I have a modem and I have connected to xbox live before. My PC is downstairs and by modem is connected directly into the wall. My grandmother is always watching T.V. in the living room. Therefore i have to wait for hours till she goes some where so that I can bring my xbox 360 downstairs and play it. I don’t wanna buy the wireless adapter and I don’t have a pc or wireless router. If my 360 is up stairs how can I connect without running the cable through my entire house(its not long enough to reach my room from its location). Please help and thx!
