Well I recently picked up xbox live. I have a computer in my room connected to the internet via a Linksys Wireless G PCI adapter WMP54GS. A buddy of mine told me to save some money I should just run a cable to my computer and do a shared internet connection with the xbox. I set up what I had to on my computer to have a shared connection and I connected a cross-over ethernet cable from my xbox to my computer. When i tried to boot up xbox live the xbox prompted that there was no connection. Am I missing anything?
