Internet Speed Slow! help?

[Stephen]

fact about ADSL2

Cable Internet providers share bandwidth, so your speed decreases as more users sign up. With ADSL2, speed decreases as the distance from the telephone provider to your residence increases.

The difference with you is that they may all be running off of a RT ( Remote Terminal ) closer than the one you are being fed off of.
I am assuming you have discussed this with the carrier ?
Do you only have the 1 computer ? if you have more what are they getting for speed ? if your friend has a laptop that he knows he gets higher speed on maybe he can test your connection. that way you know his laptop is capable of the higher speed and it narrows it down to your ISP.
