Issues getting the full speed for the gigablast

I'm having the same problem, I can't get over 450 on my gigablast connection.  Tried The whole home and have tried their standard modem with my own router.  No change.  So I know it's not me, it's not my hardware and not their hardware.  It's the service.

But my problem is I'm afraid to drop below that service, as I would expect to get about 1/2 of it as well.  Might as well be on DSL instead of cable.

it's been this way for over a year, and all they say is a year old post that they are working on it.  I have to think they aren't, they don't care; they think we won't leave for another.  Once I get anything else in my neighborhood; I'm dropping COX like a cheap date.

My PC is hooked in via ethernet and my laptop uses WiFi, same issue. regardless of connection.
