I've just purchased a Linksys wireless gateway and have been trying to get onto XBOX live. This is the first time that I have had broadband, and I have had it for a month, but I have not ever been able to get onto XBOX live. I continually get a message that says that the DNS server is unknown, the MAC address on the system doesn't match the MAC address on the Gateway... I just really don't know what to do. Can anyone help me please?
