So I get pretty decent Internet connection speeds, but the router I was provided by the cable company is pretty shocking for WiFi coverage across the house. My office is in the opposite corner of the house, making the WiFi speeds almost unusable. I do have a Powerline adapter, giving me one ethernet connection in the room, currently being used for the Apple TV. Does anyone know if it is possible to share the ethernet connection from the ATV (3rd gen) via micro USB to my rMBP which doesn't have an ethernet jack. I'm just trying to see if it is possible before spending on switches and adapters that would be necessary to connect both devices. Basically, can I share internet through USB in the same way as an iPhone tethering, but using an Apple TV? Thanks for the help, Sam.
