79/19 slower month after month
This post was on reply to Gandalf but has been deleted 
So I repost it here as a new thread.
Hi Gandalf, thanks again for your reply.
I've put some data together to raise a fault with some data at hand. (Despite more that a fault seems a reduction by design).
I've turned off everything in the house, connected to the master socket, PC with Linux connected via LAN cable directly to the router (and no any other cables), tested with different speedometers online and at different times. My top speed is 47/13 but generally is more like 44/12.
Looking at both the hub one wan log and my previous tests with speedtest, I can clearly see that, with the same SNR I had a faster fibre months ago than now.
E.g on speedtester

Even via wifi and without using the master socket I had a faster fibre than now.

It's the esternal line + some (imposed?) limitation due to much overselling?
From the Hub One Wan logs:

Let's skip some rows... Septemper still ok

The decline....

Basically from 52.2/15.3 at 6dB I'm now at 49.6/14.9 at 6dB. But that's only the connection speed and here comes the possible clue: while before at 52 of connection speed corresponded a 50/51 of real speed, now at 49.6 corresponds a 45 of real speed (and that's not because of viruses, etc., it is tested with Linux from the master socket alone, via Lan).
So there is surely a problem somewhere on the road that has eaten 3mbit, but more than that, there is also something bound to some limitation of traffic. Maybe BT has given Plusnet a second role with less band/traffic available to share? That whould explain why, despite a bit of loss of quality on the line there is no comparable small loss of real speed.
Online I used to have this everyday http://www.speedtest.net/result/5483810162
and now this is one of the top I have at times http://www.speedtest.net/result/7319995297
with any speedometers of the world. Despite the router connects more or less almost at the same speed.
What would happen if I scale down to a 38/9 contract? Theoretically I should really have a better value for money of real 38/9 because this line proves to reach at least 44/12... but I suppose that if I scale down I will get less than 38/9 for the same reason I should now have at least 49/14 but I get 45/12 because the problem is probably not only the line but too much oversell resulting in too much sharing of a limited capacity of the Plusnet network.... could it be the case?
Hello @riccardo2
It looks like your previous thread is still open and I have asked the moderators to merge them.
If you have run through the steps outlined here by , we would recommend you report a fault over at http://faults.plus.net,
so we can investigate this further.
