Modern Xiaomi smartphones running MIUI or HyperOS offer users a variety of convenient features for everyday use. One such useful feature is the quick exchange of network settings using visual codes. This solution eliminates the need to dictate complex passwords or manually enter long character combinations, which is especially useful if you frequently change devices or have guests over.
QR code generation and scanning technology is built directly into the Android operating system settings. You don't need to install any third-party apps, as the standard interface provides all the necessary tools. Data exchange is instant and uses secure encryption, ensuring your network is protected from unauthorized access.
In this guide, we'll walk you through how to generate a code to connect to your network on a Xiaomi phone. You'll also learn how to scan an image from another device and any potential setup issues.
Benefits of using QR codes for internet access
Using visual codes to communicate network settings has become a de facto standard in the mobile technology industry. The main advantage lies in connection speed: guests don't have to ask for a password, and you don't have to dictate it, risking typing errors. Simply showing your smartphone screen is enough.
Furthermore, this method eliminates human error when entering data. Users won't confuse the number zero with the letter O or miss an uppercase character. The system automatically reads the SSID and security key, immediately establishing a connection to the router.
From a security standpoint, this approach also has its advantages. You don't have to voice the password out loud, which is important in public spaces or open-plan offices. Once connected, the guest gains access to the network but won't see the password in plain text on their screen unless they have special access rights.
For device owners Xiaomi And Redmi This feature is implemented as natively as possible. Unlike some other manufacturers, there's no need to create widgets or delve into deep Wi-Fi settings menus to share access. Everything is located on the interface surface and accessible with a couple of taps.
- 🚀 Instant connection without manually entering characters.
- 🔒 Increased password confidentiality during transmission.
- 📱 Native system support without installing add-ons.
- 🔄 Convenience when changing devices or connecting tablets.
⚠️ Warning: The QR code contains your password in plain text. Do not take screenshots of the guest network access code or share them publicly, as anyone can read the data and connect to your router.
Generating a QR code on a Xiaomi smartphone
To share internet access, your phone must already be connected to the desired Wi-Fi network. Creating an image for scanning takes just a few seconds and is performed through the standard settings menu. The interface may vary slightly depending on the version. MIUI or HyperOS, but the logic remains the same.
First, open the Settings app and go to the Wi-Fi section. A list of available networks will be displayed, and the currently active connection will be marked with a corresponding icon. Tap the name of the network you're connected to or the arrow to the right of it to expand its options.
In the menu that opens, you'll see the network name, frequency, and a button to connect. Below that is usually a field with IP address parameters. This is where the "Share" button or QR code icon is located. When you click it, the system may require you to unlock your device with a PIN or fingerprint for security purposes.
After successful authentication, a large image will appear on the screen, which the other device will scan. The image is often accompanied by a text password, which can be copied or rewritten manually if the second device's camera is not working.
It's important to note that the generated code is valid indefinitely until you change the router password. However, if you change the router password, the old generated code will no longer work, and devices will be unable to connect.
How to scan the code and connect to the network
To connect to the network using a QR code on a Xiaomi device, you'll need a camera or built-in scanner. Modern versions of MIUI allow you to scan codes directly through the Camera app without launching additional apps. This simplifies the process and makes it more intuitive for the user.
Point the camera lens at the image, holding the phone still for 1-2 seconds. The system will automatically recognize the pattern and prompt a pop-up notification to connect to the Wi-Fi network. Confirm the action by tapping the "Connect" button.
If the standard camera doesn't respond to the code, you can use the built-in scanner in the notification shade. Swipe down from the top of the screen to open the Control Center and look for the "Scanner" icon. This tool is often more sensitive to complex or corrupted codes.
There's also an alternative method via Wi-Fi settings. Go to the wireless networks menu and select "Add network" or "Connect via QR code" (the location depends on your Android version). Here, you can select an image from your gallery if the code was previously saved as an image.
☑️ Connection algorithm
After confirmation, the system will automatically fill in all the necessary parameters and log you into the network. The connection status will be displayed at the top of the screen, and an active connection icon will appear next to the network name.
Setting up guest access via QR code
To ensure the security of your main network when frequently hosting guests, we recommend using the guest mode feature. On Xiaomi routers and in MIUI settings, you can create a separate network with limited access. The QR code for this network is generated in a similar way, but it leads to an isolated segment.
A guest network allows you to limit data transfer speeds and block access to local resources, such as printers or network storage. This is ideal for parties or gatherings where you need to provide internet access to dozens of devices without compromising the security of personal files.
