Disclosed is a system and method for performing a fast channel scan so as to minimize the communication disruption period ( 10 ) which occurs during a handoff of a mobile station (STA) ( 20 - 23 ) in a wireless local area network (WLAN) ( 100 ). Each mobile station (STA) includes an associated nearest-neighbor table identifying nearest-neighbor APs ( 14 - 16 ) in the network to the AP with which the STA is currently associated. When a STA ( 20 - 23 ) performs a handoff, its nearest-neighbor table is used to perform a prioritized search of those channels of operation included in the table belonging to nearest-neighbor APs ( 14 - 16 ). In this manner, by prioritizing the search to first search the channels of operation belonging to nearest-neighbor APs ( 14 - 16 ), there is a greater likelihood of locating a candidate ap ( 14 - 16 ) to form an association with in less time as compared with the prior art search method of blindly searching each and every operating channel in the network.
