I have a computer with a wireless network adapter which connects to my roughter down stairs and i'm getting a xbox 360 tommorow. I want to hook my 360 up to my pc with an ethernet cable and then get the wireless signal of my pc's wireless adapter. First question is, will this work? Second question is, My internet has 0.5mb upstream and 5.0mb downstream, will this be good enough to play xbox live without lag etc? Thanks in advance!
