1. An access point that connects to terminals to network through a wireless LAN connection device equipped on said terminals, said access point comprising:

  • an operation receiving unit that receives a prescribed operation;

    a detection unit that detects a status of a connection configuration required for connection to the network, when said prescribed operation is received by said operation receiving unit;

    a mode activation unit that, when the detected status of the connection configuration indicates that the connection configuration remain to be performed, activates a restricted receiving mode in which only a packet including information specific to one of said terminals is accepted as an initial configuration packet;

    a terminal identification unit that, when said initial configuration packet sent from a first terminal among said terminals is received while the restricted receiving mode is active, identifies the first terminal that sent the initial configuration packet based on said terminal-specific information;

    an encryption key setting unit that, prior to the commencement of subsequent communications with said first terminal identified by said terminal identification unit, sets a first encryption key to be used for communications with said first terminal to a value corresponding to an encryption key set in said first terminal, using said terminal-specific information; and

    a communication unit that performs wireless communication with said first terminal while decoding wireless communication data using said first encryption key.
