How do I add a wire to a wireless network using a macbook and an airport base station?

My family switched over to a completely wireless network recently, but that has just brought up a problem for me. I want to play my xbox online, but now I have no wire with which to connect it. I need to figure out how to grab the wireless signal with an airport base station, or some other thing and switch it over to ethernet, my network is now cable based.How do I add a wire to a wireless network using a macbook and an airport base station?
