Having (hopefully) now seen the back of speed issues I now come to the question of latency....interleaved or fast. Prior to resolving the problem on my broadband conn I was on Interleved and had a Noise margin of over 30db. I have been left on Interleaved but the Noise was reset to 6 db. It seems fine with the speed currently around 8/9 MB. Even so I am in a quandary as to what to do about latency as the Engineer was adamant that I should request reset to Fast. I see other postings elsewhere saying that Fast can lead to problems. I use the computer purely for Surfing and email. So,what should I do, stay with Interleaved or insist on being switched to Fast?
