Abstract: A method of connecting an access point (AP) device is provided. The method includes receiving media access control (MAC) address information of a terminal from the terminal through an external device, registering the received MAC address information, and determining whether the registered MAC address information corresponding to MAC address information registered to another AP device. In response to the registered MAC address information corresponding to the MAC address information registered to the other AP device, an AP device managing the registered MAC address information is determined among the AP device and the other AP device. A connection request is received from the terminal, and the terminal is connected to the AP device based on whether MAC address information of the connection request is corresponding to the registered MAC address information.
