Description
WPA Mode
Lets administrators select the WPA mode they want to use. Choices are:
•
WPA-PSK = select this setting if your access points and wireless clients support WPA-Pre-Shared
Key (PSK) Authentication.
•
WPA2-PSK = select this setting if your access points and wireless clients support WPA2-PSK
Authentication.
•
Auto (WPA-PSK or PWA2-PSK) = select this setting if your access points and wireless clients
support either WPA-PSK or WPA2-PSK. (
default
)
Cipher type
Algorithm encryption to be used. Choices are:
•
TKIP = automatic encryption with WPA-PSK; requires pre-shared key.
•
AES = automatic encryption with WPA2-PSK; requires pre-shared key.
•
TKIP and AES = uses both TKIP and AES cipher types; requires pre-shared key. (
default
)
Group Key Update Interval
Number of seconds that instructs the Gateway how often it should change the encryption keys.
Usually the security level is higher if you set the period shorter to change encryption keys more often.
Default value is 3600 seconds (6 minutes). Type 0 to disable group key update interval.
Pre-shared Key
Shared secret between the Gateway and access points and wireless clients. Please check whether
your service provider uses a default pre-shared key.
Pre-Authentication
Enables secure fast roaming, without noticeable signal latency. By default, this option is disabled.
W
WPPSS SSeettuupp
Using the WPS Setup menu, you can enable or disable WPS. WPS is a standard for easy
and secure wireless network set up and connections.
The advantages of WPS are:
!
WPS automatically configures the network name (SSID) and WPA security key for the
Gateway and for the access point and wireless devices that join the network.
!
You do not need to know the network name and security keys or passphrases to use
WPS to join a wireless network.
!
No one can guess your security keys or passphrase because they are generated
randomly.
!
WPS uses the Extensible Authentication Protocol (EAP), which is a strong authentication
protocol used in WPA2.
The disadvantages of WPS are:
!
Unless all the Wi-Fi devices on the network are WPS-compatible, you cannot take
advantage of the ease of securing the network.
!
Not all wireless equipment supports WPS.
