Chapter 3 Wireless LAN Network
Both WPA and WPA2 improve data encryption by using Temporal Key Integrity Protocol 
(TKIP), Message Integrity Check (MIC) and IEEE 802.1x. WPA and WPA2 use Advanced 
Encryption Standard (AES) in the Counter mode with Cipher block chaining Message 
authentication code Protocol (CCMP) to offer stronger encryption than TKIP.
If both an AP and the wireless clients support WPA2 and you have an external RADIUS 
server, use WPA2 for stronger data encryption. If you don't have an external RADIUS server, 
you should use WPA2-PSK (WPA2-Pre-Shared Key) that only requires a single (identical) 
password entered into each access point, wireless gateway and wireless client. As long as the 
passwords match, a wireless client will be granted access to a WLAN. 
If the AP or the wireless clients do not support WPA2, just use WPA or WPA-PSK depending 
on whether you have an external RADIUS server or not.
Select WEP only when the AP and/or wireless clients do not support WPA or WPA2. WEP is 
less secure than WPA or WPA2.
