To disable Wi-Fi access via QR code, you need to delete the file containing the QR code image. A QR code is simply machine-readable text represented visually.
Here's a breakdown of how to handle different scenarios:
Deleting the QR Code Image
- The most direct way to disable Wi-Fi sharing through a QR code is to delete the image file where the QR code is stored. This action prevents others from scanning the code and gaining network access.
Disabling WPS Functionality
If you are referring to the WPS button, which can generate a QR code for network access, the steps are different:
- Access your router's admin console: You'll typically do this by entering your router's IP address in a web browser. (For instance,
192.168.1.1
or192.168.0.1
). - Navigate to WPS settings: Look for sections labeled "WPS," "Wi-Fi Protected Setup," or similar terms in your router's settings.
- Disable WPS: Find the option to disable WPS and apply the changes. This action prevents the generation of QR codes through WPS.
Summary Table
Method | Description |
---|---|
Delete QR Code Image | Physically deleting the file where the QR code picture is stored disables sharing Wi-Fi via scanning this image. |
Disable WPS | If using the router's WPS feature (button), access the router's admin panel and disable WPS. This stops the router from generating new QR codes. |
Additional Points
- A QR code contains the network name (SSID) and password. Deleting the picture prevents the scanning and automatic connection.
- If the QR code is printed and is used to connect guests, you will have to make a new one, but you can disable WPS to prevent new ones from being generated.
