Connecting to Wi-Fi via QR code — This is one of the fastest and most convenient ways to connect a device to a wireless network without having to manually enter complex passwords. This method is especially relevant for Smart TV, smartphones with awkward keyboards, or guest networks where you don't want to share your password. But how exactly does this technology work, and why isn't it always available?
In this article we will look at all possible connection methods via QR code, including hidden router features, built-in operating system tools, and third-party apps. You'll learn how to generate a code for your network, which devices support this feature out of the box, and what to do if scanning isn't working. You'll also learn how to bypass restrictions on some router and TV models.
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 the network data, including its name (SSID), encryption type (WPA2, WPA3) and a password. When scanning this code, the device automatically extracts the information and offers to connect without manual entry.
The code format is standardized: it contains a line of the following type:
WIFI:T:WPA;S:mynetwork;P:mypassword;;
Where:
- 🔹
T— encryption type (WPA,WEP,nopassfor open networks) - 🔹
S— network name (SSID) - 🔹
P- password - 🔹
H- hidden network (optional, valuetrue/false)
This code can be generated on a router, in a provider's mobile app, or using online services. The main advantage is eliminating input errors, which is especially important for complex passwords with symbols !@#$%.
Which devices support QR code connection?
Not all gadgets can read Wi-Fi QR codes out of the box. Here's the current list of devices with native support (as of 2026):
| Device type | QR support | Notes |
|---|---|---|
| Android 10+ | ✅ Yes | Via Quick Settings or the camera |
| iPhone (iOS 11+) | ✅ Yes | Only via the Camera app |
| Smart TV (Samsung, LG, Sony) | ⚠️ Partially | 2020 and newer models only |
| Windows 11 | ❌ No | Third-party applications are required |
| Routers (TP-Link, ASUS, Keenetic) | ✅ Yes | Generating code in the web interface |
On Android And iOS The function works stably, but with Smart TV problems often arise: some models (for example, Xiaomi TV (older than 2021) do not support direct scanning. In such cases, a workaround using a smartphone will help.
⚠️ Attention: On routers from providers (for example, Rostelecom or MTS) QR code generation may be disabled in the firmware. Check for the option in the section Wi-Fi → Guest Network.
How to generate a QR code for your Wi-Fi network
There are three main ways to create a QR code for connection:
-
Via the router's web interface
Go to your router's control panel (usually at
192.168.0.1or192.168.1.1), find the sectionWi-Fi → QR codeand download the image. On Keenetic it looks like this:Main menu → Wi-Fi network → QR icon next to the network name -
Using mobile applications
Provider Applications (MTS Connect, Beeline Dom) or universal utilities like WiFi QR Generator allow you to create a code even if the router does not support this function.
-
Online services
Sites like
qifi.orgorqrstuff.comgenerate a code based on the entered data. Important: do not use such services for corporate networks — there is a risk of password leakage.
Make sure your router is turned on and distributing Wi-Fi.
The network password does not contain Cyrillic characters (it may not display correctly in the code)
The device you are generating the code from is connected to the same network.
Save the code to the cloud (Google Drive, iCloud) in case of loss-->
If you are generating a code for a guest network, make sure the option is enabled in your router settings. Allow connection via QR (on ASUS this can be called QR Code Share).
Step-by-step instructions: connecting via QR code on Android
On smartphones with Android 10 and newer the process is simplified as much as possible:
- Open Settings → Wi-Fi.
- Tap on the icon QR code (usually in the upper right corner).
- Point the camera at the code. The device will automatically connect to the network.
On some firmware (for example, MIUI on Xiaomi) another way:
Settings → Connections → Wi-Fi → Advanced → Connect via QR code
If scanning does not work:
- 📱 Check app permissions "Camera" (must have permission to access Wi-Fi).
- 🔄 Restart your smartphone.
- 🛠️ Update the firmware (on Samsung This may solve the problem with reading codes).
Connecting via QR code on iPhone (iOS) and Mac
On iPhone With iOS 11 and newer scanning works through the standard application "Camera":
- Open "Camera" and point at the QR code.
