Beaconing

nounStandard termTelecom & IT

The periodic transmission of small packets used to announce presence or signal network faults.

Beaconing is a continuous broadcast mechanism used by network devices to maintain timing, advertise capabilities, or report errors. In wireless networks, access points send beacon frames to announce their SSID and parameters to nearby clients. In older token-ring networks, a station initiates beaconing to alert the rest of the ring about a hard fault, helping to isolate a broken cable or failed node.

The access point is beaconing on channel 6, but it isn't accepting any client associations.
