Radius Server 2 IP and Port: Enter the IP address and port number for your secondary 
RADIUS server, if you have one. 

Radius Server 2 Secret: Enter the password for access to Radius Server 

Click Apply in the top right corner to apply your WPA settings.

Like WPA, WPA2 supports two protocols for storing and generating keys:

Pre-Shared Key (PSK): PSK allows WPA2 to generate keys from a pre-shared passphrase 
that you configure. The keys are updated periodically based on time or number of packets. 
Use PSK in smaller deployments where you do not have a RADIUS server. 

Extensible Authentication Protocol (EAP): EAP allows WPA to synchronize keys with an 
external RADIUS server. The keys are updated periodically based on time or number of 
packets. Use EAP in larger, enterprise-like deployments where you have an existing 
RADIUS framework. 

WPA2 PSK / WPA2 EAP: There are optional AUTO modes for each WPA2 protocol. WPA2 
EAP AUTO and WPA2 PSK AUTO try to connect using WPA2 security, and will default back 
to WPA if the client is not WPA2 capable.

WPA2 support is only available in Access Point Mode. WPA support is not available in 
Bridge Mode.

Encryption Mode: In the Authentication Type field, select WPA2-PSK. 

WPA Settings: 

Cypher Type: select AES. Advanced Encryption Standard (AES) is an advanced block 
cipher protocol for enforcing key integrity. 

Group Key Update: Specifies when the SonicWALL Secure Anti-Virus Router 80 Wireless 
updates the key. Select By Timeout to generate a new group key after an interval specified 
in seconds. Select By Packet to generate a new group key after a specific number of 
packets. Select Disabled to use a static key. 

Interval: If you selected By Timeout, enter the number of seconds before WPA2 
automatically generates a new group key.
