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).
