How can I prioritize my internet connection so that I am able to get 90% of the bandwidth with a D-Link DSL-2730E Router?

I don't understand your question.

ALL a router does, is connect to the internet and various equipment.  So it already receives all the bandwidth your provider is providing.  If it's not receiving the full bandwidth available, you need a different router - one rated with the full bandwidth capability.
