I set up all port forwarding and it worked fine for a month and suddenly one day it wouldnt open. I found the problem to be that I had ports forwarded to a specific IP but had not set my xbox to a static IP. I did that last night and played BO smoothly with full bars. I just got off work and cant connect to xbox live. I havent changed any settings and I checked this.I have exhausted almost every source but this one.
