Encryption
Encryption – Wired Equivalent Privacy (WEP) is implemented in the adapter to prevent
unauthorized access. For more secure data transmissions, set encryption to “128-bit” or
“64-bit”. The 128-bit setting gives a higher level of security. The setting must be the
same
for all clients in your wireless network. (Default: Disabled.)
The WEP (Wired Equivalent Privacy) implemented in Wireless PC Card is based on the
RC4 encryption algorithm. The security keys are four 10 digit keys for the 64-bit WEP
setting and one 26-digit key for the 128-bit WEP setting. WEP security protects your
wireless LAN against eavesdropping and unauthorized access by hackers or intruders.
Create with Passphrase – Security keys for WEP encryption are generated from your
Passphrase string, so you must use the same passphrase on all the other stations in your
network.
Utility Configuration
13
Manual Entry – “Manual Entry” allows you to manually enter key elements (two
hexadecimal digits in each block, 0~9 & A~F, e.g., D7 0A 9C 7F E5.)
Default Key ID – Choose the Key ID that has the encryption string you prefer. If you are
using a key generated from the passphrase, you must use the same passphrase and key
on each station.
To use the WEP function, take the following steps:
1. Select “128-bit” or “64-bit” in the “Encryption” field.
2. Choose “Create with Passphrase,” type a string in the Passphrase field, and click
“Generate.”
3. Select the key, and click “Apply.”
Note: A passphrase string can consist of up to 32 alphanumeric characters.
Or
1. Check “Manual Entry” and enter hexadecimal numbers into one of the key fields. The

Network Configuration and Planning
18
Network Configuration and Planning
The Wireless Solution supports a stand-alone wireless network configuration, as well as
an integrated configuration with 10/100 Mbps Ethernet LANs.
The Wireless PC Card can be configured as:
•Ad hoc - for small groups that only communicate with each other
•Infrastructure - for wireless LANs
Network Topologies
Ad Hoc Wireless LAN
An ad hoc wireless LAN consists of a group
of computers, each equipped with one
wireless adapter, connected via radio signals
as an independent wireless LAN. Computers
in a specific ad hoc wireless LAN must
therefore be configured to the same radio
channel. An ad hoc wireless LAN can be
used in a SOHO or temporary environment.
Infrastructure Wireless LAN
The access point can also provide wireless
workstations with access to a wired LAN. An integrated wired and wireless LAN is called
an infrastructure configuration. A Basic Service Set (BSS) consists of a group of wireless
PC users, and an access point that is directly connected to the wired LAN. Each wireless
PC in this BSS can talk to any computer in its wireless group via a radio link, or access
other computers or network resources in the wired LAN infrastructure via the access
point.
The infrastructure configuration not only extends the accessibility of wireless PCs to the
wired LAN, but also extends the effective wireless transmission range for wireless PCs by
passing their signal through one or more access points.

Network Configuration and Planning
19
A wireless infrastructure can be used for access to a central database, or for connection
between mobile workers, as shown in the following figure.
Setting the Communication Domain
Stationary Wireless PCs
The Basic Service Set (BSS) is the communication domain for each access point. For
wireless PCs that do not need to support roaming, set the domain identifier (SSID) for the
wireless card to the SSID of the access point you want to connect to. Check with your
administrator for the SSID of the access point you should connect to.
Roaming Wireless PCs
A wireless infrastructure can also support roaming for mobile workers. More than one
access point can be configured to create an Extended Service Set (ESS). By placing the
access points so that a continuous coverage area is created, wireless users within this
ESS can roam freely. All wireless adapters and access points within a specific ESS must
be configured with the same SS ID and to the same radio channel.

Troubleshooting
Check the following troubleshooting items before contacting your dealer’s Technical
Support.
Adapter Installation Problems
If your computer cannot find the Wireless PC Card or the network driver does not install
correctly, check the following:
•Make sure the adapter is securely seated in the PCMCIA slot. When you insert the
wireless adapter into the notebook’s slot, a beep should be heard if the adapter is
properly inserted. Check for any hardware problems, such as physical damage to the
card’s connector.
•Try the card in another PCMCIA slot. If this also fails, test your computer with another
Wireless PC Card that is known to operate correctly.
•When operating under Windows NT, make sure a PCMCIA card and socket services
driver is installed in your computer. Also check for resource conflicts using the Windows
NT Diagnostics utility.
•Make sure your computer is using the latest BIOS.
•If there are other network adapters in the computer, they may be causing conflicts.
Remove all other adapters from the computer and test the wireless adapter separately.
•If it still does not work, take out the wireless adapter. Delete CW10.sys from
c:\windows\system. Then go to “Control Panel” and delete the adapter from your
network configuration menu. Restart your PC and reinstall the card.
Network Connection Problems
If the Link LED on the PC Card does not light, or if you cannot access any network
resources from the computer, check the following:
•Make sure the correct software driver is installed for your operating system. If
necessary, try reinstalling the driver.
•Make sure the computer and other network devices are receiving power.
•The access point you want to attach to may be defective. Try using another access
point.
•If you cannot access a Windows or NetWare service on the network, check that you
have enabled and configured the service correctly. If you cannot connect to a particular
server, be sure that you have access rights and a valid ID and password.
•If you cannot access the Internet, be sure you have configured your system for TCP/IP.
Troubleshooting
22
If your wireless station cannot communicate with a computer in the Ethernet LAN when
configured for Infrastructure mode, check the following:
•Make sure the access point that the station is associated with is powered on.
•If you still can’t connect, change the access point and all the stations within the BSS to
another radio channel.
•For a station with roaming disabled, make sure the SSID is the same as that used by
the access point, or the same as that used by the access points in the extended service
set (ESS.)

CSMA/CA – Carrier Sense Multiple Access with Collision Avoidance.
ESS – ESS (ESS-ID, SSID) stands for “Extended Service Set.” More than one BSS is
configured to become an Extended Service Set. LAN mobile users can roam between
different BSSs in an ESS (ESS-ID, SSID).
Ethernet – A popular local area data communications network, which accepts
transmission from computers and terminals. Ethernet operates on a 10 Mbps baseband
transmission rate, using shielded coaxial cable or shielded twisted-pair telephone cable.
Fragmentation Threshold – In the 802.11 Standard, the MAC Layer may fragment and
reassemble directed MSDUs or MMPDUs. The fragmentation and defragmentation
mechanisms allow for fragment re-transmission.
Infrastructure – An integrated wireless and wired LAN is called an Infrastructure
network.
Preamble Type – Some Access Points and Client card drivers have a radio setting for
“Short” RF Preamble. If all the Clients and Access points in your wireless network have
this feature, then enabling it can boost your throughput. However, if a radio does not
support this feature, then it will not be able to communicate with any other radios that
have this set to “Short.”
Roaming – A wireless LAN mobile user moves around an ESS and maintains a
continuous connection to the Infrastructure network.
RTS Threshold – Transmitters contending for the medium may not be aware of each
other. The RTS/CTS mechanism can solve this “Hidden Node Problem.” If the packet size
is smaller than the preset RTS Threshold size, the RTS/CTS mechanism will NOT be
enabled.

WEP – “Wired Equivalent Privacy” is based on the use of 64-bit or 128-bit keys and the
popular RC4 encryption algorithm. Wireless devices without a valid WEP key are
excluded from network traffic.
