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

There are several ways to obtain a QR code for connecting to Wi-Fi. The most secure is to generate one directly on the router or in the provider's mobile app. Here are all the options:

• 🔄 From the router: Most modern routers (TP-Link, Keenetic, ASUS) display the QR code on the sticker below or in the web interface (section Wi-Fi → Security Settings).
• 📱 Through the provider's application: U Rostelecom, Beeline or MTS In your personal account, there is a section called "My Wi-Fi Network" with the option to generate a code.
• 💻 Using online generators: Services like QR Code Generator or qi-fi.org Allows you to generate a code using your network name and password. Important: Use only trusted websites!
• 📲 From another connected device: On iPhone or another Android You can generate a code in the Wi-Fi settings (section "Share password").

If you are a network administrator, we recommend using the first or second method—they guarantee the accuracy of the data. Online generators may produce invalid codes if the encryption type is specified incorrectly (WPA2/WPA3) or the case of characters in the password.

⚠️ Attention: On phones Samsung With Android 14 A bug may occur where the QR scanner cannot see codes from routers. Xiaomi or HuaweiIn this case, use Google Lens or update the firmware via Settings → Software Update.

How to create your own QR code for a guest network?

If you want to provide Wi-Fi access to guests without disclosing the password, generate a separate QR code for them. Here's how:

Method 1: Through the router settings

Most modern routers allow you to create a guest network with a separate password and QR code:

1. Go to the router's web interface (usually at 192.168.0.1 or 192.168.1.1).

4. Save the settings - the router will generate a QR code automatically.

Method 2: Using an online generator

Use services like qi-fi.org:

1. Select the security type (WPA2-PSK or WPA3).

2. Enter the network name (SSID) and password.

3. Click Generate — download the QR code in PNG format.

For guest network security:

• 🔒 Set a complex password (at least 12 characters with numbers and symbols).
• 🕒 Limit the network time (for example, 6 hours).
• 📶 Disable access to local devices (optional) AP Isolation in the router).

Security: Risks of connecting via QR code

While QR codes are convenient, they're not without risks. Here's what to watch out for:

• 🕵️ Fake codesAttackers may place QR codes in public places (cafes, airports) that lead to phishing pages. Always verify the source of the code.
• 🔄 Network data leakIf you share a QR code, anyone with it will be able to connect to your network. It's best to use a separate guest network for guests.
• 📡 Traffic interceptionOn open networks (without a password), data is transmitted unencrypted. Avoid connecting to such networks via QR codes.

How to minimize risks:

• 🛡️ Use only codes from trusted sources (router, official applications).
• 🔄 Change your main network password regularly (every 3-6 months).
• 📵 Disable automatic connection to open networks in settings Samsung (Settings → Connections → Wi-Fi → Advanced → Smart connection).

If you connect to a public network via QR (for example, in a hotel or restaurant), forget it after use:

1. Open Settings → Wi-Fi.

2. Tap on the network name and select Forget.

⚠️ Attention: On Android 13+ there is a function "Suspicious Network Notification", which warns you if the network is offline or has a suspicious certificate. Don't ignore these warnings!
