WPA (Wi-Fi Protected Access)/WPA2:
It must be used in connection with an authentication server such as RADIUS to provide
centralized access control and management. It can provide stronger encryption and
authentication solution than none WPA modes. WPA2 is the second generation of WPA security.
There are two types for choose AES and TKIP+AES.
TKIP (Temporal Key Integrity Protocol): Takes the original master key only as a starting point and
derives its encryption keys mathematically from this mater key. Then it regularly changes and
rotates the encryption keys so that the same encryption key will never be used twice.
AES (Advanced Encryption Standard): This Provides security between client workstations
operating in ad hoc mode. It uses a mathematical ciphering algorithm that employs variable key
sizes of 128, 192 or 256 bits.
RADIUS (Remote Authentication Dial In User Service) Server:
a protocol for carrying authentication, authorization, and configuration information between a
Network Access Server which desires to authenticate its links and a shared Authentication Server.
Please key in the IP Address for the RADIUS Server.
RADIUS (Remote Authentication Dial In User Service) Port:
Besides the IP address of the RADIUS Server, you have to enter the port number for the server.
Port 1812 is the reserved RADIUS-authentication port described in RFC 2138. Earlier AP (RADIUS
clients) use port 1945. The default value will be shown on this box. You can keep and use it.
RADIUS (Remote Authentication Dial In User Service) Key:
A RADIUS Key is like a password, which is used between IAS and the specific RADIUS client to
verify identity. Both IAS and the RADIUS client must be use the same RADIUS Key for successful
communication to occur. Enter the RADIUS Key.
Group Key Rotation Interval:
Key in the time for the WAP group key rotation interval. The unit is second. With increasing rekey
interval, user bandwidth requirement is reduced
WPA/WPA2 Re-auth Interval:
When a wireless client has associated with the Wireless Voice Gateway 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 3600, you may modify it
WPA-PSK (WPA-Pre-Shared Key) /WPA2-PSK:
Its useful for small places without authentication servers such as the network at home. It allows
the use of manually-entered keys or passwords and is designed to be easily set up for home
users.
Please type the key to be between 8 and 63 characters, or 64 hexadecimal digits. Only the
devices with a matching key that you set here can join this network.
WEP (Wired Equivalent Privacy) Encryption:
There are two types encryption to choose 64-bit or 128-bit. If you choose Disabled, the Network
