You are still on an SNR of 10.3, this can go much lower, but it looks like you have reached the maximum of the adjustment on your router (they can only influence it a certain amount).
It needs resetting at the DLM back to 6, which would equate to a sync of around 2300-2400K, it may then train back to the 8 or so which you were running before which would drop it back to the 2250 odd.

The problem with that is that eventually the line will vary enough for DLM to kick it back to a 12 or 15dB profile and the process starts all over again!
Typically it'll take about 14 days of the line being stable for DLM to set the profile to a lower SNR, but it'll intervene to raise the SNR within a day or so (depending how 'unstable') the line is being.
Was about to say that...

Why is that shocking? So, it's a long line and it's clearly why the OP can only sync at approx 2mb in the first place!

His line has been stable for a long time at 8-9, h has now manually manipulated it to 10 where it is proving stable. The line issues appear to have passed for the time being, resetting it to 6 will see it train back to it's previous long term setting in all likelyhood.
The DLM will lower the snr automatically yes, but as you indicate it will take a good couple of weeks between alterations. This is why fox needs to have it manually reset. I have been through this time and time again at my old property.
Its probably a bit late in terms of your "time left" living at your parents, but you can actually pay to have the line re-routed to a different exchange. The process is called an "out of area" line installation. My parents had a load of quotes drawn up for this very process years ago, as the Henley exchange was upgraded many years before Wargrave yet was still in range for ADSL.
Probably useless but it may be worth querying BT re that if there really is a much better exchange available and you are likely to stay for a decent length of time.

This is what I used to use for my poor line, before it sadly died.
Bought a DrayTek and so far it's holding out well also. With the DrayTek or 2Wire I was/am able to hold between 2.4 - 2.7Mb.
Like Fox, I am at the very edge of the cut of point for the exchange I connect to, but manage to hold this speed with 58dB loop attenuation and 5dB SNR Margin.I've tried most things to help, ADSLnation filtered faceplate on the Master Socket. I've put the Router away from Phones and the likes, and also run a shielded ADSL cable. The biggest thing that helped was getting on to my ISP and getting BT out to replace the overhead line to the property. They also checked the line all the way back to the exchange and found breaks, which they told me they've fixed, as when it rained the speed used to drop right off. (Moisture getting in?).
Anyway, I ramble on.
