Scanning a Wi-Fi QR Code to Connect: All the Ways to Connect in 2026

Connecting to Wi-Fi by scanning a QR code is one of the fastest and most secure ways to connect a device to a wireless network without manually entering a password. This method works on smartphones, tablets, laptops, smart TVs, and even some printers. The main advantage is eliminating errors when entering a complex password and protection from prying eyes.

In this article, we'll cover all the current methods for scanning Wi-Fi QR codes: from standard Android and iOS features to specialized apps for Windows and Smart TVs. You'll learn how generate a QR code for your network, if it is not on the router sticker, and what hidden settings will help speed up the process. We'll pay special attention to security nuances—why you shouldn't scan codes from public stands and how to verify the network's authenticity before connecting.

This material will be useful for both beginners and experienced users: it includes basic instructions with pictures and advanced life hacks for automating the connection of multiple devices. All methods have been tested on current OS versions (Android 14, iOS 17, Windows 11) and popular router models (TP-Link Archer AX6000, ASUS RT-AX88U Pro, Keenetic Hero).

1. Where can I get a QR code to connect to Wi-Fi?

The QR code with your network details can be located in several places. The most obvious option is sticker on the bottom or back panel of the router. Usually the following is indicated there:

• 📡 Network name (SSID) - For example, KEENETIC-1234
• 🔑 Password — a combination of 8+ characters
• 🖼️ QR code - black and white square 3x3 cm

If there is no sticker or the code has been erased, there are three alternative ways to obtain a QR code:

1. Generate via the router's web interface. Go to the control panel (usually at 192.168.1.1 or tplinkwifi.net), find the section Wi-Fi → Security Settings and look for the option Show QR code (at Keenetic this is a tab Guest network).
2. Use the mobile appMost router manufacturers have official utilities (TP-Link Tether, ASUS Router, Mi Wi-Fi), where the QR code is displayed in the main menu.
3. Generate code manually using online generators (for example, qi-fi.org or qrstuff.com). To do this, you will need to enter the network name, encryption type (WPA2/WPA3) and password.

⚠️ Attention: Avoid scanning Wi-Fi QR codes found in public places (cafes, airports, shopping malls) unless they are posted on official operator stands. Attackers can spoof the codes to redirect traffic through their own servers.

2. Scan a Wi-Fi QR code on Android

Modern smartphones on Android 10+ Supports Wi-Fi QR code scanning without additional apps. Here are the step-by-step instructions:

1. Open Wi-Fi settings (swipe down and hold the Wi-Fi icon or go to Settings → Network & Internet → Wi-Fi).
2. Click on the icon QR code (usually in the upper right corner) or select Add network → Scan QR code.
3. Point the camera at the QR code. Make sure the code fits completely within the scanner frame.
4. Confirm the connection if prompted (on some devices, for example, Samsung Galaxy S23, you will need to enter your lock screen PIN).

If the standard scanner doesn't work (for example, on older versions of Android), use alternative methods:

• 📱 Google Lens: Open the app, point the camera at the code and select the link that appears. Connect to Wi-Fi.
• 🔍 QR scanner in your browser: V Google Chrome or Yandex Browser Open image search and select the scan option.
• 🛠️ Third-party applications: QR & Barcode Scanner (from Gamma Play) or Kaspersky QR Scanner (checks codes for security).

Disable VPN (may block connection)

Turn on Bluetooth (required for some router models)

Check that the camera is not covered by a case.

Update OS to the latest version-->

⚠️ Attention: On some firmware (for example, MIUI 14 on Xiaomi) after scanning the QR code, an error may appear "Unable to connect"In this case, reboot the router and try again, after first forgetting the network in the settings.

3. Connect via QR code on iPhone (iOS)

On iPhone And iPad With iOS 11+ Wi-Fi QR code scanning is integrated into the standard camera. The algorithm is simple:

1. Open the app Camera and go into mode Photo.
2. Point the lens at the QR code. The distance should be 15–30 cm for clear recognition.
3. Wait for the notification to appear Wi-Fi Network at the top of the screen and click on it.
4. Confirm the connection in the window that appears (on iPhone 15 Pro (Face ID or passcode will be required).

