• The wizard is located on the CD-ROM supplied with the Wireless LAN PC Card. Make sure
that your CD-ROM drive is ready for use.
• When using the Wireless LAN PC Card in the Access Point Network connection mode, you
must install the access point and make the necessary settings before proceeding. For details
about these procedures, refer to the documentation provided with your access point.
• To install the supplied software on a computer running the Windows 2000 operating system, log on as a user
listed in "Administrators". To install the supplied software on a computer running the Windows XP operating
system, log on as a user with administrator access privileges. You cannot install the software or modify settings

Computer Firewall Functions
When using the Windows XP "Internet Connection Firewall" function
Enabling the Windows XP "Internet Connection Firewall" function may prevent your
computer from accessing a wireless network. (By default, this function is disabled on
computers running the Windows XP operating system.) If this function is enabled, your
computer may not be able to connect to your network when you change your access point
settings. If this happens, disable the "Internet Connection Firewall" function, connect to the
network, and then re-enable the function. For details, refer to Windows XP Help.
Network security is an important issue. Consider carefully how best to protect your computer.
When using a personal firewall function provided by virus scanning or
network security software
Virus scanning and network security software sometimes includes a function called a
"personal firewall" that prevents illegal access by outside entities. Depending on the
software, the security level of this function may be initially set to a high level. If this high
security level setting is left in effect, it may be impossible for an outside entity to access
your computer. This can cause problems such as not being able to connect to the network
when changing the access point's settings. In this event, lower the security level to permit
the network connection. For details, refer to the documentation provided with your software.
• Pay special attention to security issues.
• For questions regarding firewall functions, contact your firewall software manufacturer.
When using the Wireless LAN PC Card in the Access Point Network connection
mode, turn on the access point.
The Access Point Network connection mode is used when building a network around an access point (sold
separately). The Peer to Peer Network connection mode is used when a network is composed mainly of
computers with wireless capabilities (i.e. that do not need to connect through an access point).
