I wonder if someone at PN could give my connection a kick?
For a while now the current Data Rate has been considerably lower than than the maximum attainable speed shown in my router - by around 3.5 megs!
The line appears to be on a stable maximum attainable rate and the data rate has been much closer to the max previously and I can see the maximum going up again but the connected rate remaining stubborn.
I think you need to be aware that the Max attainable rate is a calculated value that may not actually be achievable in practice. It is known that under certain line conditions, particularly if interleaving is active the attainable rate is grossly over-estimated so can never be achieved. On the other hand my attainable is less than my sync speed but since I have 80/20 sync speeds it doesn't bother me.
