Wi-Fi
Scan nearby networks and sample RSSI on this device.
On Field, choose Wi-Fi.
The phone lists networks it can see. You can sample the connected network or run a short survey. Samples save to the site about every two seconds while you record, or when RSSI jumps.
Allow Wi-Fi access when the system asks. If the radio is off, open system settings from the panel.
This is an on-device scan. It is not a design of the LAN. Diagnose observations on a survey are context. They are not a pass or fail.
