Configuration | Security | Wireless Security | Wi-Fi Protected Access (WPA)
Wi-Fi Protected Access provides a higher level of protection for wireless LAN client stations as it
includes methods for mutual authentication, strong encryption, and data integrity. WPA takes the
original master key only as a starting point and derives its encryption keys dynamically from this
master key. WPA regularly changes and rotates the encryption keys so that the same encryption key
is never used twice. Key exchange is done automatically transparent to the user.
To enable the WPA security for your WLAN you need:
 An access point that has WPA support like the Gemtek Systems P-520r
 A wireless network card with WPA ready driver
 A supplicant that supports WPA (e.g. Windows XP client)
To configure the WPA with pre-shared key security on the P-520r use the Configuration | Security |
Wireless Security| Wi-Fi Protected Access (WPA) menu, select the WPA with pre-shared key
security method and enter the shared secret:
