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