Mac Connect to Xbox via Router

Hi guys,

I've seen several threads here (including other forums) regarding how to connect mac (macbook pro) to my xbox via a router but it needs an ethernet cable between mac and xbox.

I have followed instructions below:

But what I have right now is my XBOX IS CONNECTED TO THE ROUTER THROUGH AN ETHERNET CABLE (at my living room) while my MAC is away from both (but still can connect through wireless connection) ...

Is someone familiar with this scenario? Please help!!!

 

I want to connect my Mac to my xbox via wireless internet connection so I can watch movies.

I have read the one below:

it does not work for me though. I am assuming it is because in that site, you need to connect your mac to your xbox via an ethernet cable. the difference in what I have right now is that my xbox is connected to the router instead of the mac.
