Case 4

Cannot establish a connection

• Verify your computer’s firewall functions.

– When using the Windows XP operating system

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.

– When using 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

• Network security is an important issue. You are urged to consider carefully how best to protect your computer.

• For questions regarding firewall functions, please contact your firewall software manufacturer.
