For WPA-2; Mixed WPA2/WPA 
Wireless Security:   
The WPA2 is suitable for enterprises. 
It must be used in conjunction with an 
authentication server such as RADIUS 
to provide centralized access control 
and management. It can provide 
stronger encryption and authentication 
solution than other WPA mode. 
Data Encryption:
   
Select the encryption type for the 
WPA2 mode. There are three types 
that you can choose, TKIP, AES, 
TKIP+AES
. (For detailed information 
please refer to WPA section.)
 
WPA2 Pre-authentication:   
The wireless client that has associated 
with one AP (router A) can do the 
authentication with another AP (router 
B) in advance. If the client roams to 
AP (B), it can associate with AP (B) 
quickly. Please click Enabled to 
activate this function. 
Network Re-auth Interval:   
When a wireless client has associated 
with the AP for a period of time longer 
than the setting here, it would be 
disconnected and the authentication 
will be executed again. The default 
value is 36000, you may modify it. 
WPA Group Rekey Interval:  
Enter the time for the WPA group 
rekey interval. The unit is second. With 
increasing rekey interval, user 
bandwidth requirement is reduced.   
RADIUS Server IP Address, RADIUS 
UDP Port, 
and RADIUS Shared 
Secret:  
Please refer to the elucidation in the 
previous 802.1x section. 
When the settings are finished, click