To activate this mode, go to the router settings via the app. Mi Wi-Fi or web interface. Find the "Guest Network" section, enable it, and set the time interval. Then, generate a QR code for this specific network using a connected smartphone.
Using a separate SSID for guests also helps avoid overloading the main connection. Guest devices won't interfere with smart home functionality or video streaming on the TV, as traffic will be distributed more evenly.
- 🛡️ Isolate guest devices from your personal local network.
- ⏳ Possibility to set an access timer.
- 📉 Limit the maximum speed for external users.
- 🚫 Blocking access to the router admin panel.
⚠️ Note: The guest network setup interface may vary depending on the Xiaomi router model. Some budget models only support one guest network, while flagship models allow you to create multiple profiles.
Comparison of connection methods: QR vs. manual input
Understanding the differences between connection methods helps you choose the optimal scenario for each situation. Below is a table comparing the key features of QR code connection and traditional manual password entry on Xiaomi devices.
| Parameter | QR code | Manual input |
|---|---|---|
| Connection speed | 1-3 seconds | 10-30 seconds |
| Risk of error | Absent | High (especially with complex passwords) |
| Required actions | Point the camera | Find the network, enter the password, confirm |
| Security | Medium (risk of screenshot) | High (with hidden input) |
| Support for older devices | Requires Android 10+ / iOS 11+ | Supported by all devices |
As the comparison shows, QR codes are faster and more convenient, but they require a modern camera and operating system on the receiving device. This method is not suitable for very old tablets or feature phones.
On the other hand, manual entry remains a universal, but labor-intensive, method. It's indispensable if the network is hidden (doesn't broadcast its SSID) or if the smartphone screen from which the code needs to be read is broken and doesn't display the image clearly.
For an office environment or coworking space where people are constantly changing, using QR codes at the reception desk is a service quality standard. This creates the impression of technological advancement and respect for the customer's time.
Troubleshooting connection issues
Despite the simplicity of the technology, users sometimes encounter difficulties. The camera may fail to focus on the code, or the phone may refuse to connect after scanning. Most often, the problem lies in a dirty lens or excessively bright light, creating glare on the source screen.
If your device displays "Incorrect password" or "Unable to connect," check the date and time on your smartphone. Time desynchronization can lead to security certificate errors, which can prevent successful handshake with the router.
Another common cause is that the network memory is full. Android has a limit on the number of saved Wi-Fi profiles. If the limit is reached, new connections won't be established until you remove old, unused networks from the list of saved networks.
It's also worth considering the frequency range. Some older devices only support 2.4 GHz, while a QR code may lead to a 5 GHz network. Make sure your device is compatible with the network standard you're trying to connect to.
What to do if the camera does not see the code?
Try changing the distance to the screen (usually 15-20 cm). Clean the camera lens. Turn on the flash if it's dark. If this doesn't help, use a third-party scanner app from the Play Market.
If all else fails, reset your network settings. This will reset all saved passwords and Bluetooth pairings, but it often resolves deep software conflicts with Wi-Fi drivers.
FAQ: Frequently Asked Questions
Is it possible to create a QR code for a hidden network (Hidden SSID)?
Technically, this is possible, but difficult to do using standard Android tools. Hidden networks require precise network name and encryption type. The QR code for such a network must contain the full profile, including the exact SSID, which is not broadcast. This usually requires special code generators.
Is it safe to save a QR code screenshot to the gallery?
No, it's not secure. The screenshot contains all the information needed to access your network in plain text. If an attacker gains access to your gallery or you send the photo to someone, they can easily extract the password. It's best to regenerate the code as needed.
Why can't my iPhone see my Xiaomi QR code?
Apple devices (iOS 11 and later) fully support standard Wi-Fi QR codes. If you can't connect, check whether Airplane Mode is enabled on your iPhone or whether automatic connections to unknown networks are blocked in your privacy settings.
Does this method work on tablets without a camera?
On Xiaomi tablets without a camera, you won't be able to scan the code, but you can use the "Share" feature to transfer the password to another Xiaomi device via Mi Share. To connect to the network, you'll need to enter the password manually or use a USB data cable.
Is it possible to decipher a password by looking at a QR code?
Yes, there are many online services and apps that allow you to decode QR codes and display the contents in text format. This is why you shouldn't trust codes from unknown sources and should keep your codes safe from prying eyes.
