BrokenChameleon: well these are my line stats atm
and i worked it out with attenuation(6.3) devided by 13.81 which gives you the approximate length in Kms i understand that there are many more factors that can affect attenuation also
You can't compare adsl and vdsl attenuation. And so using that attenuation result to estimate distance won't work too.
also 17a gives higher attenuation but faster speeds.
Regardless your line seems to be hitting thw download cap, and you have INP 1 on, and seemingly a 12db snr margin. so if you had 9db snr margin and INP off your atatinable would probably go even higher. your snr would stay the same on down as you're capped, but you may be able to hit 50 megabit for upload.
it's curious that your download speed through your isp isn't a little higher though, although you are seemingly a distance from auckland, so maybe when the ping goes down your speeds will go up a little. (i'd estimate more like 94 megabit for including overheads)
