Start of problem: 1/22/13 , i have never experienced this before
Exact Issue: When playing Call of Duty : Black Ops 2, i can connect to the multiplayer service, i can connect to a public match, and begin playing. I can typically make it through a round, and then get booted from the server. It shows "Host Disconnected", and then the game becomes responsive, finally kicking me out to the load screen where it says that i need to be logged into XBOX Live to be logged in. At this point, XBOX messaging pops up to tell me that i have lost my connection with XBOX Live. I try to re-Connect to XBOX Live and am unable to. I then take the recommendation to test my connection. I run a test and am able to connect. I log back in, and can re-start the whole process, only to be disconnected in the same manner again. While this is happening, i have an internet connection the entire time (verified by doing a continuous ping on my laptop).
