Overview  
What you can do with your Wireless LAN PC Card  
You can build a wireless LAN using the Wireless LAN PC Card PCWA-  
C150S (subsequently referred to as “Wireless LAN PC Card”). Equipping  
multiple computers with Wireless LAN PC Cards and installing the  
supplied software enables the computers to communicate and exchange  
data without a physical connection.  
There are two basic configuration modes for a wireless LAN. In  
“Infrastructure Mode”, communication is routed through a separately  
available 2.4 GHz Wireless LAN Access Point (subsequently referred to as  
“Access Point”). In “Peer-to-Peer Mode”, no Access Point is used and the  
computers communicate directly with each other. If you connect your  
Access Point to a communication device (such as a cable modem, DSL  
modem, broadband router or ISDN router) or wired Ethernet LAN with an  
Internet connection, the computers in the wireless LAN can access the  
Internet.  
Note  
This product is a 2.4 GHz Wireless LAN PC Card conforming to the IEEE  
802.11b standard. It is not compatible with products conforming to other  
standards (such as the IEEE 802.11a standard for 5 GHz wireless LANs).  
z Tips  
- For details regarding functions and operation of the Access Point, please refer to its  
documentation.  
- For information about file and printer sharing in a network environment, see Windows  
Help.

About the supplied software  
The Wireless LAN PC Card comes with the following software.  
Client Manager  
Client Manager is utility software for displaying the communication status  
of the Wireless LAN PC Card.  
Usually, the software operates in the background and shows the  
communication status using an icon in the system tray (notification area in  
Windows XP). In operating systems other than Windows XP, the Client  
Manager allows you to change network settings of the computer and to  
switch networks.  
Basic procedures for using Client Manager are explained in this manual.  
PCWA-C150S Wireless LAN PC Card Driver

Establishing communication with the Access Point  
This section describes how to configure settings for communication with an  
Access Point. When not using an Access Point, see “Configuring  
communication settings for Peer-to-Peer Mode” on page 40.  
Before configuring the settings, the following tasks must be  
completed:  
• The Wireless LAN PC Card must be inserted into the computer.  
• The Access Point and the computer with the Wireless LAN PC Card  
must be located within the communication limits of the Access Point  
(approx. 330 feet), and the Access Point must be turned on. For details,  
see the Access Point documentation.  
• Check the Network Name (also called SSID) and the Data Security (also  
called WEP or Encryption) settings of the Access Point. For details about  
these settings, consult your network administrator. The factory-settings  
for the Access Point are listed in the Access Point documentation.

Verify that Access Point is selected in the “Network Type”  
list, and click “Next”.  
The Identify Your Network window shown below appears.  
5 In the “Network Name” field, enter the same Network Name  
as set for the Access Point. You can also click “Scan” to  
search for Access Points within communication range.  
Note  
The Network Name is case sensitive. Be sure to use the same uppercase/lowercase  
spelling as at the Access Point.  
z Tips  
• If you leave the Network Name field blank, the computer will attempt to connect  
to an arbitrary Access Point within range. If you enter “ANY” (all in uppercase) in  
the Network Name field, the computer will attempt to connect to all Access Points  
within range.  
• If the “Scan” button is dimmed, an Access Point search cannot be performed.  
Enter the Network Name set for the Access Point.

checked that communication can be established. For details about changing the  
settings of the Access Point, see the documentation of the Access Point. After  
changing the settings of the Access Point, use Client Manager to change the  
settings for the Wireless LAN PC Card accordingly.

Hexadecimal (0 - 9, a - f, A - F)”. Symbols are also available  
when you select “Alphanumeric Characters (0-9, a-z, A-Z)”.  
Note  
If the Access Point still uses the factory default key, it is strongly recommended  
that you change it after having checked that communication can be established.  
After changing the settings of the Access Point, use Client Manager to change  
the settings for the Wireless LAN PC Card accordingly. For details about

Glossary  
Channel number  
The frequency used for wireless  
communications. Wireless  
communications are possible only among  
client computers and Access Points that  
use the same channel.  
Data Security  
IEEE 802.11 compliant security system  
(also called WEP or Encryption). Using  
the encryption key as the password, only  
client computers and Access Points that  
have the same key may log onto the same  
wireless LAN.  
Encryption key  
See Data Security  
LAN (Local Area Network)  
A network which is accessible only to its  
members, unlike the Internet, which is  
open to an unlimited number of people. A  
LAN may be built for different purposes.  
For example, you can build an office LAN  
that is accessible only to members of the  
same department or a home LAN that is  
accessible only to family members.  
TCP/IP (Transmission Control  
Protocol/Internet Protocol)  
TCP/IP is a networking protocol, a  
common set of communications standards  
that allow computers to communicate with  
each other. Because the Internet uses TCP/  
IP, a computer can only connect to the  
Internet when the TCP/IP protocol is  
installed on it.

11 Mbps is a theoretical value. Under real-world conditions,  
transfer rate will normally be in the range of 4 - 5 Mbps. This  
is true for all IEEE 802.11b compliant systems. The  
bandwidth available with wireless communications may not  
be sufficient for high-volume streaming data such as  
MPEG2.  
Transfer rate is 11  
Mbps, but MPEG2  
data does not transfer  
without interruption.  
The actual communication distance depends on various  
factors such as installation site conditions, presence of  
obstacles, and so on.  
Communication fails  
although the computer  
is located within 100  
m (330 feet) of the  
Access Point.  
c Move the computer closer to the Access Point.  
Link test results in  
many dropped  
messages.  
The Access Point and the computer are too far apart.  
c Move the computer closer to the Access Point.  
File transfer is in progress on the network.  
c During transfer of large files, performance may  
temporarily drop. Repeat the test when the network is not  
being used for file transfer.  
There is radio interference.  
c If there is another wireless station nearby using the same  
channel, try changing the channel number.  
c If a Bluetooth-enabled wireless device is being used  
nearby, stop using it at the same time.  
A microwave oven is being used nearby.  
c A microwave oven may also have an adverse effect on  
communication performance. Do not use it at the same  
time.  
Notes  
When more than 2% of messages are dropped,  
communication performance will be seriously affected. At  
5% and higher, most network applications will have  
trouble functioning.  
Perform the link test for at least 1 minute continuously  
(minimum 200 messages) to ensure meaningful results.
