I have been on 20 mb for some time , have you tested you speed yet (mine is about 13/14 meg on a good day) and have you orderd a new modum if you are using the surfe board from motorola, a lot I have read says it's not up to it and that will help get your speed up when changed, they are rolling out new modems but it may take a long time if you dont shout.
