Auth./Encyp.
Authentication You MUST select the option to match the Wireless LAN you
wish to join. The available options are:
•Open - Broadcast signals are not encrypted. This method can
be used only with no encryption or with WEP.
•Shared - Broadcast signals are encrypted using WEP. This
method can only be used with WEP.
•LEAP - Light Extensible Authentication Protocol is a pre-
EAP, Cisco-proprietary protocol. If selected, you have to en-
ter the identity, password and domain name of your
computer.
•WPA - This version of WPA requires a Radius Server on
your LAN to provide the client authentication according to
the 802.1x standard. Data transmissions are encrypted using
the WPA standard.
•WPA-PSK - PSK means "Pre-shared Key". You must enter
this Passphrase value; it is used for both authentication and
encryption.
•WPA2 - This version of WPA2 requires a Radius Server on
your LAN to provide the client authentication according to
the 802.1x standard. Data transmissions are encrypted using
the WPA2 standard.
•WPA2-PSK - This is a further development of WPA-PSK,
and offers even greater security. You must enter this Pass-
phrase value; it is used for both authentication and
encryption.
•WPA None - If selected, you can only set encryption and
WPA-Preshared Key settings.

Encryption The available options depend on the Authentication method
selected above. The possible options are:
•None - No data encryption is used.
•WEP - If selected, you must enter the WEP data shown
below. This WEP data must match the Access Point or other
Wireless stations.
•AES, TKIP - These options are available with WPA-PSK,
WPA2-PSK, WPA and WPA2. Select the correct option.
Use 802.1x This setting only takes effect when using Open, Shared, WPA or
WPA2 mode. If enabled, click the 802.1x tab to configure the
related settings.
WPA Preshared Key For WPA-PSK and WPA2-PSK modes, you need to enter the
desired value (8~63 characters). Data is encrypted using a 256Bit
key derived from this key. Other Wireless Stations must use the
same key.
WEP Key (1~4) This setting is only available for Open or Shared mode.
There are 2 modes:
•Hex - Only "A~F", "a~f", and "0~9" are allowed to be
entered.
•ASCII - Numerical values, characters or signs are all al-
lowed to be entered.

Using the Windows Utility

802.1x
EAP Method There are 5 methods in the drop-down list.
•PEAP - Protect Extensible Authentication Protocol. PEAP
transport securely authentication data by using tunneling be-
tween PEAP clients and an authentication server. PEAP can
authenticate wireless LAN clients using only server-side cer-
tificates, thus simplifying the implementation and
administration of a secure wireless LAN.
•TLS-Smart Card - Transport Layer Security. Provides for
certificate-based and mutual authentication of the client and
the network. It relies on client-side and server-side certifi-
cates to perform authentication and can be used to
dynamically generate user-based and session-based WEP
keys to secure subsequent communications between the
WLAN client and the access point.
•TTLS - Tunneled Transport Layer Security. This security
method provides for certificate-based, mutual authentication
of the client and network through an encrypted channel. Un-
like EAP-TLS, EAP-TTLS requires only server-side
certificates.
•EAP-FAST - Flexible Authentication via Secure Tunneling.
It was developed by Cisco. Instead of using a certificate, mu-
tual authentication is achieved by means of a PAC (Protected
Access Credential) which can be managed dynamically by
the authentication server. The PAC can be provisioned (dis-
tributed one time) to the client either manually or
automatically. Manual provisioning is delivery to the client
via disk or a secured network distribution method. Automatic
provisioning is an in-band, over the air, distribution.
•MD5-Challenge - Message Digest Challenge. Challenge is
an EAP authentication type that provides base-level EAP
support. It provides for only one-way authentication - there is
no mutual authentication of wireless client and the network.
Tunnel Authentica-
tion Select the desired option from the drop-down list.
Session Resumption After reconnecting the signal which broke up, you can enable the
session resumption to reduce the transferring packet to accelerate
the speed.
Authentication ID /
Password Enter the required data into the fields.
Tunnel ID / Password Enter the ID and Password for the tunnel.
Use Client certificate Click the checkbox to enable certificate authority server function.
Use certificate chain When the EAP authentication type such as TLS, TTLS or PEAP
is selected and required a certification to tell the client what
server credentials to accept from the authentication server in
order to verify the server, you have to enable this function and
enter the required data in the related fields.
