Hello, as of 10:30 PM cnt 12/18/2013 I have been unable to connect to Xbox live. I ran the test connection and it won't connect to the network. However, I know it is not my internet problem because I am currently typing this on my computer, and my roomate's Xbox is connected to live. I have deleted the profiles and cleared the cache, I hit a snag though when I try to download my profile, because I can't connect to network, but get error code: 80151901. I have noticed several other people are having this problem as well, so before you ask I will go ahead and type the below stuff ahead of time. Like I said, I have tried all posted solutions, and nothing is working. Which is why I am finally posting a thread.