- A notification will appear Connect to a Wi-Fi network - tap on it.
- Confirm the connection (you do not need to enter a password).
On Mac (macOS Ventura and later) The process is similar, but requires using an app "Camera" (not to be confused with "Photo"):
Launchpad → Camera → Point to QR → Click on notification
⚠️ Attention: If the QR code is generated for a network withWPA3, and yours iPhone older than the model iPhone 6s, the connection may not work. In this case, change the encryption type on the router toWPA2.
Connecting Smart TV to Wi-Fi via QR code
The situation with televisions is more complicated: only modern models (Samsung QLED 2022+, LG OLED C2 and newer, Sony Bravia XR) support direct scanning. Instructions for Samsung Tizen:
- Open “Settings” → “General” → “Network” → “Open network”.
- Select Connect via QR code.
- Point your TV camera at the code (an external webcam may be required for older models).
For TVs without QR support, there is a workaround:
- 📱 Take a photo of the code with your smartphone.
- 🖥️ Send photos to your TV via Google Cast or AirPlay.
- 🔍 Use the app TV Remote (for example, for LG) for manual data entry from the code.
Why doesn't the TV see the QR code?
Most Smart TVs have low-resolution cameras and struggle to focus on small images. Try this:
- Increase the code on the smartphone/tablet screen.
- Print the code on paper (size not less than 10×10 cm).
- Use an external USB camera (supported on Android TV).
Connecting Windows and other devices
Windows 11 It doesn't support QR code connection natively, but there are two working methods:
-
Via Camera app + PowerShell
Scan the standard code "With a camera", then execute in PowerShell:
netsh wlan connect name="NETWORK_NAME" ssid="NETWORK_NAME"(take the data from the QR code decoder using an online decoder).
-
Third-party utilities
Programs like WiFi QR Connect or QR WiFi automate the process. Download them from Microsoft Store.
For Linux (Ubuntu, Fedora) the utility will do zbar-tools:
sudo apt install zbar-tools
zbarimg --raw qrcode.png | awk -F';' '{print "nmcli dev wifi connect "$2" password "$4}' | bash
⚠️ Attention: On corporate laptops with Windows access may be blocked netsh via Group Policy. In this case, please contact your network administrator.
Common problems and their solutions
If the QR code connection does not work, check:
| Problem | Cause | Solution |
|---|---|---|
| The QR code is not scanned. | Low code resolution | Enlarge the code on the screen or print it out |
| Authentication error | Incorrect password in the code | Generate the code again |
| The notification does not appear | Notifications for the Camera are disabled | Check your notification settings |
| The TV does not support QR | Outdated firmware | Update your software or use your smartphone as an intermediary |
If your router doesn't generate a QR code, try:
- 🔧 Reset your router to factory settings (
Resetbutton for 10 seconds). - 📥 Update firmware via the web interface.
- 📱 Use the provider's mobile app instead of the web panel.
FAQ: Answers to frequently asked questions
Is it possible to connect to Wi-Fi using a QR code without a camera?
Yes, if you have a file with code (eg. qrcode.png). On Android You can open it in the gallery and tap on the notification. Windows use programs like QR Code Desktop Reader.
Is it safe to generate Wi-Fi QR codes on third-party websites?
The risk is minimal if the site does not store the entered data. However, for corporate networks, it is better to use local generators (for example, the app WiFi QR Generator For Android).
Why doesn't my iPhone connect to the network after scanning a QR code?
Most often, this is due to incompatible encryption types. Try changing the encryption type on your router. WPA3 on WPA2 or check if the MAC address filter is enabled.
How to connect a printer using a QR code?
Most modern printers (HP, Canon) support connection via WPS or native applications (eg HP Smart). The QR code for them is generated in the manufacturer's mobile application.
Is it possible to create a QR code for a hidden Wi-Fi network?
Yes, there must be a parameter in the code H:true. Example line:
WIFI:T:WPA;S:myhidden;P:mypass;H:true;;
But not all devices support connecting to hidden networks via QR.
