long as it conforms to any MAC address filter policies that may have been set. All
authentication packets are transmitted without encryption. Shared Key sends an
unencrypted challenge text string to any device attempting to communicate with the
AP. The device requesting authentication encrypts the challenge text and sends it
back to the access point. If the challenge text is encrypted correctly, the access point
allows the requesting device to authenticate. It is recommended to select Auto if you
are not sure which authentication type is used.
Key Length : Select a 64-bit or 128-bit WEP key length from the drop-down list.
Key Type : Select a key type from the drop-down list. 128-bit encryption requires a
longer key than 64-bit encryption. Keys are defined by entering in a string in HEX
(hexadecimal - using characters 0-9, A-F) or ASCII (American Standard Code for
Information Interchange - alphanumeric characters) format. ASCII format is provided
so you can enter a string that is easier to remember.
Default Key : You may choose one of your 4 different WEP keys from below.
Encryption Key 1-4: You may enter four different WEP keys.
Enable 802.1x Authentication : Place a check in this box if you would like to use
RADIUS authentication. This option works with a RADIUS Server to authenticate
wireless clients. Wireless clients should have established the necessary credentials
before attempting to authenticate to the Server through this Gateway. Furthermore, it
may be necessary to configure the RADIUS Server to allow this Gateway to
authenticate users. You will then be required to specify the RADIUS Server’s IP
address, port, and password.

3.2.4.5.4.3 WPA (Wi-Fi Protected Access) / Pre-shared
Key
Click on the Security link under the Wireless drop-down menu.
WPA (Wi-Fi Protected Access) is designed to improve upon the security features of
WEP (Wired Equivalent Privacy). The technology is designed to work with existing
Wi-Fi products that have been enabled with WEP. WPA provides improved data
encryption through the Temporal Integrity Protocol (TKIP), which scrambles the keys
using a hashing algorithm and by adding an integrity checking feature which makes
sure that keys haven’t been tampered with.
