ok, what type of internet service are you subscribed to? Cable, DSL, Satellite...etc?
At those speeds mentioned it would appear you are on DSL if i had to guess, and other than paying for a higher bandwidth service you are as fast as you will get. Of course there will be tweaks and such that you can apply to specific games and apps that will make them run better on a slower connection.
Your connection is pretty slow. For instance my home connection is 45mb down 40mb up and I only pay ~42.99 a month for it in addition to my FIOS Cable bill.
