Background Scanning

Scanning intervals can be configured on the 2.4 GHz and 5 GHz radios independently.
Note: If you want to disable Background Scanning, clear the check box; this should result in a minor increase in AP performance, but removes the detection of rogue APs. You can also decrease the scan frequency, as less frequent scanning improves overall AP performance.
Note: You can also disable Background Scanning on a per-WLAN basis from the Dashboard > WiFi Networks screen. To disable scanning for a particular WLAN, click the Edit link next to the WLAN for which you want to disable scanning, open Advanced Options, select the Radio Control tab, and click the check box next to Disable Background Scanning.
