Key Management 

Protocol

Choose WPA in this field.

WPA Mixed Mode

The Prestige can operate in WPA Mixed Mode, which supports both clients 

running WPA and clients running dynamic WEP key exchange with 802.1x in the 

same Wi-Fi network.
Select the check box to activate WPA mixed mode. Otherwise, clear the check 

box and configure the Group Data Privacy field.

Group Data Privacy Group Data Privacy allows you to choose TKIP (recommended) or WEP for 

broadcast and multicast ("group") traffic if the Key Management Protocol is 

WPA and WPA Mixed Mode is disabled. WEP is used automatically if you have 

enabled WPA Mixed Mode. 
All unicast traffic is automatically encrypted by TKIP when WPA or WPA-PSK 

Key Management Protocol is selected.

WPA Group Key 

Update Timer

The WPA Group Key Update Timer is the rate at which the AP (if using WPA-

PSK key management) or RADIUS server (if using WPA key management) 

sends a new group key out to all clients. The re-keying process is the WPA 

equivalent of automatically changing the WEP key for an AP and all stations in a 

WLAN on a periodic basis. Setting of the WPA Group Key Update Timer is also 

supported in WPA-PSK mode. The Prestige default is 1800 seconds (30 

minutes). 

Authentication 

Databases

When you configure Key Management Protocol to WPA, the Authentication 

Databases must be RADIUS Only. You can only use the Local User Database 

Only with 802.1x Key Management Protocol.
