ADSL2 speeds are determined by many things but one of the major ones is your distance from the exchange. This is not something the provider has any control over. My provider quotes a maximum of 24000kbps and I actually get about 7100kbps. So at top speed when I am downloading something, I see actual speeds up around 700kbps. This, you would agree, is much faster than any 1500kbps connnection I know of (which would see your actual download around 150kbps)!!!
