Bandwidth issue

I installed a balance 20, with wan1 having a bandwidth of 51 Mbs Down/5 up from the modem. I connected just one user through the 20 and my readings were not greater then 30/5 Mbs. ?

Is this a current generation Balance 20? Feel free to start a support ticket by visiting:

Brand new out of the box.
