distribute a password
Not only scanning but also generating a code for guests is an important feature. If friends are over, you no longer have to dictate your password or display it on the screen, risking others seeing it. You can generate a unique code right on your smartphone.
Go to settings Wi-Fi and tap the name of the network you're already connected to. A card with connection information will open on the screen. There you'll see a large QR code. Any guest can scan it and connect instantly.
This code contains the encrypted password and encryption type. Even if the guest has a phone of a different brand (for example, iPhone or Samsung), it will still be able to connect, since the code format is a universal standard.
☑️ Preparing to receive guests
It's worth noting that the code is dynamically updated in some firmware versions to enhance security. Therefore, taking a screenshot and sending it to friends in advance may not be the best idea if the system requires up-to-date generation.
Using the Mi Scan app and Google Lens
In the ecosystem Xiaomi often the app is pre-installed Mi Scan (or simply "Scanner"). It's part of the system tools and offers advanced functionality. In addition to Wi-Fi, it can recognize products, documents, and text.
To scan, open the app ScannerSelect "Wi-Fi" or "Code" mode. Point the camera at the image. The app will not only connect you to the network but also save a history of scanned codes, making it convenient for future use.
An alternative could be Google Lens (Google Lens), which is built into many Android smartphones. It's accessible via the search widget or by long-pressing an image in the gallery. It's a powerful tool that understands the context of an image.
| Method | Speed of work | Accuracy | Additional functions |
|---|---|---|---|
| Camera | High | Average | Basic recognition |
| Wi-Fi settings | High | High | Networks only |
| Mi Scan | Average | High | History, products |
| Google Lens | Average | Very high | Translation, text |
The choice of tool depends on your personal preferences and the specific situation. If you just need a quick connection, a camera will suffice. If you administer a network and need to analyze codes, a specialized scanner is a better choice.
Troubleshooting code recognition issues
Sometimes users experience problems with their Redmi device not recognizing the code or displaying an error when attempting to connect. This can be caused by various factors, from a dirty lens to software glitches in the device's interface. MIUI.
A common cause is the low resolution of the screen displaying the code or poor lighting. Issues can also arise if the code is on a glossy surface, creating glare. In such cases, try adjusting the angle of your phone.
⚠️ Attention: If your phone prompts you to download an app to open a QR code, be careful. Redmi's native features don't require any additional software to connect to Wi-Fi. This could be a phishing attempt.
If the issue is software related, try clearing the cache of the Camera or Scanner app. To do this, go to Settings → Apps → All apps, find the one you need and select Clear data.
What to do if the code is corrupted?
If the physical code is damaged (torn, painted over), scanning may be impossible. In this case, try finding a digital version or ask the network owner to show you a copy of the code from their phone where it's clearly visible.
It's also worth checking whether your antivirus or system security software is blocking camera access for certain apps. In rare cases, restarting your smartphone can help, as it clears temporary communication module errors.
Security when using QR codes
While the technology is convenient, it carries certain risks. A QR code is simply encrypted text, and attackers can replace a legitimate code with their own. Instead of connecting to free Wi-Fi at a cafe, you might end up on a phishing website.
Always check the notification that appears after scanning. If it shows a website address instead of a network name, do not click the link under any circumstances. The real Wi-Fi code only contains connection parameters (SSID, password, encryption type).
Also, don't post your home network codes in public places without the password. Anyone can connect to your internet, which could lead to data theft or illegal use of your connection.
⚠️ Attention: The MIUI interface and layout may vary depending on the firmware version (Global, China, Russia) and device model. If you can't find the option, use the search in the settings.
Use a guest network for visitors. Modern routers allow you to create a separate network with limited access to local devices. The code for such a network can be easily generated and shared with guests.
Frequently Asked Questions (FAQ)
Is it possible to scan a Wi-Fi code if the internet on my phone is turned off?
Yes, the scanning and decoding process doesn't require an internet connection. The camera reads the graphic pattern locally. However, connecting to a Wi-Fi network requires a working router.
Why doesn't Redmi connect automatically after scanning?
The network may be hidden, require additional browser confirmation (captive portal), or the password in the code may be out of date. Also, check whether airplane mode is enabled or Wi-Fi is disabled in the system.
Does this method work on older versions of MIUI (MIUI 10, 11)?
QR code scanning was available in earlier versions, but in MIUI 10 and 11, it was only available through the Scanner app, not the main camera. MIUI 12 and later offer expanded functionality.
How to save a scanned code to the gallery?
Your smartphone doesn't automatically save the code image to your camera roll when you scan it. To save it, you'll need to ask the network owner to take a screenshot of the code or photograph it with another phone.
