A wireless communication device is provided. The device is connectable to a first wireless network including an access point and a second wireless network including a terminal having an access point function. The device includes a setting section which stores setup data in a volatile storage area, a communication section which performs wireless communication using the setup data stored in the volatile storage area, and a determination section which determines which wireless networks the device is to be connected to. If the device is to be connected to the first wireless network, the setting section stores first setup data from the access point into the volatile storage area and a non-volatile storage area. If the device is to be connected to the second wireless network, the setting section stores second setup data from the terminal into the volatile storage area without storing it into the non-volatile storage area.
