The WPA2 security mode is currently the most robust form of encryption for wireless networks. It 
requires a RADIUS server to authenticate user credentials and is a full implementation the security 
protocol. Use this security option for maximum protection of your network. However, it is the least 
backwards compatible with older devices.

The WPA security mode is a security subset of WPA2. It requires the presence of a RADIUS server 
on your network in order to validate user credentials. This encryption standard is slightly older than 
WPA2 and therefore is more compatible with older devices.

Click Network Settings > Wireless to display the General screen. Select More Secure as the 
security level. Then select WPA or WPA2 from the Security Mode list.

Wireless > General: More Secure: WPA(2)

Group Key Update 
Timer

The Group Key Update Timer is the rate at which the RADIUS server sends a new 
group key out to all clients. 

Encryption

If the security mode is WPA-PSK, the encryption mode is set to TKIP to enable 
Temporal Key Integrity Protocol (TKIP) security on your wireless network. 

If the security mode is WPA-PSK2 and WPA-PSK Compatible is disabled, the 
encryption mode is set to  AES to enable Advanced Encryption System (AES) security 
on your wireless network. AES provides superior security to TKIP.

If the security mode is WPA-PSK2 and WPA-PSK Compatible is enabled, the 
encryption mode is set to TKIPAES MIX to allow both TKIP and AES types of security 
in your wireless network.
