ABSTRACT:
An object of the invention is to reduce the power consumption at the time of an automatic homing operation performed between a base station apparatus and a wireless LAN terminal apparatus. When an automatic homing operation is performed in which a scanning operation is repeated for searching an AP as a connection destination, the wireless LAN terminal apparatus10does not leave unchanged a scan pause time period which is a period of time between the previous scanning operation to the next scanning operation, but lengthens it as the number of scanning operations increases. More specifically, each time the scanning operation is repeated predetermined number n times, the wireless LAN terminal apparatus extends the scan pause time period by a given incremental value. The wireless LAN terminal apparatus has an upper limit value of the scan pause time period preliminarily set therein. Thus the scan pause time period is made not to exceed the upper limit value.
