Jeff.
If you haven't already, could you run some tests at testmy.net. The instructions on what to do are in the link below. Also, make sure that when you are running the tests, you use a single device connected directly to the modem. NO ROUTER. Also make sure to create the account, run the tests under that account and use the test size described.

Jeff,
Chris is trying to help you, but if you don't answer his questions he can't do so.
The question...Have you been using testmy.net for your requested speed tests?
If so, please post the results page URL. You can do so by signing in to your testmy.net account, click on "Results" and copy, then past the URL into a post on here. It will look like the following, but with your account user name where it says yourusername....
http://testmy.net/quickstats/[yourusername]
This will enable Chris, who is a Rep at the corporate level, to begin helping you.
