I have had a Xbox 360 for 3 years. I know it pretty well, but I have only just tried to use it for Live when Halo 3 came out. I have the 360 premium package, which I thought had a built in wireless adapter that would sync up to my house's wireless internet connection. I cant seem to get it to work. I am correct in assuming the premium has a adapter that can feed off my router like a laptop can, right? I am looking foreward to playing online and hope someone has the answer that can help me. I hope to God the answer is that I have to buy an adapter.
