Broadband speeds and packet loss?

I am on an 8 meg connection with sky and am currently getting 3.5megs, which i am happy with, but there seems to be an awful lot of packet loss, between 10-14%. does anybody have any clues to why this may be? thanks
Answer
Traditional connections such as through bt are not made to cope with broadband which is why you get such a high packet loss. the only way to get anywhere near to your full connection speed is to get your broadband through a cable company such as ntl.
