im not sure i understand the question. if i pay for 10mb thats what i receive. whats the difference if it gets to me by dsl or cable?
In the US if you pay for 10mbps that's up to 10mbps.
You may get 1.5, you may get 10.
I had DSL 7mbps and only got 3mbps.
Now I have Cable 7mbps with turbo-boost and typically get 18mbps.
