Speed connection loss issue since mid December

Question

Morning all here,
We've been having speed problems since the middle of December. We've  had BT Total broadband since January 2009 with a very consistant and reliable 3-4 Mbps download speed, but since arround the 13th of Dec when we had a 24 hr power cut the line has never recovered. I've had a good look round the forum here re possible solutions and suggestions, tried all the tricks re the Openreach master socket faceplate, new microfilters etc but its not attainng the service we used to have.
Stats and speed test as of this morning attached below, we'd much appreciate it if someone here can have a look. The home hub 2 has been on for about 14 days now, but apeared to loose and reacquire connection on christmas morning. We were away for three days over that period but there was no power failure so it wasnt the route being power cycled.

Answer 1

Thanks for the reply imjolly
I haven't done a quiet line test yet, I was trying to leave the hub online as long as possible over xmas to see if things improved, I had tried the hub in the master socket behind the faceplate, but there was no diference between speed tests with it plugged in there instead of the front faceplate socket or the extension it normaly sits in someplace else in the house.
Interestingly, I've just 5 mins ago spoken to my next door neighbour, he's just had an openreach chap in testing the line not half an hour ago. His homehub has turned out to have been fried during the power outage on the 13th Dec., its running slow and unreliably dropping out now and then. Openreach chap took it apart and you could see the damage to the circuit he said.
Now, where do we go from here, that doesn't involve having to speak to BT India I wonder? Should I have a peak inside our router or make the dreded phone call......aaaggghhhh..
Thanks for you attention again.
