6.5.4 Wireless Security: WPA(2)

WPA (Wi-Fi Protected Access) is a subset of the IEEE 802.11i standard. WPA2 (IEEE
802.11i) is a wireless security standard that defines stronger encryption, authentication and
key management than WPA. Key differences between WPA(2) and WEP are user
authentication and improved data encryption.

DESCRIPTION
If you want to manually set the WEP keys, enter the WEP key in the field provided.
Select a WEP key to use for data encryption.
The WEP keys are used to encrypt data. Both the device and the wireless stations
must use the same WEP key for data transmission.
If you chose 64 bit WEP, then enter any 5 ASCII characters or 10 hexadecimal
characters ("0-9", "A-F").
If you chose 128 bit WEP, then enter 13 ASCII characters or 26 hexadecimal
characters ("0-9", "A-F").
If you chose 152 bit WEP, then enter 16 ASCII characters or 32 hexadecimal
characters ("0-9", "A-F").
Enter the IP address of the external authentication server in dotted decimal
notation.
Enter the port number of the external authentication server. The default port
number is 1812.
You need not change this value unless your network administrator instructs you to
do so with additional information.
Enter a password (up to 63 printable characters) as the key to be shared between
the external authentication server and the device.
The key must be the same on the external authentication server and your device.
The key is not sent over the network.
Specify how often wireless stations have to resend user names and passwords in
order to stay connected. Enter a time interval between 100 and 3600 seconds.
If wireless station authentication is done using a RADIUS server, the
reauthentication timer on the RADIUS server has priority.
This is how often the AP sends a new group key out to all clients. The re-keying
process is the WPA equivalent of automatically changing the WEP key for an AP
and all stations in a WLAN on a periodic basis.
Specify an interval either in seconds or thousands of packets that the device
sends.
Click Apply to save your changes back to the device.
