Modern technologies make life much easier for users, eliminating the need to remember complex passwords or enter them manually every time they change devices. Xiaomi This process is automated, allowing guests and family members to access the network in just a few seconds. Simply point your smartphone's camera at the special unlock pattern, and the connection is established instantly.
However, not everyone knows how to generate such codes on routers of this brand or how to create them on their own phone for traffic distribution. In this article, we will cover all the nuances of working with QR codes For Xiaomi devices, we'll look at Mi and Redmi router settings, as well as how to create tags for guest access without the hassle.
Using graphical keys has become the de facto standard for quick connection, especially in offices, cafes, and homes with numerous gadgets. This is not only convenient but also secure, as you can hide the actual password from prying eyes, allowing guests to connect without being able to see the security key.
How does fast connection technology work?
The method is based on a standard encryption protocol, where a connection string is encrypted in a graphic image. This string contains the network name (SSID), the encryption type (usually WPA/WPA2), and the password itself. When the smartphone camera reads the image, the operating system Android or iOS automatically recognizes the data format and prompts the user to join the network.
Devices Xiaomi And Redmi have built-in support for this function at the system shell level MIUI or HyperOSYou don't need to install third-party apps if you use the original software. The generation and reading process is native, guaranteeing stable operation.
⚠️ Attention: The QR code contains the password in clear text for anyone who knows how to decode it. Don't post generated images publicly accessible online if you don't want strangers using your Wi-Fi.
It's important to understand that an active internet connection is not required to read the code; a working Wi-Fi module and camera are sufficient. However, to generate the code on the router, initial setup is still required via the web interface or mobile app.
Generating a QR code on Xiaomi and Redmi routers
Router owners Xiaomi People often look for the ability to display a pattern lock directly in the device's interface so guests can connect quickly. Depending on the router model and firmware version, this feature may be located in different menu sections.
To get started, you need to log in to your control panel. Open your browser and enter the address 192.168.31.1 or follow the link miwifi.comEnter your administrator password. Once logged in, find the section for wireless network settings.
☑️ Check before setup
In newer firmware versions, this option is often hidden in the "Wi-Fi Settings" or "Security" menu. If the router's standard tools fail to generate an image, you can use the official app. Mi Wi-Fi for smartphones. It allows you to manage your router remotely and often includes a "Share Wi-Fi" feature that displays the desired unlock pattern on your phone's screen.
- 📱 Open the app Mi Wi-Fi on a smartphone connected to the router.
- 🔧 Go to the "Tools" or "Router Settings" section.
- 📡 Find the "Share Wi-Fi" or "Network QR Code" option.
- 🖼️ Take a screenshot of the image that appears or show the screen to the guest.
Some router models, especially international versions, may have a sticker with a QR code on the bottom panel. This code is used for initial device setup, but in some cases, it also contains the default network connection details if you haven't changed the security settings.
Create a QR code to share your phone's internet connection
If your smartphone Xiaomi Acting as an access point, you can easily create a pattern for your friends. This eliminates the need to dictate a password and allows guests to connect instantly. This feature is built into the standard system interface.
Go to your phone's settings and select "Wi-Fi hotspot". In some versions MIUI This option may be called "Move Access Point" or located in the "Connections and Sharing" section. Click on the name of your access point or the special sharing icon.
A QR code will appear on the screen containing all the necessary connection information. The guest points the camera, and their device automatically requests a connection to your network. The password remains hidden, increasing your device's security.
What to do if the code cannot be read?
If the camera doesn't recognize the image, try increasing the screen brightness on the smartphone that's being used as a transmitter. Also, make sure there's no glare on the screen and that the distance between the camera and the screen is 15-20 cm. Cleaning the camera lens can sometimes help.
It's worth noting that you can edit the access point settings before generating the code. Changing the network name or password will generate a new pattern. The old pattern will stop working immediately after changing the security settings.
