Modern Huawei smartphones running EMUI or HarmonyOS offer users a variety of ways to simplify their interactions with wireless networks. One of the most convenient and fastest methods is connecting to Wi-Fi using QR codeThis mechanism eliminates the need to manually enter long and complex passwords, which is especially useful when granting access to guests or quickly connecting a new device, such as a tablet or smart speaker.
The functionality for generating and reading codes is built directly into the system settings. Huawei, making the process extremely simple and requiring no third-party apps. However, despite its simplicity, many users don't know where to find this option or how to properly use it for internet tethering. In this article, we'll take a detailed look at all the nuances of working with QR codes on devices from this Chinese brand.
We'll cover not only standard connection scenarios but also address potential issues that may arise when using this feature. Understanding how it works security When transferring data via a graphic key, you can be confident that your personal network is protected from unauthorized access.
Benefits of using a QR code to access the network
Using a pattern to log in to your network significantly speeds up the connection process. You no longer need to spell out your password or search for it in your router's address book. Simply hold the camera of one device close to the screen of the other. This is especially convenient when the password contains complex characters whose case is easily confused.
In addition, this method increases the level security Your local network. You can generate a temporary code for a guest without having to reveal the main Wi-Fi password. After your guests leave, you can easily change the password in the router settings, and the old QR code will no longer work, preventing unauthorized access.
- 🚀 Instant connection without manually entering characters
- 🔒 Hiding your real password from prying eyes
- 📱 Universal for any device with a camera
- 🔄 Ability to quickly change access without explanation
⚠️ Warning: The QR code contains an encrypted password for your network. Never share photos of it on public sources or social media to prevent unwanted users from connecting.
Importantly, the technology operates on standard protocols, so the code generated by Huawei is easily read by devices from other manufacturers, including iPhone, Samsung, and Xiaomi. This makes the method ideal for mixed-system environments in the home or office.
Generating QR codes on Huawei and Honor smartphones
You don't need any special apps to create a connection image. All the necessary functionality is already integrated into the operating system interface. The process may vary slightly depending on the OS version. EMUI or HarmonyOS, but the general logic remains the same for all models of the brand.
First, make sure your smartphone is already connected to the Wi-Fi network you want to share. If you're not an authorized client of the network, the system won't be able to generate a valid access code. Once connected, go to the device's main settings menu.
☑️ Check before generation
Next, open the section Settings and select the item Wi-FiFind the active network you're currently connected to in the list. Click the network name or the gear icon next to it to open advanced connection settings. This is where the option you're looking for is located.
In the menu that opens, you'll see a QR code. On some firmware versions, it's displayed directly below the network name; on others, you'll need to press a button. Share or a square with arrows icon. The system may require identification via a fingerprint scanner, facial recognition, or a screen unlock PIN.
| EMUI/HarmonyOS version | Button location | Authorization required |
|---|---|---|
| EMUI 10 / 11 | Under the network name (QR icon) | Yes (PIN/Biometrics) |
| EMUI 12 / 13 | Share button | Yes (Biometrics) |
| HarmonyOS 2.0 | In the center of the Wi-Fi settings screen | Yes (PIN/Biometrics) |
| HarmonyOS 3.0/4.0 | Clicking on the network name | Yes (Biometrics) |
After successful identification, a large image will appear on the screen, which can be shown to the other party for scanning. You often also have the option to save this image to your gallery or send it via messaging, which is convenient for pre-clearing access.
How to scan codes to connect to Wi-Fi
If your goal isn't to share data, but to connect your own Huawei device to the network using a code, the process is also extremely simplified. You don't need a dedicated scanner app, as this feature is built into the standard camera app and settings menu.
The fastest way is to open the app Camera and point the lens at the QR code. The system will automatically recognize the type of encoded data and prompt a pop-up notification about connecting to a Wi-Fi network. Simply tap it, and the smartphone will automatically log in to the network.
- 📸 Point the camera at the code without launching any apps
- 🔔 Wait for the pop-up notification to appear on your screen
- ✅ Click "Connect" to automatically log in
- 📂 Alternatively, use the scanner in the Wi-Fi menu
An alternative method involves using the built-in scanner in the wireless network settings. Go to Settings → Wi-Fi and at the bottom of the screen (or in the upper corner, depending on the version), find the scanner icon. Clicking it will launch a scanning interface optimized for finding networks.
