Long term ADSL issues

Question

Hi guys, looking for a little advice. I live in a fairly rural area, and for nearly a year and a half now I have been battling with constant disconnects, speed changes etc. on my broadband line.
Open reach have been out to the property several times, always locate and fix a minor fault on the line somewhere and then report back to BT that the problem is fixed. A couple of days later...
Anyway - I'm not sure if my line is totally at fault here, which is why I'm posting in the broadband section. This past week, my dowload speed has been less than 1Mb, despite my line averaging 2.5ish and able to hit 4 if I'm lucky.
A quick check on the wholesale speedchecker shows my IP profile is 1.01, and:
"For your connection, the acceptable range of speeds is 0.4 Mbps-1 Mbps."
This used to show 4.
My current router stats are as follows:
ADSL Line Status

18 hours since I was told to reset my home hub - the line has been up longer than that. 
A call to customer services had me testing ethernet ports on my router, and checking to see "if I could go online", which was irrelevant to the problem. I'm not sure if the person I spoke too quite grasped the issue clearly. This long cycle of asking customer services for help, assurances that the speed will improve etc is getting really quite wearing. I understand that at the end of a rural copper wire I can't expect massive bandwidth, but I know my line can comfortably manage more than I'm receiving.
I also know that I'm being fobbed off by call centre robots following a script which doesn't quite fit the problem in hand.
Sorry to complain - I'm just not sure what the next step is. It's probably the line, but that performs sufficiently well to operate a phone. Bad weather causes noticable noise on it though, so I suspect one or two bad joints somewhere. They never manifest themselves when an engineer is here though!
