A computing system for recovery of lost access points in a distributed wireless local area network, including: (a) a host controller, (b) a plurality of access point, and (c) a plurality of stations. When setting up the network, the host controller is configured to register the plurality of access points, instruct the access points to send beacons to the plurality of stations, and perform a handshake to generate a unique encryption key for each of the plurality of stations. When the host controller detects that a physical access point has been lost and then recovered, it can optionally perform a handshake to generate a new encryption key and transmit this new encryption key to the other access points in the network before data communication commences to any of the stations through the recovered physical access point.
