1. Confirm the network details
Check the SSID (network name), password and security mode in your router settings. A mismatch in any of these can prevent a phone from joining.
If your router supports a guest network, consider sharing that instead of a network used by staff or personal devices.
2. Generate the code and test it on a new device
Choose WiFi in the AIQRGO tool, enter the exact network name and select the matching security option. Choose no password only when the network is genuinely open.
Test the code with a device that has not already joined the network. A saved connection can hide incorrect QR details.
3. Share it only with the intended guests
Anyone who can scan a password-protected WiFi code may be able to use the network. Place signs where intended guests can see them; rotate the guest password if you need to revoke access.
Avoid publicly displaying a code for a private or hidden network unless you understand who can access and reuse the information.
If a phone cannot connect
Recheck the network name, security mode and password. Confirm the phone supports WiFi QR codes and that the router allows the device to join.
