A group of wireless users and an Access Point compose a Basic Service Set (BSS).
Wireless clients can talk to any computer in both wired and wireless LAN network via
the Access Point.
2-2 Roaming
Infrastructure mode also supports roaming capabilities for mobile users. More
than one BSS can be configured as an Extended Service Set (ESS). The continuous
network allows users to roam freely within an ESS. All wireless USB Adapter and
Access Point within one ESS must be configured with the same ESSID in order to
utilize the roaming function. Proper Access Point positioning with a clear radio signal
can greatly enhance wireless performance.

Chapter 4 Wireless Utility and Configuration
The following sections describe the Wireless Network Configuration Utility.
This utility provides quick access and a friendly user-interface to configure the card
setup.
4-1 Windows 98/2000 Wireless Utility
After installation is completed, a Wireless LAN Utility icon will appear in
Desktop screen. Click it, then you will see the screen below. If you cannot find the
icon, you can select “Start” ->”Programs”->”Wireless LAN Configuration Utility”
Icon.
Card Status: You can see the AP information that your card connected. In this page
you also can find Firmware Version and manufacturer information.
ESSID: An acronym for Extended Service Set Identifier, ESSID is the unique name
shared among all clients and Access Points in a wireless network. The ESSID must be
identical for all clients or Access Points participating in the same network. The ESSID
is case sensitive and must not exceed 30 characters. Pressing ‘Rescan,’ will scan all
the APs in the nearby area and choose the strongest one. Using “Link Quality” and
“Signal Strength”, you can determine the wireless transmission quality.
Press ‘Config Adapter’ tab, then you will see the screen below.
There are two network types:
Ad-Hoc: This mode is used for a simple peer-to-peer network. It offers file sharing
between wireless clients without a wireless Access Point (AP).
Infrastructure (Default): This mode allows a wireless LAN to be integrated into an
existing wired network through an AP. Infrastructure type networks also permit
roaming between Access Points while maintaining connection to all network
resources. Infrastructure mode provides additional features, such as WEP security,
power saving and extended range.
ESSID: You can either choose specific AP or connect to any AP in the nearby area.
Power Save: enable it, so it will be triggered when your computer system is inactive.
After computer system active again, wireless connection will rebuild.
Auto Renew IP: Select this item, so the wireless network card can automatically gain
an IP when you move to another network subnet. For example, if you are in
192.168.1.X subnet and move to 192.178.5.X subnet, your computer will renew an IP
address from 192.178.5.X subnet.
Press ‘Card Encryption’ tab, then you will see the screen below.
Wired Equivalent Privacy, WEP is an encryption scheme used to protect your
wireless data communications. WEP uses a combination of 64-bit keys,128-bit keys
to provide data encryption for your wireless network. AP and wireless card should use
the same WEP key in order to communicate
Use the Site Survey Tool. You can identify each channel transmission quality.
4-2 Windows XP Wireless Utility
NOTE: You do not need to install the utility from the CD if you are using Windows
XP. Windows XP provides wireless Utility as below.
1. To configure the wireless card setting, you can select Start\Settings\Network
Connection in the Windows XP. Choose the wireless network connection, then
you will see below screen. From this screen, you can see wireless connection
status and wireless signal level.
2. Select ‘Properties’ in the above screen. The following windows will show up.
In ‘General’ page, wireless card information and networking protocol have been
displayed. Extra networking protocol can be installed in this page.
3. Select Wireless Networks page, you can see available wireless networks in your
nearby area. You can add your preferred wireless Access Point to your list, so your
wireless card will search for specific wireless networks.
3. Click ‘Configure’ above to setup wireless security and data encryption.
Define your network name (SSID) in the following windows, so your can join a
specific wireless network. Check AP has WEP on or not. You wireless network will
need to have same WEP setting with AP in order to communicate. If your wireless
network don’t have any AP, mark the ‘This is computer-to computer (ad-hoc) network;
wireless access points are not used’
This window provides authentication via 802.1X. 802.1X, an IEEE standard that
provides an authentication framework for 802-based LANs. 802.1X takes advantage
of an existing authentication protocol known as the Extensible Authentication
Protocol. 802.1x, giving someone secure, encrypted, wireless access on a Microsoft
network will be as easy as setting a flag on the users domain account.
What does this mean for the Home Network user?
802.1x will ensure that if and when you make the change over to Wireless Ethernet,
your neighbor will not be able to access your wireless LAN!
The ‘Advanced’ window offers Firewall and Internet Connection Sharing functions.
Depending on your networking environment, you can select the functions below.
Appendix A Troubleshooting
Problem Solving
1. My computer does not recognize the wireless network card.
Solution:
??The wireless network card is not properly inserted into the USB Adapter slot.
??Ensure that the wireless network card has been inserted into an available USB
Adapter .
2. The wireless network card does not work properly.
Solution:
??Insert the USB Adapter into Notebook’s slot again. A beep should be heard if the
card properly inserted.
??The Activity LED indicator is active if the card is properly connected.
??Right click on “My Computer” and the select Properties. Select the device
Manager and click on the Network Adapter. You will find “LAN-Express IEEE
802.11 USB Adapter” if it is installed successfully. If you see the Yellow
Question Mark besides the wireless network card, then the wireless card is not
properly installed. Please check below:
?? Check if your Notebook has a free IRQ
?? Check that you have inserted the right card and have installed the proper
driver.
?? Try to remove driver, install again, and then reboot your computer.
??Confirm the station is configured the same ESSID as the same wireless network.
??Check your channel is the same as AP setting. Try to use ‘Rescan’ function in
the card status page after launch Wireless Utility.
Appendix B Glossary
Access Point - An internetworking device that seamlessly connects wired and
wireless networks together.
Ad-Hoc - Ad-Hoc is a peer- to-peer wireless network without Access Point. A group
of wireless clients consistent an independent wireless LAN.
Backbone - The core infrastructure of a network, the portion of the network that
transports information from one central location to another central location. The
information is then off-loaded onto a local system.
BSS - Stands for “Basic Service Set.” An Access Point associated with several
wireless stations.
ESS - Stands for “Extended Service Set.” More than one BSS can be configured as an
Extended Service Set. An ESS is basically a roaming domain.
Ethernet - A popular local area data communications network, originally developed
by Xerox Corp., which accepts transmission from computers and terminals. Ethernet
operates on 10/100 Mbps transmission rate over shielded coaxial cable or over
shielded twisted pair telephone wire.
Infrastructure - An integrated wireless and wired LAN is called an Infrastructure
configuration.
USB ADAPTER - Personal Computer Memory Card International Association,
which develops standards for PC cards, formerly known as USB Adapter, are
available in three “types” which are about the same length and width as credit cards,
but range in thickness from 3.3 mm (Type I) to 5.0 mm (Type II) to 10.5 mm (Type
III). These cards can be used for many functions, including memory storage, as
landline modems and as wireless LAN.
Roaming - A function that allows one to travel with a mobile end system (wireless
LAN mobile station, for example) through the territory of a domain (an ESS, for
example) while continuously connecting to the infrastructure.
