The title basically says it all, I turned my Xbox off about 8 hours ago (Was playing just fine, no errors), and I went to sign in this morning and it dropped me from Xbox Live altogether. I've had my Xbox for over 2 years and have NEVER encountered any connection errors, which is why this situation has me baffled. I went to the Xbox Live Connection troubleshooting, and I did every step possible, and still no solution.
I get the "X" - when I go to test my Xbox Live Connection - between "Xbox 360" and "My Network".
I've unplugged and restarted both my modem and my router, nothing.
I'm ready to call customer support because this is ridiculous, does anyone have any suggestions?
