WPA (with RADIUS Server)
WPA (Wi-Fi Protected Access) provides dynamic key changes and 
constitutes the best security solution. This function requires that a 
RADIUS server is running on the network.
Figure 49   WPA (with RADIUS Server) Screen
1 Select WPA with RADIUS server from the Security Mode drop-down 
menu.
2 Select WPA mode from the drop-down menu, three modes are 
supported: WPA, WPA2, and Mixed mode.
3 Select Encryption technique from the drop-down menu, four options are 
available: TKIP, AES, Auto for WPA AES for WPA2, and AES for both WPA 
and WPA2. 
WPA supports TKIP and AES Encryption technique, for some old module 
of wireless client cards, they may only support TKIP. In this case, we 
suggest you to select “AUTO for WPA, AES for WPA2”. If your wireless 
client cards can support AES over WPA, we suggest you directly select 
“AES for both WPA and WPA2”. 
4 Enter the IP address of the RADIUS server on your network into the 
RADIUS Server field.
5 Enter the port number that the RADIUS server is operating on in the 
RADIUS Port field.
6 Enter the key for the RADIUS server in the RADIUS Key field.
7 By default, the WPA keys are changed every hour, but if you want to 
change this setting, you can do so by specifying the required time in the 
Re-key Interval field. 
8 Click Apply.
