Ok so I have everything set up and the Xbox 360 can share the wireless connection on my laptop because i have it wired to the eathernet port on my laptop. My problem is that I cant get my windows media player's file sharing thing to find my Xbox and my xbox cant find my laptop. I've not done this since they updated the Xbox dashboard. I have done about everything i can think of and read numerous simaler forums and no luck. can some one please help me?
