In the age of smart gadgets and lightning-fast internet, even connecting to Wi-Fi has become a piece of cake. Forget manually entering complex passwords with tons of characters—scanning is all it takes. QR code from the router's screen or another device. This method saves time, eliminates input errors, and works on most modern devices: from smartphones to Smart TV.
But how exactly does it work? Where can I get a QR code for my network, and which devices support this connection? In this guide, we'll cover all the details: from generating the code on the router to scanning it on iPhone, Android-smartphone or even Samsung TVWe'll also explain why this method is more secure than sending a password via SMS, and how to avoid common setup mistakes.
What is a Wi-Fi QR code and how does it work?
A Wi-Fi QR code is a graphical representation of your network data, encoded in a standard format. It contains:
- 📶 SSID (network name)
- 🔑 Password (in encrypted form)
- 🔄 Encryption type (WPA2, WPA3, etc.)
- 🌐 Hidden parameters (if the network is not broadcast)
When you scan the code with your smartphone or other device, it automatically recognizes the data and connects to the network without any additional steps. The main advantage of this method is Elimination of human error: you won't make mistakes in password characters or letter case.
QR codes for Wi-Fi support the standard WIFI: (For example, WIFI:T:WPA2;S:mynetwork;P:mypassword;;). This format is understood by all modern operating systems, starting with Android 10 And iOS 11Older devices may require third-party scanning apps.
Where can I get a QR code for my Wi-Fi network?
There are three main ways to get your network's QR code:
- Generate on the router - most modern models (TP-Link, ASUS, Keenetic, Xiaomi) can create code directly in the web interface.
- Create manually - using online generators (for example,
qi-fi.orgorqrcode.monster). - Copy from label - some routers (for example, Huawei or ZTE from providers) print the code on a sticker along with the password.
The most reliable option is to generate it through the router control panel. For example, on TP-Link Archer C6 the path will be like this: Advanced Settings → Network → Wireless → Wi-Fi QR CodeOn . Keenetic — System → QR code for connection.
| Router manufacturer | Path to the QR code in settings | Support in standard firmware |
|---|---|---|
| TP-Link | Advanced settings → Wireless mode → QR code |
Yes (since 2019) |
| ASUS | Wireless Network → QR Code |
Yes (RT-AX series) |
| Keenetic | System → QR code for connection |
Yes (all models) |
| Xiaomi | Wi-Fi → Settings → QR code |
Yes (AX series) |
| Zyxel | A third-party generator is required | No |
⚠️ Attention: If you are using a router from a provider (for example, Rostelecom or MTS), check if the QR code generation function is blocked in the firmware. Some operators disable it "for security reasons."
How to connect an Android smartphone to Wi-Fi via a QR code
Starting from Android 10, QR code scanning for Wi-Fi has become a standard feature. Here's a step-by-step guide:
Open "Settings" → "Wi-Fi"
Click on the QR code icon in the upper right corner
Point the camera at the code on the router screen or printout
Confirm connection-->
- Open
Settings → Network & Internet → Wi-Fi. - Tap on the icon QR code (usually in the upper right corner next to the add network button).
- Point the camera at the QR code. Make sure the code takes up at least 50% of the screen.
- Confirm the connection if prompted.
On some firmware (for example, MIUI on Xiaomi or One UI on Samsung) the path may differ slightly:
- 📱 On Xiaomi:
Settings → Wi-Fi → Advanced → QR code - 📱 On Samsung Galaxy:
Settings → Connections → Wi-Fi → Add network → QR code - 📱 On Realme/Oppo:
Settings → Wi-Fi → Scan QR code
If you have an older version of Android (below 10), install one of the scanning apps:
- 🛠️ QR & Barcode Scanner (from Gamma Play)
- 🛠️ WiFi QR Connect (specialized for networks)
- 🛠️ Google Lens (built into some models)
⚠️ Warning: QR code scanning apps may request access to your camera and storage. Install them only from Google Play And check reviews—some fake utilities steal data.
Connecting iPhone (iOS) to Wi-Fi via QR code
On iPhone And iPad With iOS 11 And the newer QR code connection works via the standard camera, but with one caveat: Apple hasn't added a dedicated scanning button like on Android. Instead:
- Open the app
Cameraand point the lens at the QR code. - Wait for the notification to appear
Wi-Fi networkat the top of the screen. - Tap the notification and your device will automatically connect to the network.
If the notification does not appear:
- 🔍 Make sure the QR code is generated in the correct format (must start with
WIFI:). - 🔍 Check that the function
Scan QR codesincluded inSettings → Camera. - 🔍 Try using the app Codes (from Apple) or Google Lens.
On iOS 14 and newer you can also:
- 📎 Save QR code in
Photo, then open it and tap on the linkConnect to Wi-Fi. - 📎 Use
Control Center: swipe down, hold the tileWi-Fi, then selectOther networks → Scan QR code.
Why can't my iPhone see my Wi-Fi QR code?
