Gizmo, I have never seen software that limits the speed that your computer talks to your modem. With my cable modem I installed no software and don't get any higher speeds. With our DSL service no matter if you install using the included 2 cd's or do it all manually with no software at all, the speeds are the same.
I know my cable company authencates my speed by my modems serial number and location.
With our DSL service its all done with usernames. The lines are all provisioned the same and the speed caps are done on the usernames. But if the great gizmo says thats the way some are, the ninja will accept that as a viable option and humbly apolgize for my error.
