Broadband speed through the floor

Question

Hello All
Since last Tuesday my Broadband speed has been killed. I was consistently getting arounf 16Mbps (ADSL2) but since last Tuesday it has been averaging less than 1Mbps.
I have been in contact with BT Customer Care, and, in their defence, they have been quite good once I got past the offshore call centre.
Here is what they have done:
- Replaced my trusty BT Voyager 200V with a new Home Hub 3
- Initiated a line reset.
They said the line reset would complete by Friday the 23rd but so far I have seen no improvement. My router is showing the correct line speed as quoted by BT, (Details from the Home Hub copied in below).
You'll notice the line has only been up for 10 minutes. About 20 minutes ago the line dropped and I lost broadband and voice.
So I guess I have a couple of questions if anyone can help me please?
- What does a line reset do
- When would I expect to see an improvement?
Like I say, BT have been quite good about it I just would have expected an improvement by now if it was a line reset that was required.
Nothing has changed in my home equipment wise, except swapping the Voyager out for the Home Hub. I'm not using the Home Hub for wireless as I use an Apple Time Capsule. Locally, the wireless network is fine so it is definately something happening past the router, (as far as I understand anyway!).
Thanks in advance  for any advice!

[EDIT]
I should add that when I used http://speedtester.bt.com this afternoon my download speed was recorded at 750kbps and upload was 1.09Mbps so I could upload quicker than download!!
[EDIT 2]
I have just run http://speedtester.bt.com again and here are the results:
 Download speedachieved during the test was - 1.51 Mbps
 For your connection, the acceptable range of speeds is 4 Mbps-21 Mbps.
 IP Profile for your line is - 18.1 Mbps
Looking on this forum it seems the IP profile for the line could be the key but as you can see mine seems OK, (I think!)
