How to connect your phone to Wi-Fi via QR code: Complete instructions for Android and iOS

Connecting to Wi-Fi via QR code is the fastest and most convenient way to connect your smartphone to a wireless network without having to manually enter a lengthy password. This is especially useful for guest networks in cafes, hotels, or offices, where passwords are often complex and comprised of random characters. But even at home, a QR code simplifies connecting new devices: just scan the code once, and your phone automatically receives all the network settings.

The technology works on all modern smartphones, from budget ones Xiaomi Redmi to the flagship iPhone 15 Pro And Samsung Galaxy S24The main requirement is that the router must support QR code generation (almost all models since 2018 do), and the phone must have the latest version of the operating system installed. In this article, we'll walk you through the steps of connecting to Wi-Fi via a QR code. Android And iOS, and we will also talk about the nuances that may arise during the process.

What is a Wi-Fi QR code and how does it work?

A QR code for connecting to Wi-Fi is a graphical representation of all network parameters, including name (SSID), encryption type And passwordWhen you scan this code with your smartphone, the device automatically reads the data and connects to the network without any additional steps. This not only saves time but also eliminates errors when manually entering a password.

The QR code format is standardized: it contains a string of the form WIFI:S:<network_name>;T:<encryption_type>;P:<password>;;For example, for a network named MyWiFi, encryption WPA2 and password 12345678 the code will look like this:

WIFI:S:MyWiFi;T:WPA2;P:12345678;;

There are several ways to generate such a QR code:

• 📶 Via the router's web interface (most modern models) TP-Link, ASUS, Keenetic support this function).
• 🖥️ Using online generators (for example, Qifi or QR Code Generator).
• 📱 Android/iOS apps (e.g. QR & Barcode Scanner or WiFi QR).

⚠️ Note: Not all routers support QR code generation by default. If your model's web interface doesn't have this option, use third-party services to generate the code manually.

How to connect Android to Wi-Fi via QR code

On smartphones with Android 10 and later The QR code scanning feature for Wi-Fi is built into the system. You don't need to install any additional apps—just open the network settings. Here are the step-by-step instructions:

1. Open Wi-Fi settings: go to Settings → Network & Internet → Wi-Fi (on some models, for example, Samsung, the path may differ: Settings → Connections → Wi-Fi).
2. Click on the QR code icon: A scanner icon (📷) will appear in the upper right corner of the network list screen. Tap it.
3. Scan the code: Point the camera at the QR code (it can be on a sticker on the router, printed on paper, or displayed on the screen of another device).
4. Confirm connection: After reading the data, the system will prompt you to connect to the network. Click Connect.

If you have Android 9 or later, there may not be a built-in scanner. In this case:
