Ok i recently purchased an ethernet cable cord and i plugged it inot the back of my 360 and my laptop. I dont have wireless internet but i was wondering if i was online at the time the ethernet cable cord is plugged in will i still be able to connet to xbox live. i am able to put music , pictures , and videos on my 360 that come from my laptop. Every time i try to connect to xbox live i always get a "failed" by the IP Address spot. Help Please
