Computer Firewall Functions
When using the Windows XP “Internet Connection Firewall” function
Enabling the Windows XP “Internet Connection Firewall” function may prevent
you from being able to access your computer through wireless communication. (This
function is inactive under the Windows XP operating system default settings.)
Because of this function, you may not be able to connect to your network when you
change your Access Point settings. If this happens, deactivate the “Internet
Connection Firewall” function, connect to the network, and then reactivate the
function. For details, refer to Windows XP Help.
Note
Network security is an important issue. You are urged to 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 is designed to prevent 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 in order to permit the network connection. For
details, refer to the manuals provided with your software.
Notes
• Pay special attention to security issues.
• For questions regarding firewall functions, please contact your firewall software manufacturer.
