Unless one of these encryption modes is selected, wireless
transmissions to and from your wireless network can be easily
intercepted and interpreted by unauthorized users.
The security modes are described below:
Open: You can authenticate successfully with a SSID, whether it is
valid or empty.
Shared: The WLAN clients who have the same WEP key with
wireless gateway can pass the authentication and access the
wireless network.
WEPAUTO: Select WEP security automatically.
WPA-PSK: WPA Pre-Shared Key, Enter the Pre-Shared key as a
plain text (ASCII) pass-phrase of at least 8 characters.
WPA2-PSK:It is the securer version of WPA with implementation
of the 802.11i standard.
WPA-PSK/WPA2-PSK:Apply both the WPA-PSK and WPA2-PSK
scheme.
If the Authentication type is Open, Shared, WEPAUTO, the bottom
part of the configuration page displays parameters as shown.

must also enter the same keys for the client adapter in the same
order. In other words, WEP key 1 on the AP must match WEP
key 1 on the client adapter, WEP key 2 on the AP must match
