In IEEE 802.11, two-way communication is used to authenticate an open system. In order to authenticate the client, the server must give the station ID (typically the MAC address). Response to the client's previous request is either a successful or failed authentication response from the access point/router. An error may arise if, for example, an AP/router configuration does not include the client's MAC address. In what ways is it advantageous to use this kind of authentication scheme? In what ways does this authentication technique have security vulnerabilities that might be mitigated?
