  • A Wireless access point (WAP) is the base station that connects to the wired network. Most common configuration details for a WAP include:
    • Security Set Identifier (SSID): The name asigned to the WAP to identify itself to clients. The SSID may or may not be configured to broadcast its identity to all wireless clients.
    • 802.11 mode: The version of 802.11 in which the radio operates, such as 802.11n. Choices will be limited to the modes supported by the WAP hardware.
    • Security method: The method used to encrypt and restrict wireless client connections to the WAP.
