Your downstream noise margin is very high hence the low sync,
As long as you are sure that the problem is not your own internal wiring or equipment then tell BT that the problem has only recently occured and that you are not happy.
I note you are are on ADSL2+.
We recently were upgraded onto the ADSL2+ and had problems from day one. It took 4 visits before it got soughted. Our problem at the end was BT;s exchange equipment and the DLM capping our line for no reason.
Just be polite and if your connection does not improve keep telling them your not happy.
The last engineer to visit us told me that they have had software problems with the exchange equipment on the CN21 product on some lines.
And finally when they call you back after 24hrs for an update and to close the ticket just tell them that you would like to keep it open for 5 days for yourself to monitor. Only when you are happy call them to close the ticket.
Your 2.2M sync is very similar to what i was experiencing when my line was being capped by the BT equipment for no apparent reason. Dont be fobbed off remind them that you had a 12meg sync for 18 months prior to this recent problem.
