I need help connecting to Xbox Live. I have the cable running from my Box to desktop, but it will not let me connect? I have a wireless modem/router thing and I have internet on that for my PC, but not for my Xbox? My wired connection says: Local area connection 3 Speed: 100 MBPS Satus: Limited or no connectivity. What do I do? And PLEASE don’t send me to the Xbox help page.it’s useless.
