It is possible that you are misunderstanding the function of the device you link to. (It is also 
possible that I am misunderstanding it!)

 From my reading of the very sketchy description, this device is designed for locations where a WiFi 
signal is poor or non-existent. Therefore, I would think that all it has is a mini-WiFi access point 
from which the Chromecast can get a local signal.

It won't be sending Ethernet up the power cable, if that's what you assumed.
