4.4.3 Introduction to WPA
Wi-Fi Protected Access (WPA) is a subset of the IEEE 802.11i standard. WPA is preferred to
WEP as WPA has user authentication and improved data encryption. See the appendix for
more information on WPA user authentication and WPA encryption.
If both an AP and the wireless clients support WPA and you have an external RADIUS server,
use WPA for stronger data encryption. If you don't have an external RADIUS server, you
should use WPA-PSK (WPA-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.
4.4.4 WPA-PSK Application Example
A WPA-PSK application looks as follows.
1 First enter identical passwords into the AP and all wireless clients. The Pre-Shared Key
(PSK) must consist of between 8 and 63 ASCII characters (including spaces and
symbols).
2 The AP checks each wireless client's password and (only) allows it to join the network if
the password matches.
3 The AP derives and distributes keys to the wireless clients.
4 The AP and wireless clients use the TKIP encryption process to encrypt data exchanged
between them.
Key 1 to Key 4 The WEP keys are used to encrypt data. Both the Prestige and the wireless stations
must use the same WEP key for data transmission.
If you chose 64-bit WEP, then enter any 5 ASCII characters or 10 hexadecimal
characters ("0-9", "A-F").
If you chose 128-bit WEP, then enter 13 ASCII characters or 26 hexadecimal
characters ("0-9", "A-F").
You must configure at least one key, only one key can be activated at any one time.
The default key is key 1.
