Authentication Type
: If your network uses LEAP to authenticate its users,
select
LEAP
from the drop down list.
LEAP
(Lightweight Extensible
Authentication Protocol) also known as Cisco-Wireless EAP provides
username/password-based authentication between a wireless client and a
RADIUS server. LEAP is one of several protocols used with the IEEE
802.1X standard for LAN port access control. LEAP also delivers a session
key to the authenticated station, so that future frames can be encrypted with
a key that is different than keys used by others sessions. Dynamic key
delivery eliminates one big vulnerability; static encryption keys that are
shared by all stations in the WLAN.

Enable WPA:
Place a check in this box if you would like to enable the WPA
function.
WPA
(Wi-Fi Protected Access) was 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.
h
Authentication Mode
: select an authentication mode from the drop-down
list. Options available are
Open
,
Shared
, or
AutoSwitch
. Select
AutoSwitch
if you would like the device to automatically switch between
Open and Shared authentication mode.
