Abstract: A WAP including: a non-volatile memory, an event detection circuit and a rule initiation circuit. The non-volatile memory stores network event rules each of which tags a station to monitor and actions to initiate for a targeted device if the tagged station undergoes a network event. The event detection circuit monitors each wireless station for a transition in communication status corresponding to a network event, and identifies the wireless station and the network event. The rule initiation circuit determines whether the identified station and network event corresponds with one of the network event rules for the identified station in the non-volatile memory, and in the event of a match, initiates the action prescribed for the corresponding targeted device.
