Refer to Windows XP Help for details about the “Internet Connection Firewall” function.
Note
Make sure that you take appropriate security measures when the “Internet Connection Firewall” function is
disabled. Except when configuring the Access Point, it is strongly recommended that you enable the “Internet
Connection Firewall” function at all times.
■ When using a personal firewall software provided standalone
or as part of an antivirus or network security software
Antivirus scanning and network security software sometimes includes a function called a
“personal firewall”, intended to prevent unauthorized access by other computers. Depending on
the software, the security level of this function may initially be set to a high level. If this high
security level setting is left enabled, other computers may be unable to access your computer. This
can cause problems such as not being able to connect to the network when changing the Wireless
LAN Converter or Access Point settings. In this event, lower the security level to allow the
network connection. Refer to the software instructions or Help for details.
Notes
• Make sure that you take appropriate security measures.
