When I used to live way out in the country(no cable would come out that far) we had signed for dsl and were the last house in the telephone line that could receive dsl. It used to go through swings like that all the time, around 4 in the morning though it would always be blazing fast, so I always just attributed the swings to be from other people on dsl inline before us and when my parents were on the phone it would also slow down(choke at the filters?) I don't know if thats what your issue is, but who knows. Bring up you command prompt when you see that the internet is being slow and look for processes that have a high CPU of Mem usage.
