Abstract

After the end of the Wi-Fi Direct Connection, it is necessary to perform a resetting control by the user to reuse the network that was used before the Wi-Fi Direct Connection. A wireless communication device includes a memory unit that stores a communication setting information, and a communication control unit that controls a wireless communication in accordance with the communication setting information. When the first wireless communication switches to the second wireless communication, the communication control unit stores the communication setting information of the first wireless communication and ends the first wireless communication. After that, when the second wireless communication is turned off, the communication control unit controls the first wireless communication in accordance with the communication setting information of the first wireless communication.
