• 📱 In the manufacturer's mobile application (for example, TP-Link Tether or Mi Wi-Fi).

If your router doesn't support QR code generation, you can generate a code manually on your smartphone or PC. To do this:

1. Install a QR generator app (for example, QR Code Generator or WiFi Key Share).
2. Enter the network name (SSID) and password.
3. Select the encryption type (WPA2/WPA3 — the most common).
4. Generate and save the code or share it.

3. Step-by-step instructions: how to connect to Wi-Fi via QR code on Redmi

Once the QR code is ready, all that's left to do is scan it with your smartphone. The process takes no more than 10 seconds, but requires several conditions:

• 📶 Your smartphone must have Wi-Fi is on (even if you are not yet connected to the network).
• 🔋 Battery level is at least 15% (when the battery is low, some MIUI functions are disabled).
• 📸 Your phone's camera should be able to focus on the code normally (wipe the lens if the image is blurry).

Now let's move on to action:

1. Open Settings on yours Redmi.
2. Go to the section Wi-Fi.
3. Click on the icon QR code in the upper right corner (or select Add network → QR code depending on the MIUI version).
4. Point the camera at the QR code. Make sure it fits completely within the scanner frame.
5. Wait for the notification to appear Connected to [network name].
