Xiaomi’s modern smartphones have long since ceased to be just callers, becoming powerful digital space management centers. One of the most sought-after features in everyday life is the ability to instantly transfer Internet access to guests or their other devices without having to dictate complex combinations of characters. Owners of devices based on the shells of MIUI and the new HyperOS often wonder how to effectively implement this process, since standard Android methods here can work with some features.
The Chinese giant's ecosystem offers several proven ways to do this, each with its own advantages depending on the situation. QR-It's a code, a camera scan, or even a special widget on your desktop, and understanding the nuances of wireless networks in your device's interface will save you time and avoid errors when you enter data manually.
In this article, we will take a look at all the available algorithms for transferring access keys. We will look at the regular system tools, camera capabilities and third-party utilities that can be useful in unusual situations. Regardless of the model of your smartphone, whether it is a budget Redmi or flagship Xiaomi, the methods described will be relevant and help establish a connection in seconds.
Use of built-in QR-code-setting
The most reliable and fastest way to transfer data to connect is to use the built-in functionality of the operating system. MIUI HyperOS developers have integrated the generator QR-To activate this mode, the user must go to the wireless settings section, which displays the current active connection.
Once you log into the network details menu, a square barcode will appear on the screen, containing encrypted network SSID and password information, and guests can only point their smartphone camera at your device screen, and the system will automatically prompt you to connect, which eliminates the human factor, since it eliminates the possibility of error when manually entering characters.
It is important to note that the screen of the source device must be bright enough to work in this function. If the display is too dim, the camera of the receiving device may not read the code the first time. In addition, some Xiaomi smartphones allow you to configure the display of this code through widgets on the desktop for even faster access.
There is also the option of saving an image of the code to the gallery to send it remotely via messengers, although it is less secure in terms of network perimeter protection.In a standard use case, it is enough to keep the phone unlocked in the appropriate menu.
💡
Increase the brightness of the screen to a maximum before the guest scans the code – this will speed up recognition and prevent errors in reading the matrix.
Scanning. QR-Xiaomi camera code
The reverse process, when your phone acts as a scanner, is also implemented as conveniently as possible. The camera in Xiaomi smartphones is equipped with an intelligent recognition module that automatically determines the types of content. You do not need to look for a separate application - just run a standard Camera application and point the lens to the code.
When the system recognizes in the frame QR-A code with network data will show a pop-up notification asking you to connect, and clicking on it will instantly take you to the settings menu, where the connection will be established automatically. This is especially convenient when you come to visit and do not want to ask for a password from the hosts, if the code is placed, for example, on a business card or on the table.
In some firmware versions, the camera functionality may require special scanner or document modes to be enabled if automatic recognition fails, and it’s also worth making sure that geolocation access is activated in the camera app permissions, as this is an Android security requirement for network profiles.
What if the camera doesn’t see the code?
Alternative methods of data transmission
If for some reason the screen is damaged or the function is QR-There are other ways to share the access, and one of them is to use the function. NFC, If both devices support this standard of communication, just hold the backs of the smartphones to each other, and the data will be transmitted instantly.
Another option is to use widgets on the desktop. MIUI allows you to add special shortcuts that, when pressed, immediately open the menu with QR-You can code it or copy it to the clipboard, and it saves time because it doesn't require you to go deep into the settings menu every time.
For advanced users, a method of creating a shortcut through system settings or third-party launchers is available, which displays network information in the form of a text message, but this method is less convenient for ordinary users and requires preliminary preparation of the device.
In emergency cases, you can use the “Share” feature in the network properties menu, if it is available in your version of the software, this will allow you to send a text file or link via Bluetooth or messenger, although the password in this case can be hidden by asterisks depending on the version of Android.
Setting up the guest mode of the Xiaomi router
When it comes to constantly giving access to friends or customers in the office, the best solution is to set up a guest network on the Xiaomi or Mi Router router itself.This creates an isolated segment of the network that does not have access to your personal files, printers and smart devices in the house.
The guest network allows you to set individual rules, like a speed limit or a traffic limit for connected devices. QR-code for the guest network and even print it out so guests can connect at any time without you being involved.
To activate, you need to log into your router's settings, find the Guest Network and activate it, and you can set a network name (SSID) and a complex password that only applies to that segment, which increases the overall cybersecurity of your home infrastructure.
💡
Using a separate guest network is the best way to secure personal data from third-party devices connecting to your Wi-Fi.
Solving Connection Problems
Despite the simplicity of the technology, users sometimes have difficulty sharing. Often the problem lies in the incompatibility of frequency bands: if the router distributes the network only in the 5 GHz band, and the guest device supports only 2.4 GHz, the connection will not take place.
Another common mistake is the incorrect system date and time on the guest's device: Security protocols require time synchronization to ensure that certificates work correctly. If the clock is downed, the phone may simply not see the network or reject the connection, even if the password is correct.
It's also worth checking if the router's connected devices limit is reached. Many home routers have a limit on how much they can use. 10-15 If the limit is exhausted, new devices will not be able to get to the same customers. IP-Address and you will see an error "I failed to connect».
| Problem | Possible cause | Decision |
|:--- |:--- |:--- |
| The camera does not read the code | Low brightness or dirty lens | Wipe the camera and increase the brightness of the screen |
| Authentication error | Incorrect password or encryption type | Check router security settings (WPA2/WPA3) |
| Network visible but no internet | ISP or router problems | Restart router |
| Phone does not see 5GHz network | Device does not support 5GHz | Switch router to 2.4GHz or mixed |

Security issues in the transfer of access
By passing on a password, you are actually giving the keys to your digital home. It's important to understand that once connected, the device accesses the local network. If you're hosting guests frequently, it's recommended that you change the password of the main network regularly or use the separate guest access point mentioned earlier.
You don't have to use simple passwords like 12345678, which are easy to match. Xiaomi's modern routers allow you to generate complex encryption keys. QR-The risk of interception is minimal, since the code is valid only at the time of scanning and is not transmitted over open communication channels.
⚠️ Warning: Never send screenshots QR-And then you can use a password code to a public chat room or a public group, and anyone with access to a history of correspondence can read the code and connect to your network.
Also keep an eye on the list of connected customers in the router app. If you notice an unfamiliar device, lock it immediately and change your password. Modern HyperOS security systems can notify you of new connections, which allows you to keep the situation under control.
