In the Wireless NdxConfiguration Utility, ensure that you are connecting to the correct Wireless Ndx Router by verifying the MAC address, Network name (SSID), and security settings. The MAC address is located on the label on the bottom of the Wireless Ndx Router. Ensure that the correct Pass phrase and encryption option are being used. If you changed the settings in the configuration of the Wireless Ndx Router, you must also change the settings of every Wireless Ndx PC Card or PCI Adapter connecting to this network. The settings of the Wireless Ndx PC Card or PCI Adapter must match the new settings of the Wireless Ndx Router.