This method often works more reliably in poor lighting or damaged QR codes, as the algorithms focus specifically on searching for network profiles, ignoring other types of QR codes. After reading the code, the device will immediately attempt to establish a connection.
What to do if the camera does not see the code?
Make sure the camera lens is clean. Try adjusting the distance to the screen—sometimes autofocus can't focus at too close a distance. Also, check that "Macro" mode isn't enabled, as it can distort the image of large codes. If the problem persists, use the built-in scanner in the Wi-Fi settings menu; it often has a more sensitive recognition algorithm.
Setting up guest access via Huawei Wi-Fi routers
Owners of Huawei brand routers (AX3, WS7100 series, and others) have access to advanced functionality via a mobile app. Huawei AI Life or a web interface. Here you can generate separate QR codes for a guest network, which is isolated from your main home network.
A guest network is a great way to protect your personal files, printers, and smart home from visitors' devices. By setting up this access, you create a separate internet channel with your own username and password, which can be easily shared via a QR code.
To configure, enter the router management application, select the section My Wi-Fi or Guest networkActivate this mode and set parameters such as access duration or speed limit. After saving the settings, the system will prompt you to generate a QR code specifically for this guest hotspot.
⚠️ Note: The Huawei AI Life app interface may be updated. If you don't see the "Guest Network" option, check the "Tools" section or update your router firmware to the latest version.
Using a separate guest network also allows you to easily control the number of connected devices. You can disable guest mode at any time with a single tap in the app, and all guests will lose access, while your personal devices will continue to operate without interruption.
Possible problems and solutions
Despite the technology's robustness, users may encounter errors when generating or reading codes. Most often, these issues are related to software interface glitches or incorrect security settings. Understanding the causes helps quickly troubleshoot problems.
One common issue is the inability to generate a code if the password uses specific characters or if the network is operating in compatibility mode with older standards. In such cases, the system may simply not display the (Share) button.
- 🔄 Restart your smartphone to reset network services
- 📡 Make sure you are using the WPA2/WPA3 security protocol
- 🔐 Check if password copying is disabled in corporate profiles
- 📱 Update the Huawei Services app or system settings
If the QR code is generated but other devices can't connect via it, check the frequency range. Some older devices can't connect to 5 GHz networks via QR code unless the code explicitly specifies the range. In this case, try switching your router to dual-band mode with separate network names or force it to use 2.4 GHz.
It's also worth keeping in mind that on devices with Google services (GMS) installed via third-party methods or on global firmware versions, the password encryption algorithm may differ from Chinese versions. If the code isn't readable on your iPhone, try changing the encryption type in your router settings.
| Problem | Probable cause | Solution |
|---|---|---|
| The code is not generated | The network is hidden or corporate | Make the network visible in the router |
| Error while scanning | Low screen brightness | Increase the brightness to maximum |
| Incorrect password | The password has been changed | Generate a new code again |
| 2.4 GHz only | Range incompatibility | Separate network names in the router |
In rare cases, the issue may stem from the phone's memory being full, preventing the system graphics generation service from creating the image. Clearing the system cache or restarting the device usually resolves this issue.
Security and Best Practices
While technology is convenient, it carries certain risks if used carelessly. A QR code is essentially an open password. Anyone who takes a photo of your phone's screen will have full access to the internet. Therefore, maintaining digital hygiene is essential.
Never leave your phone unattended in public places with a QR code open. If you're showing the code to a friend, hold the device in your hand and supervise the scanning process. It's a good idea to change your router password after guests have left, especially if you're partying with a large group of strangers.
⚠️ Warning: Don't use QR codes to connect to public networks in cafes or airports unless it's an official code from the establishment. Attackers can replace the code with their own to intercept your traffic.
For your home network, we recommend using the guest access feature mentioned earlier. This isolates your smart lights, security cameras, and NAS storage from other people's smartphones. Even if a guest device is infected with a virus, it won't be able to attack your main devices.
Regularly check the list of connected clients in the router app. If you see an unfamiliar device, block it immediately and change the password. Early detection of an intrusion helps minimize damage.
Following these simple rules will allow you to enjoy the speed and convenience of Huawei technology without sacrificing the security of your digital environment. Technology evolves, and with it, new security methods emerge, but basic user caution remains the most important factor in security.
