WPA-PSK: Clients using WPA with a Pre-shared Key are accepted for authentication.   
    WPA2-PSK: Clients using WPA2 with a Pre-shared Key are accepted for authentication. 
  WPAPSKWPA2PSK: Clients using WPA or WPA2 with a Pre-shared Key are accepted 
for authentication. 
    WPA Algorithms: Selects the data encryption type to use. 
  TKIP: Uses Temporal Key Integrity Protocol (TKIP) keys for encryption. WPA specifies     
TKIP as the data encryption method to replace WEP. TKIP avoids the problems of 
WEP static keys by dynamically changing data encryption keys. 
  AES: Uses Advanced Encryption Standard (AES) keys for encryption. WPA2 uses AES 
Counter-Mode  encryption  with  Cipher  Block  Chaining  Message  Authentication 
Code  (CBC-MAC)  for  message  integrity.  The  AES  Counter-Mode/CBCMAC 
Protocol (AESCCMP) provides extremely robust data confidentiality using a 128 bit 
key.  Use  of  AES-CCMP  encryption  is  specified  as  a  standard  requirement  for 
WPA2.  Before  implementing  WPA2  in  the  network,  be  sure  client  devices  are 
upgraded to WPA2-compliant hardware. 
  TKIP/AES: Uses either TKIP or AES keys for encryption. WPA and WPA2 mixed modes 
allow both WPA and WPA2 clients to associate to a common SSID. In mixed mode, 
the unicast encryption type (TKIP or AES) is negotiated for each client. 
    Pass phrase: Enter a pass phrase encryption key format.   
  Key Renewal Interval: Sets the time period for automatically changing data encryption 
keys and                redistributing them to all connected clients. (Default: 3600 seconds) 
  Access Policy: The access policy can be set to allow or reject specific station MAC addresses. 
  Add a station MAC: Enter the MAC address of the station that you want to filter.
