WIRELESS UTILITY SETTING
Windows® XP users may use the built-in wireless utility as default. The following
instructions are for Service Pack 2 users. If you are using Windows® 2000/98/ME,
you must use the Wireless Utility.
With the Wireless utility, users can configure all the functions provided by the
Wireless LAN Adapter Utility. Double-click the utility icon that appears in the
system tray.
The Wireless LAN Adapter Utility includes six tabs: Link Info, Configuration,
Advanced, Site Survey and About.
Link Info
The Link Info screen shows you the status of the Wireless Adapter, it shows that
where the device is connected to, the connect Status, the connecting Speed, the
network Type, the Encryption type, the SSID and the Signal Strength.
7

Configuration
This is the page where you can change the basic settings of the 802.11g Wireless
USB 2.0 Adapter with the minimum amount of effort to implement a secure
wireless network environment.
SSID: The SSID differentiates one Wireless LAN group name from another; so all
access points and all devices attempting to connect to a specific Wireless LAN
group name must use the same SSID. A device will not be permitted to join the
BSS unless it can provide the unique SSID.
Wireless Mode: If you want to connect with an Access Point/WLAN Router,
please set to “Infrastructure” mode. If you have more stations and just want to set
them as local network, please set the mode to “Ad-hoc” mode.
Channel: It shows auto that used for Infrastructure Wireless LAN network. The
channel number can be set only under the Ad-Hoc operation mode. In Ad-Hoc
mode stations, each station must have the same channel number and SSID.
In Infrastructure mode, the Wireless USB Adapter will automatically detect the
channel number of the Access Point.
Power Mode: There are 3 modes to choose:
Continuous Access Mode (default): The USB Dongle is constantly operating
with full power and it consumes the most power.
Maximum Power Save: The USB Dongle consumes the least power and only
operates when there is wireless network activity.
Power Save: The USB Dongle consumes the moderate level of power.

Preamble: Select Long or Short/Long (auto) Preamble type. Preamble is a
sequence of bits transmitted at 1Mbps that allows the PHY circuitry to reach
steady-state demodulation and synchronization of bit clock and frame start. Two
different preambles and headers are defined: the mandatory supported Long
Preamble and header, which interoperates with the 1 Mbit/s and 2 Mbit/s DSSS
specification (as described in IEEE Std. 802.11), and an optional Short Preamble
and header (as described in IEEE Std. 802.11b). At the receiver, the Preamble and
header are processed to aid in demodulation and delivery of the PSDU. The Short
Preamble and header may be used to minimize overhead and, thus, maximize the
network data throughput. However, the Short Preamble is supported only from the
IEEE 802.11b (High-Rate) standard and not from the original IEEE 802.11. That
means that stations using Short-Preamble cannot communicate with stations
implementing the original version of the protocol.
Support Band: There are two bands available for selection; 11B and 11G.
Advanced
The Advanced settings help you to control the Wireless Adapter to adjust with
wireless devices in certain environment.
Auth. Mode: Eight options are available: Disable, Auto, Open System, Shared Key,
WPA/WPA2, and WPA-PSK/WPA2-PSK. Select Auto, Disable for other
authentication feature. If one of the two options is selected, it is required to select
the Encryption mode from the next dropping list.

Shared Key/Open System
Network Key: Choose the encryption way, either in HEX or ASCII formats, and
enter the password in the blank space.
Key Length, Key Format and WEP Key: If you select 64bit in Hex format, you
must type 10 values in the following range (0~F, hexadecimal), or 64bit in ASCII
format, you must type 5 values in the following range (0~9, A~Z and a~z
Alphanumeric).
If you select 128bit in Hex format, you must type 26 values (0~F, hexadecimal), or
128bit in ASCII format, you must type 13 values in the following range (0~9, A~Z
and a~z Alphanumeric).
WPA-PSK / WPA2-PSK
Click the Configuration button than enter a Passphrase in the Define WPA PSK
dialog box. This Passphrase must be the same on each computer that is connected
to the wireless network.
10

WPA / WPA2
WPA2 (Wi-Fi Protected Access 2) is the second generation of WPA; providing
enterprise and consumer Wi-Fi user with a high level of assurance that only
authorized user can access their wireless networks. WPA2 is based on the final
IEEE802.11i amendment to the 802.11 standard and is eligible for FIPS 140-2
compliant. WPA2 is select, configuration is enabled. Please click the
“Certificate” button. The below window is pop up. Then, please select the
certificate that user wants to use and enter the server name and login name.
