I've tried everything. I've done both tuts from above. My 360 and laptop detect each other but I can't share anything. I have opened my ports. What can I do? Does my laptop being on wireless and my XBOX being wired have something to do with it? By the way, my modem has a built in router. Not sure if that matters or not. Some one please help. It would be greatly appreciated. The people at MS customer support always say the same stuff over and over again and nothing they tell me to do/try works.
