instructions below.

14
Profile Screen
System Config
Profile Name
Enter or select a suitable name for this profile. Each profile must
have a unique name.
SSID
If the desired wireless network is currently available, you can
select its SSID. Otherwise, type in the SSID of the desired wire-
less network.
Power Save Mode
Select either CAM (Constantly Awake Mode) or PSM (Power
Saving Mode).
RTS Threshold
Select a value within the range of 0 to 2347 bytes
Fragment Threshold
Select the value from 256 to 2346 bytes. The default value is
2346.
Network Type
Select the desired option:
Infrastructure - Select this to connect to an Access point.
Ad-Hoc - Select this if you are connecting directly to another
computer.
Tx Power
Select the Tx (transmission) power according to the real environ-
ment.
Preamble

check). Select either Auto or Long Preamble.
OK button
Click this button to save the settings and close the page.
Cancel button
The "Cancel" button will discard any data you have entered and
exit the page.

15
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 me-
thod can only be used with WEP.
LEAP - Light Extensible Authentication Protocol is a pre-EAP,
Cisco-proprietary protocol. If selected, you have to enter the iden-
tity, 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 stan-
dard.
WPA-PSK - PSK means "Pre-shared Key". You must enter this
Passphrase value; it is used for both authentication and encryp-
tion.
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 Passphrase
value; it is used for both authentication and encryption.
WPA None - If selected, you can only set encryption and WPA-
Preshared Key settings.

16
Encryption
The available options depend on the Authentication method se-
lected 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 allowed to
be entered.

17
802.1x
EAP Method
There are 5 methods in the drop-down list.
PEAP - Protect Extensible Authentication Protocol. PEAP trans-
port securely authentication data by using tunneling between
PEAP clients and an authentication server. PEAP can authenti-
cate wireless LAN clients using only server-side certificates, thus
simplifying the implementation and administration of a secure
wireless LAN.
TLS-Smart Card - Transport Layer Security. Provides for certifi-
cate-based and mutual authentication of the client and the
network. It relies on client-side and server-side certificates 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. Unlike 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, mutual authen-
tication is achieved by means of a PAC (Protected Access
Credential) which can be managed dynamically by the authentica-
tion server. The PAC can be provisioned (distributed 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, distri-
bution.
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.

18
Tunnel Authentica-
tion
Select the desired option from the drop-down list.
Session Resump-
tion
After reconnecting the signal which broke up, you can enable the
session resumption to reduce the transferring packet to accele-
rate the speed.
Authentication ID /
Password
Enter the required data into the fields.
Tunnel ID / Pass-
word
Enter the ID and Password for the tunnel.
Use Client certifi-
cate
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.

5.2. Network
The network setting page allows you to set and save different wireless settings. You can activate
the suitable profile according to the environment where the wireless connection is used.
This screen is displayed when you double-click the system tray icon. You can also click the Net-
work tab in the screen.
When you open the utility program, it will scan all the channels to find all the access
points/stations within the accessible range and automatically connect to one of the wireless devic-
es which have the highest signal strength.
