address of the machine is allowed in the filter. You can find the MAC address by printing the
Network Configuration Report.
• If you manually entered the Network Name (SSID) and security information (authentication
method/encryption method), the information may be incorrect. Check the Network Name and
security information again and re-enter the correct information.
• Restart your wireless router/access point. If you cannot find the Network Name (SSID) and
security information, see the documentation provided with your wireless router/access point,
or contact the router manufacturer, your system administrator, or Internet service provider.
