How to enable connection QR-Wi-Fi code on Xiaomi devices: from smartphone to router

Tired of typing complex Wi-Fi passwords into every new device? Xiaomi’s QR-code connection solves this problem in seconds — just scan the code with a smartphone camera or a special app. But not everyone knows how to activate this option on different devices of the brand, from the flagship Xiaomi 14 Ultra to the budget Redmi Note 12 and Mi Router AX6000 routers.

In this article, we will discuss all ways to include QR-code for Wi-Fi on the Xiaomi ecosystem, including hidden HyperOS settings, features of working with Mi Home and nuances of compatibility with Android devices 13/14. You will learn why code is sometimes not read, how to get around the restrictions on older models and what to do if the function is Suddenly disappeared after an update.

1. how the connection works by QR-Xiaomi code: technical details

Technology QR-Xiaomi's Wi-Fi code is based on the Wi-Fi Easy Connect standard (formerly known as Wi-Fi Device Provisioning Protocol), which allows network data to be transmitted encrypted:

🔹 Dynamic encryption: code is regenerated with each request, which eliminates the possibility of interception;
🔹 Bilateral Authentication: Scanner Device and Access Point mutually authenticate;
🔹 Support WPA3: on new models (Xiaomi) 13T Pro, POCO F5) The code automatically configures the most secure protocol.

It's important: QR-The code does not contain the password itself, but an encrypted access token that is valid for a limited time (usually 2-5 minutes), which makes the method safer than sending a password through messengers or notes. MIUI 12.5 and older there is a bug: if you disable the access point immediately after the code is generated, the token may become invalid.

💡

If you often connect guests, create a separate guest network in the settings of the Xiaomi router and generate for it. QR-This will keep the main password secret, and guests will only have access to limited traffic.

2. Turn it on. QR-Wi-Fi code on Xiaomi smartphones (HyperOS/MIUI)

On most Xiaomi smartphones, the feature is activated via the standard settings menu, but the path may differ depending on the firmware version. Here is a universal guide for HyperOS (2026) and MIUI 14:

🔄 Xiaomi 12 Lite: Reset your network settings (Settings) → System system → Reset → Wi-Fi reset).

The device is connected to the desired Wi-Fi network|The firmware version is not lower. MIUI 12.5|Disabled. VPN proxy|The camera of the smartphone scanner works properly-->

On HyperOS (for example, Xiaomi 14), the algorithm is simplified: just hold your finger on the network name in the Wi-Fi list, and a context menu will appear with the item Share via QR. Also supported dynamic QR, which is updated every 30 seconds for increased security.

3. Features on Xiaomi routers (Mi Router, AX-series)

On Xiaomi routers QR-The code for the connection is generated via a web interface or the Mi Wi-Fi app:

Model router	Method of generating QR	Features
Mi Router 4A	Mi Wi-Fi app → Home → QR icon next to network name	Requires the latest version of the software (4.4.25+)
AX3600	Web interface (192.168.31.1) → Wi-Fi → Settings → QR-code	Supports guest networks
AX6000	Xiaomi Home → Devices → Router → Share icon	QR is 10 minutes in effect.
Mi Router Mini	Only via Mi Wi-Fi (old version)	No support for WPA3

⚠️ Note: On routers with Developer firmware ROM function QR-The code can be disabled by default. To activate it, go to Advanced Settings. → System Tools → QR Code Share and turn on the switch.

The AX9000 and later have a "Disposable QR" option, which automatically deactivates after the first successful connection, which is useful for public areas where access is restricted.

4.Problems with QR-Code: Why it doesn’t work and how to fix it

If QR-The code is not read or gives an error "I failed to connect", check the following points:

🔄 Reboot devices: Turn off Wi-Fi on your smartphone and router for 30 seconds, then try again;
📶 Network signal: If the signal level is below 2 divisions, some devices (e.g. Redmi Watch 3) will not be able to connect;
🔒 Type of encryption: QR-The code does not work with the networks where it is used. WEP or the Open Network;
📱 Compatibility: iOS devices (iPhone) cannot read QR From Xiaomi directly – you need an intermediary (Android-smartphone).

A common error on the POCO M4 Pro and Redmi Note 11: after scanning the QR, the message "Incorrect format" appears. This is due to a bug in MIUI 13.0.3-13.0.7.

Update the firmware to MIUI 13.0.9+
Or retrace to MIUI 12.5.7 via Fastboot.
Or use a third-party scanning app (e.g. QR & Barcode Scanner).

What to do if QR-The code is generated but not scanned?

The problem may be in the camera of the smartphone scanner. Try: 1. Wipe the camera lens from dirt. 2. Enable Macro mode (if any). 3. Use another device to scan. 4. Increase the brightness of the screen on the device that generates QR (sometimes the code is poorly read at low contrast). If nothing helps, generate the code again - it may have expired.

On Xiaomi routers with dual-band Wi-Fi (2.4 GHz) + 5 GHz) QR-The default code is only created for the 2.4 GHz network. To connect to 5 GHz, you need to:

log into the router's web interface;
Go to Wi-Fi → 5G settings;
Activate the option Enable QR-code 5G.

5. Alternative ways of connecting without QR-code

If the QR function is not available or works, use alternative methods:

🔑 WPS (Wi-Fi Protected Setup: Press the button WPS on the router, then select this option in the Wi-Fi settings on your smartphone. 3/4 most AX-model;
📎 Mi Share: HyperOS allows you to transfer Wi-Fi data via Settings → Connections → Mi Share (required) MIUI 14+);
📋 Export configuration: On Xiaomi router, export your Wi-Fi settings to a.conf file, then import it on another device via Mi Wi-Fi;
🤖 Voice assistant: on smartphones with Google Assistant say: “Connect to my Wi-Fi” – the system will offer options.

6.Security: risks and how to avoid them

Despite the convenience of connecting to QR-The code has potential vulnerabilities:

🕵️ Code Interception: If someone can scan QR Before you, it will have access to the network. Always generate code in a safe place;
📡 Switching the access point: attackers can create a fake network with a similar name and offer their own QR-code;
🔄 Caching: on some devices (Redmi) 9A) QR-The code is saved in the gallery - delete it after use.

To minimize the risks:

Use QR only for trusted devices.
On Xiaomi routers, activate DNS Switch Protection in Settings → Security;
Check the list of connected devices in Mi Wi-Fi regularly.
For guest access, set up a separate network with a speed limit.

⚠️ Note: On devices with root rights (root) or custom firmware (LineageOS) QR-The code may contain unencrypted network data. ADB-Debug and verify system integrity through Security App.
