This is actually a wireless extender. It acquires the signal from other WiFi enabled device (usually a router) and it broadcasts it even further. To configure it, connect a network cable between your computer and the device and wait a few seconds. Once the IP has been acquired, go to Start > CMD and then type ipconfig /all. Scroll down to the Default Gateway and note the IP somewhere. Paste that IP into the browser then you can access the configuration interface and configure various settings.
