When configuring a wireless LAN using a graphical user interface, which security mode requires clients to authenticate using a shared passphrase set by the administrator?
Personal mode requires clients to authenticate using a pre-shared key (PSK), which is a shared passphrase set by the administrator. This mode is suitable for networks without a Remote Authentication Dial-In User Service (RADIUS) server. Enterprise mode requires a RADIUS server to authenticate clients using individual credentials. Open authentication allows clients to connect without any credentials, and MAC address filtering restricts access based on device MAC addresses.
