Q. Brian, are You Going to Tell Me To Run the Ethernet Cable From My Xbox All the Way Across My House to My Router?

A. NO!   - Running a cable from your Xbox on one end of the house, under the floor, up through walls and to the router is a WIRED connection, not a wireless connection.

After you implement my method, you'll be able to communicate wirelessly without a hard cable connecting your Xbox to the Router.
