I find it a bit strange that you get a request time out on your first hop, that could be where the issue is as that is clearly unique to you and not any other clients. Have you tried to connect your computer directly to the modem.

Unfortunately, non of the tracert you supplied contained the high ping your complaining about. If you do get one that contains high ping you will then instantly know at what point it is occurring. Note that not counting the request time out you enter the data center in 2 hops.
