Yes, SNR stands for "Signal to Noise Ratio". On my Vigor 2800 with ADSL+
the SNR is 5.0 as yours, but my attenuation is 18.5 which is by far
better than yours (its a logarithmic scale, smaller values are better,
see e.g., http://www.kitz.co.uk/adsl/linestats.htm,
I'm not a specialist, but I think the high attenuation is your problem.
Best regards,
