Broadband Speed dropped and wont come back

Question

Hi, I need help and advice please.
Background info first though, so please bare with me.
During last July 2011 I was fed up of very low speeds and managed to get a BT engineer out to check the wiring etc... He did a great job by finding a badly insulated cable between myself and the Cabinet in our village. He also changed our master socket to a newer version.
Over the next few days my broadband speed went from 0.74mb download to 1.95mb download. Fantastic!
This speed has pretty much been a consistent rarely dropping below 1.7mb and at times has even gone up to my highest recorded of 2.46mb. I thought this was brilliant, I could watch iPlayer no problems and xbox live was even bearable (most of the time).
The big problem where I live is sometimes we have power cuts. Sometimes lasting hours but mainly just for seconds. Even so it switches the BB router off. (I know, but not my fault)
When we had the freak snow fall the other month problems started to raise their head. The computers in the household found issues connecting to the router and to resolve this BT BB Helpdesk kept advising me to reset router to enable connection. After connecting new ADSL filters the speed returned but connection issues continued.
BT supplied me with a brand new home hub 3 which I connected thinking it would give me my 2.4mb speeds again. Oh No. To be fare I think I was getting 1.95mb but I wanted more, as most people would. Why cant I get 2.4mb most of the time I have had for a few months.
Anyway I contacted BT who were kind enough to send a BT engineer out. He Said to me the Broadband speed is put out at the exchange (4.5km) at 8mb and comes into our village at between 3mb and 4mb. He detected no fault on the lines and spent the next 3 hours renewing 'D' and 'E' I think side of cabling (found this out later). He mentioned the noise was high but did something to lower it. On leaving he said I had 2.5mb and was confidant it would rise to 3mb.
Great not drastic but should give me 250kbs to 50kbs extra.
The day he was at my house we had 2 short power cuts followed by another couple some days later. This has not helped I'm sure.
NOW TO THE ISSUE.
My download speed since that day has not gone above 1.46mb download and every time I speak to the call centre they tell me my line is only capable of 2mb therefore 1.46mb is within acceptable range.
I am so tired of explaining that I was capable of receiving 2.4mb some 2 months ago yet now since the new hub 3 and line fiddling I am only capable of a 2mb downstream - 1.46mb DLS.
I know I have to wait 3 - 10 days but with power cuts its a nightmare, and they are so adamant about my 2mb downstream limit What the hell has happened.
Here is a link to my recorded (Speedtest.net) data over the past 11 months showing actual proof of receiving 2.46mb:

Please Help me I know I've had better than this but all the numbers point to the fact I can no longer have them. Why?
Many thanks

Hi JONNYYOUNG,
I'm not educated enough to help but it mat reassure you, as it did me, to know your circumstances are not unique.
Your story sounds very simialr to my experiende last November, speeds and line length being very similar.  An engineer said there was noise on my line so he switched me to another pair.  Did the engineer do that for you too ? Net result my speed dropped from ~2.3 to ~1.4Mbps. 
Fortunately a 21CN upgrade at my excahnge has brought my speed back up to ~2.4Mbps.
I'm sure imjolly, john46 and maybe a mod if you need it will sort you out as well as they did me.
Good luck,
