I had interleaving removed last week and connection was stable until the phone line fault, but since last Friday till last night the system re-added interleaving and increased the SNR to 15 from 6.
I had hoped as I am on 21CN, waiting 3 hours would be enough to start the trickle back to what my connection was like pre phone fault for the first reboot, but I have rebooted 2 times since leaving at least an hour between them to get an increase and no change. Normally I would always connect on ADSL2+ but can't since the phone fault so horrible feeling of banded

Glad to see that the phone fault has been fixed all the same.

ADSL2
SNR 15
3000 kbps up / 444 kbps down
with a IP Profile 2.65 Mbps
before Friday it was
ADSL2+
SNR 6
4800-5000/440k
5.1k IP profile
Upload isn't uncapped which I don't need or want with the length of my line.

The quick fix is a line reset

The loop loss looks quite high for the speeds you're receiving at the moment and that may be what's pushed the connection over to ADSL2, as that the main factors in this are the router and the exchange do you have another router you could try? I'd just be interested to see if the stats look any different were I to run another test.

This is the screen grab for DMT on my connection
Note that frequencies above about 850kHz are not being used because of the attenuation effect in the higher frequency band
The difference between ADSL2 and ADSL2+ is that ADSL2 maximum frequency is 1.1MHz and the ADSL2+ maximum frequency is 2.2MHz
Does your router report your attenuation

When I changed my Netgear DG834G v4 (Broadcom chipset) for a DG834Gv5 ( Conexant chipset) I lost about 500kbps speed so it went back to Amazon
Note that my present speeds are with a 5dB default noise margin (I tweaked it down from 6dB)
Noise Margin: 4.8 dB
Connection Rate: 4928 Kbps
Line Attenuation: 51.0 dB
One other thing - you will see that my upload speed is 448kbps and this is because I am on ADSL1 on 21CN as on ADSL2 uncapped upstream I lost 200 - 300 kbps downstream speed and the line became unstable so I switched back
