card. This indicator helps to find the proper position of the
wireless device for quality network operation.
Signal Quality This bar indicates the quality of the link. The higher the
percentage, the better the quality.
9

Parameter Description
Network Name(SSID) The SSID (up to 32 printable ASCII characters) is the unique
name identified in a WLAN. The ID prevents the unintentional
merging of two co-located WLANs.
Only the wireless devices with the same SSID can interconnect.
Wireless Network Key(WEP) WEP is an authentication algorithm, which protects authorized
Wireless LAN users against eavesdropping. The security setting
must be the the same on the wireless stations within the network.
Data Encryption(WEP
Enabled) To enable the WEP function, select the check box.
Network Authenticaton
(Shared Mode) The wireless network supports two subtypes of network authentication services: Open System and Shared Key. Under
Open System authentication, any wireless stations can request
authentication. Under Shared Key authentication, only wirelss
stations using a shared key (WEP Key) are allowed to
authenticate mutually. This network authentication mode setting
has to be consistent with the wireless network which the card
intends to connect.
10

Parameter Description
Wireless Network Key(WEP)
Network Key If the network is required for Wired Equivalent Privacy (WEP) key,
type the key in the text box. The key should be 10 or 26
hexadecimal characters according to the WEP mode designated
by the network.
Note: The hexadecimal characters include the range of “A-F”, “a-
f” and “0-9”, for example: “0123456aef“ or
“01234567890123456789abcdef“.
Confirmed Network Key Enter the same network key again to cofirm the key.
Key Index(Advanced) Select one of the four keys to encrypt your data.
Enable IEEE 802.1x
authentication for this network IEEE 802.1x authentication provides enhanced security for wireless network. If the wireless network requries IEEE 802.1x
authentication for accessing to the network, please select the
check box.
The “EAP-MD5 Authentication“ screen (see the screen above) will
appear when you attempt to conenct the wireless network which
requires for IEEE 802.1x authentication. Please enter the user
name and password which your network administrator assigns to
you.
Note: This card only supports EAP-MD5 algorithm of the IEEE
802.1x authentication method when running in Windows
98SE/Me
/
2000/XP operating systems. Windows XP supports more
algorithm of IEEE 802.1x such as EAP-TLS, please uses the
Windows XP built-in Utility if you need to use the authentication
method other than EAP-MD5.
This is a comupter-to-
computer(ad hoc) network;
wireless access points are not
used
In Computer-to-Comupter mode (Ad Hoc), wireless stations
connect to each other directly, no Access Point is required. If the
wireless network you selected is in Ad Hoc mode, select this
check box.
3.3 Advanced Configuration
This screen allows you to do some advanced configuration including Power Save Mode,
Encryption Algorithm and some specific settings for the card.
11

Parameter Description
Ad Hoc Default Channel Select the number of the radio channel used for the Ad Hoc
networking. The channel of all the wireless stations in the Ad Hoc
network should be the same. The parameter is not active in the
infrastructure operation mode.
Note: The Infrastructure operation mode requires the presence of
an 802.11 Access Point. All communication is done via the
Access Point.
Encryption Algorithm The parameter is only active in the Ad Hoc operation mode. There
are three kinds of encrypion algorithm supported by the card
including WEP, TKIP and AES.
WEP is an authentication algorithm, which protects authorized
Wireless LAN users against eavesdropping. WEP has been found
that it has some security problems. TKIP is a temporary quick-fix
method defined in IEEE 802.11i standard to quickly overcome the
inherent weaknesses in WEP security. AES has been developed
to ensure the highest degree of security and authenticity for
digital information and it is the most advanced solution defined by
IEEE 802.11i for the security in the wireless network.
The security setting must be the the same on the wireless stations
within the network.
12

Parameter Description
Preamble Mode The preamble defines the length of the CRC block for
communication among the wireless stations. There are three
mode including Long, Short and Auto. High network traffic areas
should use the shorter preamble type. If “Auto“ mode is selected,
the card will auto switch the preamble mode depending on the
wireless stations which the card is connecting to.
Note that the parameter is only active in the Ad Hoc operation
mode.
Show Icon in System Tray Enable or disable the icon shown in the system tray.
Radio Off When the setting is checked, the wireless connection of the card
will be disabled.
Power Save •CAM(Continuous Access Mode) – This card will always set
in active mode.
•Max – Enable the card in the power saving mode when it is
idle.
•Fast – Enable the card in the power saving mode when it is
idle, but some compoents of the card is still alive. In this
mode, the power consumption is larger than “Max“ mode.
Rescan Button Click this button to scan the wireless network which the card is
connecting to.
