Abstract: A method of wireless security setup is introduced. The method includes a station transmitting a first packet containing a first SSID and related information; an access point transmitting a second packet containing the first SSID to inform that the connection between the station and the first SSID is built; the station transmitting a third packet by the connection with the first SSID to ask for an SSID other than the first SSID and related information; the access point transmitting a fourth packet containing a second SSID and the related information using the first SSID in response to the third packet; the station transmitting a fifth packet containing the second SSID and the related security information; and the access point transmitting a sixth packet containing the second SSID to inform the station that the connection between the station and the second SSID is built.
