to the settings without repeating the
configurations. For example, you
can set proles for work, home and
other situations. When you travel form home to work, choose the "ofce" prole
that contains all your settings for office use. When you travel back home,
choose the “home” prole.

Cong - Basic
This page enables you to change the
WLAN Card congurations.
Network Type
Infrastructure – Infrastructure means
to establish a connection with an access
point. Once connected, the access
point allows you to access wireless
LAN and wired LAN (Ethernet). The
Channel field turns to Auto if the
connection is based on Infrastructure.
Ad Hoc – Ad Hoc means to communicate directly with other wireless clients
without using an access point. An “Ad Hoc” network can be setup quickly
and easily without pre-planning, for example, sharing meeting notes between
attendants in a meeting room.
Network Name (SSID)
SSID stands for “Service Set Identifier”, which is a string used to identify a
wireless LAN. Use the SSID to connect with a known access point. You can
enter a new SSID or select one from the drop-down list box. If you get connected
by designating the SSID, you are only to connect the AP with the SSID you
assigned. If the AP is removed from the network, your WLAN Card does not
roam automatically to other APs. SSIDs must all be printable characters and
having a maximum of 32 case sensitive characters, such as “ Wireless”.
NOTE: Set the SSID to a null string, if you wish to allow your station to
connect to any access point it can nd. But you cannot use null string in
Ad Hoc mode.
Channel
The Channel eld is for setting radio channel. Your WLAN Card can automatically
select the correct channel to communicate with an wireless device, and the
parameter is xed to "Auto" in both Infrastructure and Ad Hoc mode.
The available radio channels depend on the regulations in your country. For
the United States (FCC) and Canada (IC), channel 1 to 11 are supported. For
Europe (ETSI), channel 1 to 13 are supported. For Japan (MKK), channel 1 to
14 are supported.

Cong - Advanced
Click Advanced link on Config-Basic
page to show this tab. This tab allows
you to set up additional parameters
for the wireless card. We recommend
using the default values for all items in
this window.
RTS Threshold (0-2347)
The RTS/CTS (Request to Send/Clear
to Send) function is used to minimize collisions among wireless stations.
When RTS/CTS is enabled, the router refrains from sending a data frame until
another RTS/CTS handshake is completed. Enable RTS/CTS by setting a
specic packet size threshold. The default value (2347) is recommended.
Fragmentation Threshold (256-2346)
Fragmentation is used to divide 802.11 frames into smaller pieces (fragments)
that are sent separately to the destination. Enable fragmentation by setting
a specic packet size threshold. If there is an excessive number of collisions
on the WLAN, experiment with different fragmentation values to increase the
reliability of frame transmissions. The default value (2000) is recommended for
normal use.

Network Authentication
Since there is no precise bound in
wireless LANs, the WLAN users need
to implement certain mechanism
to provide security solution. The
Authentication policies in this tab
provide protection of different levels
such as Open, WEP, WPA, and WPA2.
Open - Select this option to make the
network operate on Open System
mode, which use no authentication
algorithm. Open stations and APs can authenticate with each other without
checking any WEP Key, even if there is.
Shared - Select this option to make the network operate on Shared key mode.
In a Share Key Authentication system, four-step exchange of frames is required
to validate that the station is using the same WEP Key as the access point.
WPA-PSK/ WPA2-PSK - Select this option to enable WPA Pre-Shared Key
under Infrastructure mode. It enables communication between your client and
APs using WPA-PSK/WPA2-PSK encryption mode.
WPA/ WPA2 - The network is operating in IEEE 802.1x authentication mode.
This mode is for environments with RADIUS (Remote Access Dial-in User
Service). In a RADIUS environment, various Extensible Authentication Protocol
(EAP) are supported, including PEAP, TLS/Smart Card, TTLS, and LEAP.
Cong - Encryption
This page enables you to congure the Wireless LAN Card encryption settings.
For data confidentiality in a wireless environment, IEEE 802.11 specifies a
Wired Equivalent Privacy (WEP) algorithm to offer transmission privacy. The
WEP uses keys to encrypt and decrypt data packets. The encryption process
can scramble frame bits to avoid disclosure to others. The WPA/WPA2 is
improved security system for 802.11 which are developed to overcome the
weakness of the WEP protocol.

Data encryption
For Open and Shared authentication mode, the configuration options of
encryption type are Disabled and WEP. For WPA, WPA-PSK, WPA2 and
WPA2-PSK authentication mode, Temporal Key Integrity Protocol (TKIP)
encryption and Advanced Encryption Standard (AES) encryption are supported.
Disabled - Disable the encryption function.
WEP - WEP Key is used to encrypt your data before it is transmitted over air.
You can only connect and communicate with wireless devices that use the
same WEP keys.
TKIP - TKIP uses an encryption algorithm methods which is more stringent
than the WEP algorithm. It also uses existing WLAN calculation facilities to
perform encryption. TKIP veries the security conguration after the encryption
keys are determined.
AES: AES is a symmetric 128-bit block encryption technique which works
simultaneously on multiple network layers.
Wireless Network Key
This option is enabled only if you select WPA-PSK or WPA2-PSK authentication
mode. Select “TKIP” or “AES” in the encryption led as encryption mode to
begin the encryption proceed. Note: 8 to 64 characters are required in this eld.
Wireless Network Key (WEP)
This option is congurable only if you enable WEP in Network Authentication
eld. The WEP Key is a 64 bits (5 byte) or 128 bits (13 byte) Hexadecimal
digits which is used to encrypt and decrypt data packets.
Key Format
You can select to enter Hexadecimal digits (0~9, a~f, and A~F) or ASCII
characters to setup keys by dening the Key Format.
Key Length
For 64 bits encryption, each key contains 10 hex digits or 5 ASCII characters.
For 128 bits encryption, each key contains 26 hex digits or 13 ASCII characters.
Two ways to assign WEP keys
1. Manual Assignment - When you select this option, the cursor appears
in the eld for Key 1. For 64-bit encryption, you are required to enter four
WEP Keys. Each Key contains exactly 10 hex digits (0~9, a~f, and A~F).
For 128-bit encryption, you are required to enter four WEP Keys. Each Key
contains exactly 26 hex digits (0~9, a~f, and A~F).
