Authentication You MUST select the option to match the Wireless LAN you
wish to join. The available options are:
• Open System - Broadcast signals are not encrypted. This
method can be used only with no encryption or with WEP.
• Shared Key - Broadcast signals are encrypted using WEP.
This method can only be used with WEP.
• WPA-PSK - PSK means "Pre-shared Key". You must enter
this Passphrase value; it is used for both authentication and
encryption.
• WPA2-PSK - This is a further development of WPA-PSK,
and offers even greater security. You must enter this
Passphrase value; it is used for both authentication and en-
cryption.
• WPA 802.1x - This version of WPA requires a Radius
Server on your LAN to provide the client authentication ac-
cording to the 802.1x standard. Data transmissions are
encrypted using the WPA standard.
• WPA2 802.1x - This version of WPA2 requires a Radius
Server on your LAN to provide the client authentication ac-
cording to the 802.1x standard. Data transmissions are
encrypted using the WPA2 standard.
• WEP 802.1x - This version of WEP requires a Radius Server
on your LAN to provide the client authentication according
to the 802.1x standard. Data transmissions are encrypted us-
ing the WEP standard.
Data Encryption The available options depend on the Authentication method
selected above. The possible options are:
• Disabled - 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 802.1x and WPA2 802.1x. Select the cor-
rect option.
Passphrase For WEP 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.
Select the desired option, and ensure the Wireless Stations use the
same setting.
• 64 Bit - data is encrypted, using the default key, before being
transmitted. You must enter at least the default key. For 64
Bit Encryption, the key size is 10 chars in HEX (0~9 and
A~F).
• 128 Bit - data is encrypted, using the default key, before
being transmitted. You must enter at least the default key.
For 128 Bit Encryption, the key size is 26 chars in HEX (0~9
and A~F).

ASCII Numerical values, characters or signs are all allowed to be
entered.
Key Index (1~4) This setting is only available for Open System or Shared Key
mode.
Network 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.
Confirm network key Re-enter the value in this field.
802.1x
EAP Method There are 5 methods in the drop-down list.
• GTC - Generic Token Card. It was created by Cisco. It
carries a text challenge from the authentication server, and a
reply which is assumed to be generated by a security token.
GTC does not protect the authentication data in any way.
• TLS - Transport Layer Security. Provides for certificate-
based and mutual authentication of the client and the net-
work. It relies on client-side and server-side certificates to
perform authentication and can be used to dynamically gen-
erate user-based and session-based WEP keys to secure
subsequent communications between the WLAN client and
the access point.
• LEAP - Lightweight Extensible Authentication Protocol. It
is a proprietary protocol from Cisco Systems developed to
address the security weaknesses common in WEP.
• TTLS - Tunneled Transport Layer Security. This security
method provides for certificate-based, mutual authentication
of the client and network through an encrypted channel.
Unlike EAP-TLS, EAP-TTLS requires only server-side cer-
tificates.
• 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.
Tunnel Select the desired option from the drop-down list.
Provision Mode Select the desired mode from the drop-down list.
Username Enter the user name into the field.
Identity Enter the data in the field.
Domain Type the domain name you want into the field provided.
Password Enter the password for the tunnel.
Certificate Click the checkbox to enable certificate authority server function.
Select the desired option from the list.
PAC Select the desired option from the list.
