Claim:
1. A wireless communication terminal comprising: a processor coupled with a memory, the processor configured to execute: a roaming determining section configured to determining whether to perform a roaming in which access points are switched in the course of movement of the wireless communication terminal; a scanning section configured to, in a case where the roaming is performed to switch a connection to an access point in the course of movement of the wireless communication terminal, perform a scan for the access point from a high-priority scan-band in descending order; a roaming candidate selecting section configured to select an access point candidate for a roaming destination on the basis of information regarding the access points obtained from a scanning result of the scanning section; and a roaming executing section configured to, in a case where the access point for the roaming destination is found, perform a process of connecting to the access point of the roaming destination, wherein in a case where the scanning result of scanning a scan-band of a priority order indicates that the access point of the roaming destination is not found, the scanning section scans a scan-band of a lower priority order than the priority order, in a case where the roaming is performed, the scanning section scans, as the high-priority scan-band, a band that is the same as a band of a channel of an access point currently connected, and in a case where a result of the scanning indicates that the access point of the roaming destination is not found, the scanning section scans a band different from the band of the channel of the access point currently connected, and the bands scanned by the scanning section are an 802.1la band and an 802.1lb/g band.
