I was going to mention that the Hlog does not seem match the attenuation I had seen previously on your old modem. But it is worth noting that modems sometimes have a small margin of difference when reporting the attenuation and some don't even report a figure at all (or at least not in the browser interface, but in the CLI they may). Since I have never owned a D-Link 3782, I cannot comment on what the general differences are between it and other modems when it comes to reporting the attenuation. I did a calculation for your first downstream band's Hlog and I got -10.51, so perhaps the D-Link only calculates the attenuation for the first band that it reports in the interface (which was 8.2 dB in an earlier screenshot)?
Just out of curiosity, what does "adsl info --pbParams" give you?
Regardless, your line appears to be very healthy and you should be able to attain the full 80/20. You should not be concerned by the attenuation being reported as 14 dB unless it impacts your broadband performance.
Don't spit on the cabinet, otherwise the DLM will curse your line eternally.
