A Wi-Fi QR code helps guests join a network without copying a long password. It is useful at a reception desk, in a meeting room or in a guesthouse. The code contains network credentials, so treat the printed image as another way of sharing access to that network.
Check the network you want to share
Choose the guest network rather than an internal network used by staff or business equipment. Copy the network name exactly, including spaces and capital letters. Check the security mode in your router settings; the generator supports WPA/WPA2, WEP and open networks.
A QR code does not change the router’s security. WEP is supported for compatibility with existing networks, rather than as a recommendation for a new setup. If access also requires a browser login or captive portal, the guest may still need to complete that step after joining.
Enter the details and generate
Select Wi-Fi in the QR generator. Add the network name, choose the matching security mode and enter the password if the network is secured. Select Hidden network only if the router hides that network. Click Generate QR Code and choose PNG or SVG.
The generator escapes punctuation in the name and password before encoding the WIFI payload. Do not replace punctuation yourself: enter the real credentials. Open networks do not encode a password. Processing happens in your browser; the network name and password are not sent to Ternyxa.
Test with a device that is not already connected
Use another phone, or a device that does not have the credentials saved. Scan the image and check that it offers the intended network. Confirm the connection and test internet access. Device camera apps and network features vary, so test the phones your guests commonly use.
For printing, preserve the quiet border and use a dark code on a light background. Scan a real proof at its final size and viewing distance. Avoid a glossy surface or a position where furniture, folds or another graphic can obscure part of the code.
