DESCRIPTION
Security Mode
Choose WPA-PSK or WPA2-PSK from the drop-down list box.
WPA Compatible
This check box is available only when you select WPA2-PSK or WPA2 in the 
Security Mode field.
Select the check box to have both WPA2 and WPA wireless clients be able to 
communicate with the P-660HWP-Dx even when the P-660HWP-Dx is using 
WPA2-PSK or WPA2.
Pre-Shared Key 
The encryption mechanisms used for WPA/WPA2 and WPA-PSK/WPA2-PSK 
are the same. The only difference between the two is that WPA-PSK/WPA2-PSK 
uses a simple common password, instead of user-specific credentials.
Type a pre-shared key from 8 to 63 case-sensitive English keyboard characters 
(including spaces and symbols).
ReAuthentication 
Timer (In 
Seconds)
Specify how often wireless clients have to resend usernames and passwords in 
order to stay connected. Enter a time interval between 10 and 9999 seconds. The 
default time interval is 1800 seconds (30 minutes). 
Note: If wireless client authentication is done using a RADIUS 
server, the reauthentication timer on the RADIUS server 
has priority.
Idle Timeout (In 
Seconds)
The P-660HWP-Dx automatically disconnects a wireless station from the wireless 
network after a period of inactivity. The wireless station needs to send the 
username and password again before it can use the wireless network again.
 
Some wireless clients may prompt users for a username and password; other 
clients may use saved login credentials. In either case, there is usually a short 
delay while the wireless client logs in to the wireless network again.
This value is usually smaller when the wireless network is keeping track of how 
much time each wireless station is connected to the wireless network (for 
example, using an authentication server). If the wireless network is not keeping 
track of this information, you can usually set this value higher to reduce the 
number of delays caused by logging in again.
