ABSTRACT:
A control unit of a wireless connection terminal compares the received signal strength indicator of an access point currently connected to by the wireless connection terminal with the received signal strength indicator of a neighboring access point. If the difference between the two received signal strength indicators is higher than or equal to 40%, the connection to the current access point is severed and roaming in which the connection is switched to the neighboring access point is performed. Even when the difference between the two received signal strength indicators is not higher than or equal to 40%, roaming in which the connection is switched to the neighboring access point is performed if the received signal strength indicator of the access point to which the wireless connection terminal is currently connected becomes lower than or equal to 20%.
