Rogue AP detection allows an AP to scan for nearby WiFi signals. Of
course, single-band 2.4GHz APs can only scan for 2.4GHz WiFi signals while
dual-band APs can scan for both 2.4GHz and 5GHz WiFi signals.

 

If Rogue AP cannot be initiated, go to Wireless Services under Device
Management and enabled the Background Scanning option for the
appropriate band.
