  If your wireless network device isn't being recognized by your network when using a Cisco Extender, first ensure the wireless device and its networking are turned on. Positioning the extender closer to the wireless device might help. Also, try to avoid obstructions like metal cabinets or thick walls between the extender and the wireless device. If you have advanced security settings enabled, verify that all adapters on the Powerline network are configured with the same network password.
