It is not my internet, if it was it wouldn't affect so many other things and plus my internet on all of my other devices is fine and unaffected.
My Xbox runs off of my 120gb Hard drive and a 4 gb USB. I have tried running it off of one or the other and the lag is still there. If I run it off of my USB it's even slower than it was before.
Can anyone tell me what I can possibly do to fix this problem, I would buy a new Xbox but I don't have the money and that won't be an option for a couple of weeks.
