By HH3 I presume you mean Home Hub 3? This is a Home Hub 2 - I can't seem to find the max attainable line rate on it.

Though I found a calculator online which, based on my downstream attenuation, says it ought to be about 21526 kbps

To answer this, (or rather - fail to), from what I can gather, I don't have a test socket as all of our sockets are LJU rather than NTE5. I'm afraid I don't know what the previous sync rate was. In terms of simple speed, I was getting 5000-6000 kbps if I recall.

Yes, you should get a fast connection if only your noise margin wasn't so high.

Right, I contacted BT who looked into it and said that it's a fault in their network. They hope to fix it within the next 48 hours - I'll report back then.

isp called opal on their business connections automatically drop the sync speeds down to like a 1/4 of a meg when users are experiencing connectivity problems
I know because we a reseller for them and whenever any of our customers experience problems the first thing they do is drop the connection sync right down similar to what this person is experiencing

with the normal internal wiring problem they sync speed and throughput are two different things however with this sync u can see it is sitting at around 256KB

look at his noise margins but his power output is very confusing

Why?

it is zero

And?

cos most adsl connections have a voltage to ensure the DTE receives a signal

he is still a good few km's from the exchange