If your iPhone doesn't respond to a QR code, check:
1. Code format - it must be in the WIFI standard:, not in plain text.
2. Camera resolution - the code must be clear, without blurriness.
3. Network settings - if Wi-Fi is hidden (does not broadcast the SSID), connecting via QR may not work.
4. Regional restrictions - some operators (for example, in China) block automatic connection.
Connecting Smart TV and other devices via QR code
Modern Smart TV on Android TV, webOS (LG), Tizen (Samsung) or Google TV They also support Wi-Fi connection via QR code. However, the algorithm differs from that of smartphones.
For Samsung TV (2020 and newer):
- Go to
Settings → General → Network → Open network settings. - Select
Wireless Network → Connect via QR Code. - Scan the code with your TV camera (if you have one) or use the app SmartThings on a smartphone.
For LG TV With webOS:
- 📺 Log in
Settings → Network → Wi-Fi connection → QR code. - 📺 Use the app LG ThinQ on the phone for scanning.
For Android TV (For example, Sony Bravia or Xiaomi Mi TV):
- 📺 Go to
Settings → Network & Internet → Wi-Fi → Add network → QR code. - 📺 If your TV doesn't have a camera, generate a code on your smartphone and scan it using the manufacturer's app.
⚠️ Note: On some models Smart TV (especially budget ones) the QR code scanning function can only work through the proprietary app. For example, for Xiaomi TV will be required Mi Home, and for Philips — Philips TV Remote.
| Brand TV | QR code support | Required application |
|---|---|---|
| Samsung (Tizen) | Yes (since 2020) | SmartThings |

Security: Risks and How to Avoid Them
Connecting via QR code is convenient, but not without risks. The main threats are:
- 🕵️ Fake codes — Fraudsters can place their QR codes in public places (cafes, airports), redirecting you to phishing networks.
- 📡 Data leak — if the code is generated on a dubious website, it may contain malicious links.
- 🔓 Weak encryption - some generators create codes with outdated
WPAinstead ofWPA3.
How to protect yourself:
- 🛡️ Generate codes only from official sources — router web interface or verified services (
qi-fi.org). - 🛡️ Check the code format - it should start with
WIFI:T:WPA2;S:...orWIFI:T:WPA3;S:.... - 🛡️ Do not scan codes in public places — It’s better to check the network name and password with the administrator.
- 🛡️ Use two-factor authentication on the router, if supported.
If you suspect you have connected to a fraudulent network:
- Disconnect from it immediately in your device settings.
- Remove the network from saved (
Settings → Wi-Fi → [tap on the network] → Delete). - Check your device for viruses (for example, through Malwarebytes or Kaspersky).
Common mistakes and their solutions
Even with a QR code, connection can go wrong. Let's look at some common issues:
| Error | Possible cause | Solution |
|---|---|---|
| The QR code is not scanned. | Low code resolution or dirty screen | Wipe the camera and screen, increase the brightness |
| "Invalid code format" | The code is not generated in the WIFI standard: | Regenerate the code through the official source |
| The connection is interrupted | Weak signal or incompatible encryption | Move closer to the router or change the security type to WPA2 |
| "Network is saved, but there is no internet." | Problems on the provider or router side | Reboot your router and check your internet bill. |
| The QR code is not displayed in the router settings. | Outdated firmware or provider restrictions | Update your firmware or generate a code online |
If your device stubbornly refuses to connect, try:
- Reset network settings (
Settings → System → Reset → Reset Wi-Fi, mobile networks, and Bluetooth). - Regenerate the QR code with a different encryption type (for example, with
WPA3onWPA2). - Connect manually by entering the data from the code (they are visible when you enlarge the image).
⚠️ Note: On some devices (eg. Huawei With EMUI) After scanning the QR code, you may be asked to confirm via SMS or enter a CAPTCHA. This is normal—it's an additional security measure.
FAQ: Answers to frequently asked questions
Is it possible to connect a laptop to Wi-Fi via QR code?
Yes, but not all OS support it out of the box. Windows 11 you can use the app WiFi QR Connect from Microsoft StoreOn . macOS - scan the code via camera, then manually enter the data in the network settings. On Linux you will need to install the utility qrencode and manual addition of the network.
How to create a QR code for Wi-Fi without a router?
Use online generators:
- Go to the website
qifi.orgorqrcode.monster. - Enter the network name (SSID), password and encryption type.
- Download the generated code in PNG or SVG format.
Why does the QR code work on my phone but not on my TV?
Possible reasons:
- 📺 Your TV does not have a built-in camera for scanning (solution: use the manufacturer's app on your smartphone).
- 📺 The TV does not support the standard
WIFI:(solution: enter data manually). - 📺 Outdated firmware (solution: update TV software).
Check the compatibility of your model on the manufacturer's website.
Is it possible to change the Wi-Fi password without updating the QR code?
No. The QR code contains an encrypted password, so if you change it in the router settings, you'll have to generate a new code. The old code will become invalid, and devices will be unable to connect.
Is it safe to store Wi-Fi QR code in the cloud (Google Drive, iCloud)?
It can be stored, but with some reservations:
- 🔐 Upload code only in closed folders (not public links).
- 🔐 Use two-factor authentication for the cloud service.
- 🔐 Delete the code from the cloud if you no longer need it.
