When using WiFi Scanner, if you only see one SSID when you have multiple Access Points broadcasting it across your network, you may have the Show Best SSID for Scan Results checked in the Preferences.

When using WiFi Scanner, if you only see one SSID when you have multiple Access Points broadcasting it across your network, you may have the Show Best SSID for Scan Results checked in the Preferences.

To view all the SSIDs, simply uncheck this option in Preferences.
