With your noise margin at 14, there is not much room for improvement!
Orange do not go much lower than 9 and tim and myself are generally around 9.5 to 10.5 and that is with a 12 and 14 meg line respectively.
With only 14, you won't get much squeezed out of your line.
Post all your stats up and we will be able to tell you what your max should be.

No re-syncing today for me so still on 14meg/1.3meg. I'm getting a slight drift downwards from a recent high of 14.8 to 14.2 now.
Had to replace my DGN2000 router as it appeared to be faulty which meant several hours disconnected and prior to replacement several power downs to get it working properly again.
Are these stats basically similar given the difference in the way the two modes operate? Find it strange that the noise margin drops by half and yet the speed is still just the same (1Mb).
Just checked today and found I am now up to 3meg, so gone from 1meg to 2 now 3 in last 2 days.
router stats show noise margin 10db connection speed 3147kbps.
thanks, I'll have a read of that.
Simply though, my question is, given my noise margin on ADSL2+ of ~15db and only syncing at 1Mb, im guessing I wont have much more room for an increase in speed?
Where as on G.DMT where to noise margin is ~29db I have a greater chance of achieving higher speeds. Is this correct?
Is it due to the high frequency range that ADSL2+ operates at that causes my SNR to be lower when on that mode? Meaning that the SNR at the higher frequencies is too low for any bits to be allocated to those subtones?

Until it becomes clear how Orange are manipulating the Target SNR it's very difficult to analyse any of the results. It may be an automatic system like BT's rather than a manual system like BE/o2 (now Sky)'s.
By setting a high Target they can reduce or "cap" if you like, the sync speed.
So in your case if the Target SNR is 15dB that could be why you sync at 1Mb.
If the Target was 6dB you may sync at 3Mb....these are just examples and don't relate to actuality.
The difference on G.DMT is directly related to the lower frequencies that uses. The lower frequencies may pick up less interference that the higher ones, that's why problems are normally noticed on the downstream rather than the upstream.
Thanks so say they did have it set to 15db and I had it on G.DMT then the speed should increase? (As it lowers from 29-15db). Or does that not apply as ADSL2+ has more subtones? So has more to choose from in the case where a high SNR prevents particular subtones from being used.
Interestingly the router shows roughly the same attainable DL rate for both modes (3.8Mb) even given the difference in SNR.
Just to add, still on my new router, no reboots, just a resync by the DLM yet again!!! Why is it bothering!!! What is the point of moving my speed down!!!!!!
No point at all. My line has proved it can handle 12 meg for the last couple of weeks, then we get the super duper DLM thinks it knows better!!!
