Wi-Fi Protected Access in Mixed Mode Deployment 
In a large network with many clients, a likely scenario is that access points will be upgraded before all the 
Wi-Fi clients. Some access points may operate in a mixed mode, which supports both clients running 
Wi-Fi Protected Access and clients running original WEP security. While useful for transition, the net effect 
of supporting both types of...
