I have an original xbox and an airport router that connects 4 macs onto one system. Every time i try to log on to xbox live (I don't have an account yet) it says either, "the gateway is incorrect or the DNS is incorrect" I've enter both of these numbers in correctly because it wouldn't automatically configure them. I just bought a wireless adapter for the xbox and even though it says it works it still won't log on. I've talked to xbox support, earthlink support, and apple support, none of them have helped. I'm out of ideas, someone help me please.
