Leo clicks the Ok button to save the 802.1x EAP settings.
Leo then clicks the WPA2-CCMP Settings button. WPA2 constantly changes keys, but requires an initial
key, known to both ends of the communication. If Leo was not using 802.1X EAP user authentication, that
initial key would need to be entered here, in the Key Settings section. However, with 802.1x EAP, the RADIUS
server supplies the initial key, so that Key Settings section is grayed out for Leo.
Leo does need to set the frequency with which the key for broadcast communication is changed. By default,
the WS2000 changes the broadcast every 84,600 seconds, i.e., every twenty-four hours. Breaking WEP
encryption requires several hours of solid traffic, so Leo decides to change the broadcast key rotation to 3600
seconds, or once an hour.
