1. Network Implementation Using The product
There are two possible types of wireless network configurations using the product:
(1) Infrastructure (wireless network using an Access Point)
Using the Client/Server or Master/Slave concept, an Access Point is used to link a wired
network with wireless clients. Not only can the wireless clients access the wired network
but they can also access each other via the Access Point. Multiple Access Points can
be used in the same infrastructure network in order to extend the wireless network
range or share the workload of handling more wireless clients.
(2) Ad-Hoc (wireless network not using an Access Point)
Since there is no Access Point to act as a link to a wired network, wireless network
nodes can only access each other but cannot access a wired network or the Internet.
2. Before Installation
Package Contents
Unpack and confirm that the following contents (in addition to this User Manual) are
included:
Wireless A/G Portable USB Adapter (1 ea.)
Installation CD (1 ea.)
Quick Installation Guide (1 ea.)
To Prepare Before Installation
Ask your system administrator for the following information, which you may need to input
during installation:

7
- Your SSID (group name of the wireless network)
- If you are using a fixed IP address: IP address, gateway address, and subnet mask
info.
To use the Wireless A/G Portable USB Adapter, the device must be equipped with an
internal or external USB slot.
You should have the latest drivers and utility software for the product (please visit our
website for the latest drivers and utility software).

3. Installing the Wireless A/G Portable USB Adapter
The following explanation is based on installation of the Wireless A/G Portable USB Adapter
into a PC running the Windows XP operation system. Installation in PCs running Windows
98SE, Me, 2000 or XP may be slightly different than shown here.
3.1. Connect the Wireless A/G Portable USB Adapter into the PC's USB slot. The PC will
automatically detect the Wireless A/G Portable USB Adapter and display the [Found New
Hardware Wizard] window.
3.2. Click on [Cancel] and exit the [Found New Hardware Wizard] window.
3.3. Insert the Installation CD into the PC's CD-ROM drive and run Windows Explorer to locate
the file named "Setup.exe" (if CD-ROM drive is D, then the file is under the directory
D:\Client). Once found, double-click on "Setup.exe" and the following screen will appear.

9
3.4. Click on [Next] and the utility program will be automatically installed as shown in the
following screen.
3.5. The following screen will appear when installation is completed. Click on [Finish] to
successfully exit the installation process.

4. The Client Utility Program
The following are explanations on how to configure and use the Client Utility program.
How to Use the Utility Program
After completing the above installation and configuration procedures, a new icon as shown
below will automatically appear in the lower right tray bar.
Double-clicking on the icon will display the following [Client Utility] window.
Each of the pages (Network, Profile, Search, Option, Version) presented in the Client Utility
is explained in the following sections.

11
[Network]
This page shows how the network is presently configured: network mode, information on
the connected AP, TCP/IP, etc. This information cannot be modified in the Network screen.
The “Current Status” window shows the signal quality, signal strength, channel, etc.
between the client and AP. It is always in view regardless of which page (Network, Profile,
Search, Option, Version) is selected within the Client Utility.

12
[Profile]
This page is used to manage connection with Access Points. You can create different
configuration profiles for connections with different APs and SSIDs.
The advantage of saving different profiles is the easiness of quickly changing connections
without having to configure the PC with every single variable each time a connection
change is made. Also, when configuring TCP/IP via the Client Utility you do not need to
reboot the PC as when TCP/IP configuration is done via Windows' Control Panel.
Explanation of each button in this page is shown below.
Add
Clicking on this button enables you to create a new profile. The following steps show
how this can be done.
1) Click on [Add] and the following screen will appear. Select the configuration method,
[Express Setup] or [Advanced Setup], and follow the on-screen instructions. The
following steps are for the [Express Setup]. If you decide to select [Advanced Setup],
please refer to section Property shown on pages 21 ~ 23

13
2) Select [Express Setup] and click on [Next]. The following screen will appear.
Type in the new profile name for the new wireless connection.
3) Click on [Next] and the following screen will appear.

14
Select a “Network Mode” (Infrastructure or Ad-Hoc) and “SSID”. You do not need to
change the default settings of "Power Save Mode" and "Roaming Optimization"
unless there is a special need to do so. Refer below for further explanation of each
mode.
Reference
Network Mode
Infrastructure:You will need an 802.11a/g Access Point to use the device in Infrastructure
mode. Because all communication will be done via the Access Point, the Access Point’s
SSID must be used.
Ad-Hoc: In Ad-Hoc mode communication is made peer-to-peer between the client PCs and
without the use of an Access Point. All PCs communicating in an Ad-Hoc should use the
same SSID (whatever your choice is).
SSID: The SSID is a group name used by users of a common wireless network. Only those
devices using the same SSID are able to access each other. Also, you must use the same
SSID as the Access Point you want to connect with.

15
If you do not know the SSID of the devices you want to connect with or want to
know the SSIDs of any wireless LAN devices operating in the vicinity, click on
[Browse] and the following [Site Survey] screen will appear. Click on [Refresh] to
update the list of available SSIDs in the vicinity.
[Refresh] will scan the vicinity of a certain amount of time and display the scan
results.
The site survey list will present you with information containing each device's SSID,
signal strength, signal channel, BSSID (MAC address), data rate, and WEP status
(on or off).
Click on a SSID in the site survey list and click on [Add to profile]. You will then be
taken back to the previous [Profile wizard] screen and the selected SSID will be
automatically inserted into the SSID input line (in this example: office1) as shown
below.

16
4. Click on [Next] and the following screen will appear.
Click on [Apply this profile now] to immediately make this profile effective as the
current profile and connect to the selected SSID. If you choose to only save the
new profile without making it the current profile, do not select this option.
5. Click on [Save] and you will be taken back to the [Profile] page and the new profile
automatically added to the “Profile List”.

17
Remove
To remove a profile from the “Profile List” select it and then click on [Remove].
Apply
If you want to change the current profile with another profile from the “Profile List”,
select the desired profile and click on [Apply]. The new profile will immediately
become the current profile and you will be connected with its SSID.

18
Property
Selecting a profile from the “Profile List” and clicking on [Property] will allow you to
check and/or modify the properties of the selected profile. Clicking on [Property] will
take you to the following screen. Each page in [Property] is explained below.
General: In this page, you can verify the profile name of the current profile.
Wireless Network: In this page, you can configure parameters such as Network
Mode, SSID, and others.

19
WEP (Wired Equivalent Privacy): In this page, you can modify features of the WEP
encryption system such as WEP Key, 64 or 128-bit encryption, etc.
When using WEP encryption (available in 64 or 128-bit), only those APs and PCs
using the same WEP Key are allowed to communicate with each other.
There are three ways of generating a WEP Key:

20
- Make key using PassPhrase: a WEP Key is automatically generated as you
type in any PassPhrase of your choice.
-Manual Input (ASCII): You generate your own WEP Key using ASCII characters
(5 characters for 64-bit and 13 characters for 128-bit).
- Manual Input (Hexadecimal): You generate your own WEP Key using
hexadecimal characters (10 characters for 64-bit and 26 characters for 128-bit).
Advanced: In this page, advanced hardware properties can be modified. Unless you
are an advanced user and have deep knowledge about each property in this page,
it is recommended that you leave them at the default settings.
