Hi, I am Tammy McClelland. Rockspace Wireless Extender Setup is a router that helps to extend the range of your wireless network by using existing WiFi connections. This device has two modes: Access Point mode and Client Bridge mode. The Access Point mode allows you to use the Rockspace as a WiFi hotspot while the Client Bridge mode allows you to connect other devices to your home network via WiFi. For re.rockspace.local setup, you need to download the Rockspace app on your phone, follow the instructions given in that app and then connect the Rockspace to your computer or laptop using an Ethernet cable.
