Abstract:
1. A wireless LAN connection method for a wireless LAN terminal apparatus searching a base station apparatus of a connection destination comprising, performing an automatic homing operation in which the wireless LAN terminal apparatus repeats a scanning operation wherein the wireless LAN terminal apparatus transmits a probe request to homing destination access points to attempt to find one of the homing destination access points that answers the probe request with a probe response received by the wireless LAN terminal apparatus and is the base station apparatus of connection destination; lengthening a scan pause time period as the number of scanning operations increases where the scan pause time period is defined as a period of time from the previous scanning operation to the next scanning operation; when service set identifiers (SSIDs) and priorities are specified for the homing destination access points, establishing a selection order of the homing destination access points that answer the probe request with SSIDs indicating that they are the base station apparatus of a connection destination by first selecting the homing destination access point having the highest priority and second, when the priorities of the homing destination access points are the same, selecting the homing destination access point with a highest radio field intensity; and when SSIDs are not specified for the homing destination access points, establishing a selection order of the homing destination access points that answer the probe request by selecting the homing destination access point with the highest radio field intensity.