Connecting guests via scanning
The connection process for guests is as simple as possible. They don't need to search for your network in the list of available networks or manually enter the necessary keys. Simply unlock your smartphone and launch the standard Camera app.
Point the lens at the QR code. A pop-up notification will appear on the screen prompting you to connect to a Wi-Fi network. Tapping it will automatically redirect you to the wireless network settings, where the connection will be established.
| User action | System response | Result |
|---|---|---|
| Pointing the camera at the code | Image analysis | Network SSID recognition |
| Clicking on a notification | Transferring data to the Wi-Fi module | Automatic password entry |
| Confirmation | Establishing a connection | Internet access has been obtained |
| Password error | Access denied | Request for re-entry |
It is important that the guest's smartphone has the QR code scanning function enabled. Most modern Android- On smartphones it is active by default in the camera application. iOS devices also do not require additional actions.
Using the Mi Home app to control access
Smart home ecosystem Xiaomi offers advanced access control capabilities through the app Mi HomeWhile it's primarily designed for managing smart home devices, some routers integrate with it, allowing you to create guest networks.
A guest network is a great way to secure your main home network. Guests only have internet access but can't see your personal files, printers, or other devices on the local network. This is especially important for smart home.
⚠️ Attention: Application interface Mi Home May vary depending on the region selected during account registration (China, Europe, Russia). Router functionality may also vary.
To set up guest access via the app:
- 🏠 Open the app Mi Home and select your router.
- ⚙️ Go to Wi-Fi settings.
- 👥 Activate the "Guest Network" option.
- 🔑 Set a separate name and password, then generate a code.
Using a separate guest network allows you to limit connection speeds for guests or set temporary access limits. This is useful if you're worried about someone hogging your bandwidth downloading large files.
Connection problems and their solutions
Despite the simplicity of the technology, users may encounter difficulties. Often, the problem lies not in the code itself, but in security settings or frequency bands. Routers Xiaomi support both 2.4 GHz and 5 GHz bands, and not all older devices understand codes for 5 GHz networks correctly.
Another common error is incorrect encoding format. If you're generating code using third-party online generators, make sure the correct encryption type is selected. For home networks, this is almost always the case. WPA/WPA2Using outdated WEP or an open network can result in connection failure on modern smartphones.
It's also worth checking whether the SSID hiding feature is enabled on your router. If the network name is hidden, a standard connection via QR code may not work, as the device won't know where to send the request, even after receiving the name from the code.
Safety and expert advice
Using QR codes significantly improves convenience, but requires security considerations. Avoid displaying codes for accessing the main network in visible locations outside your home or office. Any passerby with good eyesight or binoculars could theoretically scan the code and gain access.
It's recommended to change passwords regularly, especially if you frequently host large numbers of guests. Changing your password invalidates all previously issued QR codes, which is a good access control mechanism.
For businesses or offices, it is better to use specialized solutions for guest access with authorization via SMS or social networks, but for home and small offices, the method Xiaomi with QR codes is the optimal balance between convenience and security.
Is it possible to connect an iPhone to Xiaomi Wi-Fi via QR code?
Yes, smartphones iPhone iOS 11 and later support native QR code scanning to connect to Wi-Fi. The camera must be unlocked, but the app doesn't need to be open.
What to do if the camera doesn't see the QR code?
Try cleaning the lens, adjusting the angle, or changing the distance. Make sure the code is intact and well-lit. Also, check that the scanning function is enabled in the camera settings.
Does this method work for hidden networks?
No, if the network is hidden (SSID is hidden), the standard QR code connection mechanism may not work as the device will not be able to find the network for automatic pairing.
How to change the Wi-Fi password on a Xiaomi router?
Access the web interface at 192.168.31.1, go to Wi-Fi settings, and change the "Password" field. Don't forget to save the settings, after which you'll need to reconnect all devices.
Is there a limit on the number of connections via QR code?
QR code technology itself has no limits. The only limitations are your router's performance and the maximum number of clients it can handle simultaneously (usually 10-30 devices).
