What happens when you ping the router?

If you let it ping a long time and see no lost packets then the
connection to the router is happy. Then you can take the MTR
results and stretch your pings out into the network and see where
the packet loss begins. Just go outwards one hop at a time. When
you find the source of the problem you then know who to bother
about it. (The MTR results MAY be indicative of where the problem
lies. And if you put a "-i 5" in the ping any rate limiting will
probably not be triggered.)