If the camera does not recognize the code:

• 🔦 Increase your screen brightness or illuminate the code with a flashlight.
• 📏 Make sure the code is not wrinkled or blurred (minimum size for scanning is 2x2 cm).
• 🔄 Restart the app Camera or restart your device.

On iOS 17 a function has appeared automatic connection to Wi-Fi via QR in the app Photo: If you take a photo of the code and open the photo in the gallery, the system will offer to connect to the network without any additional actions.

4. Scanning a QR code on a laptop (Windows, macOS, Linux)

Computers don't have a built-in QR code scanner, but there are several reliable ways to connect to Wi-Fi using a code:

For Windows 10/11

1. Install the application QR Code WiFi from Microsoft Store or WiFi QR Connect.
2. Open the program and point your webcam at the code (if you don't have a camera, upload an image of the code file).
3. Click Connect and wait for the connection (you may need confirmation in Network parameters).

For macOS

Use the built-in app Photo:

1. Take a photo of the QR code (hold the key Command + Shift + 4 for a screenshot of the area).
2. Open the snapshot in Viewing and press Tools → Show Code.
3. Follow the instructions to connect to the network.

For Linux (Ubuntu, Fedora)

Install the utility qrencode and a scanner zbar-tools:

sudo apt install qrencode zbar-tools
zbarcam --raw /dev/video0 | xargs -I{} nmcli dev wifi connect {}

After running the command, point the camera at the QR code - the system will automatically connect to the network.

⚠️ Attention: On Windows some antiviruses (for example, Avast) may block network connections via QR codes, viewing them as "suspicious activity." Temporarily disable network protection in your antivirus settings.

5. Connecting Smart TV and other devices via QR code

Smart TVs Samsung, LG, Sony And Xiaomi They support Wi-Fi connection via QR code, but the algorithm differs from smartphones. Here are instructions for popular brands:

Samsung (Tizen OS)

1. Go to Settings → General → Network → Open network settings.
2. Select Wireless Network → Connect via QR Code.
3. Scan the code using your TV camera (press on the remote control) Microphone and tell me Scan QR).

LG (webOS)

1. Go to Settings → Network → Wi-Fi connection.
2. Select QR code at the bottom of the screen.
3. Use the app LG ThinQ on a smartphone for scanning (the TV itself does not scan codes).

Xiaomi TV

On Xiaomi TV With MIUI TV:

1. Open Settings → Network → Connect via QR.
2. Point the camera (located on the top or side of the case) at the code.
3. Confirm the connection using the remote control (button) OK).

Why doesn't the TV see the QR code?

If your TV camera does not recognize the code, check:

1. Lighting - too bright or too dim light interferes with scanning.

2. Distance – optimally 30–50 cm from the screen.

3. Camera resolution - on budget models (for example, Xiaomi Mi TV A2) there may not be enough megapixels to read small codes.

4. Software updates - on Samsung QLED 2023 Without the latest firmware, the QR function may not work.

For devices without a camera (eg. Amazon Fire TV Stick or Apple TV) use companion app on smartphone:

• 📺 Fire TV: application Amazon Alexa → Devices → Connect to Wi-Fi.
• 🍎 Apple TV: Transfer Wi-Fi settings from iPhone through Settings → Accounts → Data Transfer.

6. Advanced settings: generating and editing QR codes

If you need create your own QR code For Wi-Fi (e.g. for guests or office), use the following services and commands:

Online generators

• 🌐 qi-fi.org - supports WPA3 and hidden networks (SSID).
• 🔗 qrstuff.com — allows you to add a logo to the center of the code.
• 🛡️ qrcode.monster — generates codes with passwords up to 63 characters long.

