How to connect WiFi via QR code on Xiaomi phone: a step-by-step guide

Technology is making our daily lives much easier by turning complex processes into a single touch. Until a few years ago, a long and complex password, often containing register symbols and numbers, was required to connect a new device to a wireless network, and now owners of Xiaomi, Redmi and POCO smartphones can instantly connect to the Internet by simply pointing the camera at a special square barcode.

This feature has become especially relevant in the post-pandemic era, when guests often have access to Wi-Fi and it is inconvenient to dictate a password every time. MIUI and the new HyperOS implemented powerful tools to work with QR-codes that are built directly into system utilities. You don't have to download third-party apps or search for hidden menus.

In this article, we will take a look at how to use a camera to scan access codes, how to generate your own guest code, and what to do if the automatic connection fails, and we will look at the nuances of how different versions of the shell work and offer solutions for common bugs.

Benefits of using QR-network-access

Using visual codes to communicate network data is not just a trend, it's a real time saving and security improvement. QR-code, you don't say your password out loud, which eliminates the risk of being eavesdropped by outsiders, and it's also ideal for people with disabilities or those who don't see small text on the screen.

The technology works on the basis of the WPA/WPA2 encryption standard, where the network name (SSID) and security key are graphically encrypted. The smartphone reads this data and automatically initiates the connection process. This eliminates the human factor: you can not miss spelling the letter "O" instead of the number "0" or confuse the register of characters.

⚠️ Note: Be careful when scanning QR-While connecting to Wi-Fi via code is secure, the code itself may lead to a phishing site or contain a malicious link unless it is standard Wi-Fi configuration code.

For Xiaomi device owners, this also means less stress on the on-screen keyboard and no need to search for saved passwords in router settings every time. If you have frequent guests or organize events, the ability to quickly “distribute” the Internet becomes a critical feature.

Preparation of Xiaomi smartphone for scanning

Before you start scanning, make sure your device is ready to work with wireless modules. In most cases, MIUI-based Android already has all the necessary permissions, but checking the basic settings will never be superfluous. The first thing you need to do is activate the wireless module.

Open the swipe control panel from top to bottom and make sure the Wi-Fi icon is blue or green. If the module is off, the system may not offer automatic connectivity even after successfully reading the code. It's also worth checking if the flight mode is on, which locks all radio modules.

The camera is important. In the newer versions of the HyperOS shell, the recognition algorithms are faster, but they need access to the lens. Make sure the camera lens is clean, without greasy spots or dust, which can make it difficult to focus on the small details of the code.

If you plan to use this feature often, it makes sense to add a scanner widget to your desktop, which will allow you to run the function in a split second, without having to icon the Camera or Scanner app in the application menu.

Instructions: How to scan the code and connect

The connection process on Xiaomi, Redmi and POCO smartphones is as unified as possible, but there are slight differences depending on the version of MIUI. The fastest and most reliable way is to use the built-in scanner in the Camera application or system utility.

Point the camera lens at QR-Hold your phone steady so that the screen image is clear. The system automatically recognizes the data format as "Wi-Fi setting." A pop-up notification will appear on the screen asking you to connect to the network with the corresponding name.

Click on the notification. The system will redirect you to the Wi-Fi settings menu, where the network name will already be filled in, and you will only need to confirm the action with the "Connect" button. You do not need to enter the password, since it is already read from the code.

In some cases, if the code is damaged or the lighting is poor, automatic recognition may not work the first time, so try changing the phone's angle or distance to the code, and you can also use manual focusing by touching the area of the code on the screen.

How to create QR-Wi-Fi code for Xiaomi

Not only do you accept, but you also transfer access conveniently through visual codes. If you have friends, you don't have to dictate a complicated password. You can generate the code directly on your Xiaomi smartphone and show it to guests. You don't need third-party apps.

Go to the Settings menu and select the Wi-Fi section. Find the network you are currently connected to (it will be marked with a lock icon or a tick). Click on the network name or the arrow to the right of it to open additional settings.

In the menu you will see a large QR-And underneath it, you can have a share button or a scan icon, and you can click on it and send an image of the code through messengers (Telegram, WhatsApp), or you can just let the guest bring the phone to your screen.

For users who want to print the code and hang it in an office or cafe, there is an option to save an image. On some versions of MIUI, when you click on the code, a menu with the option "Save image" appears. If this option is not available, just take a screenshot and crop the extra one in the gallery.

Alternative methods of connection and setting

In addition to the standard camera, Xiaomi has other tools in its arsenal, such as the control center (curtain) often features a separate widget called "Scanner", which works faster, because it does not require loading the interface of a full camera with many filters and shooting modes.

Another method is to use the voice assistant Mi. AI Or Google Assistant. You can say, OK, Google, scan. QR-code, and the phone will start the appropriate mode. It's convenient when your hands are busy or the phone is lying on the table.

For advanced users who own ADB (Android Debug Bridge), there is the option of forcing the scanner to run or connecting to the network via the command line, although for the average user this is redundant. Standard MIUI methods cover 99% of use cases.

⚠️ Attention: When creating QR-Public access code (cafe, store) do not use the guest network code with full access to the router's admin panel. VLAN or limit access rights in router settings.

If you are using a Mi Home smart home, some devices also support configuration via a mobile phone. QR-The principle of reading remains the same: the smartphone camera recognizes the data and transmits it to the application to configure the device.

Solving Common Connection Problems

Despite the simplicity of the technology, sometimes there are crashes. The phone can see the code but not connect to the network, or not respond to scans at all. The first reason is often incompatibility of frequency bands. If the router only distributes 5 GHz, and the old phone supports only 2.4 GHz, the connection will not take place.

The second common problem is the wrong date and time on your smartphone. Security protocols require time synchronization to verify certificates. If your Xiaomi has a lost date, the network can reject the connection even with the correct password.

Also worth paying attention to is the limit of connected devices: routers have a limit on the number of concurrent customers. If the limit is exhausted, the new gadget will not be able to log in, even if the password (and code) is correct.

• 📶 Weak signal: Get closer to the router if the Wi-Fi indicator shows 1-2 division.
• 🔒 Lockdown MAC-Addresses: check if the router is not a filter on the MAC-Addresses that block new devices.
• 🔄 Mistake. DHCP: Try restarting the router if the phone says “Receive” IP-address..." infinitely.

💡

The most common cause of errors is a mismatch of security standards (WPA2/WPA3) between the router and the phone or a crowded buffer of router connections.
