Thought I'd stick with this thread as this is relevant.
We just had a half hour power cut (whole area: network fault).
The router re-synced and I checked the stats which show a new, higher sync rate down, and only 2.3-2.6 SNR down:
DMT Status No Defect
Operational Mode ADSL2+
Upstream 1087
Downstream 8652
SNR Margin(Upstream) 5.7
SNR Margin(Downstream) 2.3
Line Attenuation(Upstream) 22.7
Line Attenuation(Downstream) 45.5
Then I did a couple of Speedtests: 7.41 & 7.50 (up from the previous 6.7 after ADSL2+ upgrade)
Then I did a BT test:
Download Speed
4636 Kbps
0 Kbps 7150 Kbps
Max Achievable Speed
Download speed achieved during the test was - 4636 Kbps
For your connection, the acceptable range of speeds is 2000-7150 Kbps.
Additional Information:
Your DSL Connection Rate :8652 Kbps(DOWN-STREAM), 1087 Kbps(UP-STREAM)
IP Profile for your line is - 7633 Kbps
2. Upstream Test: -provides background information.
Upload Speed
901 Kbps
0 Kbps 1087 Kbps
Max Achievable Speed
>Upload speed achieved during the test was - 901 Kbps
Additional Information:
Upstream Rate IP profile on your line is - 1087 Kbps
That down speed did not tally with any of four online speed tests done on two different sites. Lowest of the four was 7.4

So, apart from the difference between the speedtest results and the BT test, is that down SNR of around 2.4 OK?
Perhaps I should do another BT test tomorrow.