Local generation (without internet)

On Linux/macOS use qrencode:

echo "WIFI:S:my_network;T:WPA;P:my_password;;" | qrencode -o wifi_qr.png

For Windows download QR Code Generator Pro or use PowerShell:

[Reflection.Assembly]::LoadWithPartialName("System.Web")
$qr = New-Object System.Web.UI.WebControls.Image
$qr.ImageUrl = "https://api.qrserver.com/v1/create-qr-code/?data=WIFI:S:my_network;T:WPA;P:my_password;;"
$qr.RenderControl([System.Web.UI.HtmlTextWriter]::new([System.IO.StringWriter]::new()))

Editing existing code

To change data in a QR code (for example, update your password), use:

• 📱 QR Code Reader (Android/iOS) - shows decrypted code data.
• 💻 ZXing Decoder — online decoding tool (zxing.org/w/decode.jspx).

⚠️ Attention: Don't save Wi-Fi QR codes to cloud storage services (Google Drive, iCloud) without encryption. If the file is leaked, hackers will be able to connect to your network. For protection, use password-protected archives or specialized managers (e.g., Bitwarden for storing codes).

7. Troubleshooting QR code scanning issues

If your device does not connect to Wi-Fi after scanning the QR code, please check the following:

For diagnostics on Android use developer mode:

1. Activate the mode: Settings → About phone → Build number (press 7 times).
2. Go to Settings → System → Developer Options.
3. Turn on Wi-Fi Log and check the connection logs after scanning.

On iOS to analyze network problems:

1. Open Settings → Wi-Fi and click on the icon i near the network.
2. Check the parameters IP address, DNS And Router.
3. If the IP starts with 169.254, reset network settings: Settings → General → Transfer or reset → Reset network settings.

How can I check that the QR code points to the correct network?

Before connecting, decrypt the code using QR Code Reader. The correct format is:

WIFI:S:your_network_name;T:WPA2;P:your_password;;

If the network name (SSID) does not match your router, it is a fake code!

8. Security: How to protect your Wi-Fi from QR code leaks

QR codes are convenient, but they can become a vulnerability if they fall into the wrong hands. Follow these rules:

• 🔐 Restrict access to code: Do not place it in public places (such as on an office door). Use guest network for temporary connections.
• 🔄 Change your password regularlyEven if the QR code leaks, changing the password on the router will invalidate it. Set up automatic password change in 192.168.1.1 → Wireless Network → Security Settings.
• 🛡️ Use WPA3: This encryption protocol (available on routers) ASUS RT-AX86U, Netgear Nighthawk RAXE500) protects against hacking even if the QR code is leaked.
• 📵 Disable WPS: This feature is vulnerable to brute-force attacks and may invalidate QR code security. Disabled in 192.168.1.1 → Wireless Network → WPS.

Wi-Fi QR codes with encryption type WEP or Open Network (No Password) can be decrypted in a few minutes using tools like Aircrack-ngAlways use WPA2-PSK or WPA3-SAE.

For additional protection:

• 🔗 Set up MAC filtering in the router so that only authorized devices can connect.
• 🕒 Enable Wi-Fi scheduling (for example, power outage at night) in 192.168.1.1 → Wireless Network → Schedule.
• 📡 Hide your SSID (turn off network name broadcasting), but remember that this does not protect against experienced hackers.

⚠️ Attention: Some public Wi-Fi hotspots (in hotels and airports) require authorization through a portal after connecting. A QR code is useless in this case—you'll still have to enter your username and password on the welcome page.

FAQ: Frequently Asked Questions about Scanning Wi-Fi QR Codes

Is it possible to connect to Wi-Fi via QR code if there is no camera on the device?

Yes, there are two options:

1. Take a photo of the code on another device (smartphone, tablet) and upload the photo to the scanner on your PC (for example, QR Code WiFi for Windows).
2. Decipher the code manually using online services (e.g. zxing.org) and enter the network data manually.

Why does it say "Saved, but without internet" after scanning the QR code?

This error occurs due to:

• Incorrect settings DHCP on the router (enable automatic IP assignment).
• IP address conflict (reboot the router and device).
