Hi, This is Natalie Mitzel. Rockspace wifi extender setup is a process that helps you to extend the range of your WiFi signal. It works with any modem or router and makes it possible to share an Internet connection. Rockspace WiFi extender setup allows you to connect more devices by extending the WiFi signal. The Rockspace extender has two modes: WPS and manual mode. In WPS mode, you can set up your device within seconds by simply pressing the button on your Rockspace extender. In manual mode, you must manually enter the password for your router in order to set up your Rockspace extender.
