Hi, did you ever figure out how you did it? I'm having the same problem now, I can't connect my Xbox 360 to the internet

Can somebody help me? I need to connect to Xbox Live, I'm running an ethernet cord from my Xbox to my computer, but I can't figure out how to connect it to Xbox Live. I'm running off of Lucid Puppy 5.2, and I am using a wireless adapter to connect to the internet.
