just saw this on the Amped Wireless Support Page:
Our devices are designed to use distinct SSIDs from the router. It is possible to name the units with the same SSID, but we don't recommend that usage. It makes it very difficult for identification purposes if you need to enter the Amped Device Setup Page.
If you would like to set your router and Amped device with the same SSID, despite our recommendation, this can be done during the setup process. You also want to make sure you use the same password as the router. We do recommend when using the same SSID that you do disable DHCP on the Amped device and set a static IP. This way you will be able to enter the setup page by entering the IP address in the web browser address bar.
