Had to reboot the router at lunch time in the hope to get the PN profile to match BTs, fortunately for me that did the trick.

PN need to get this mismatching debacle fixed ASAP as it seems to be getting worse from what I'm experiencing of late.

My current BT profile for my line is

Download speedachieved during the test was - 38.22 Mbps
For your connection, the acceptable range of speedsis 12 Mbps-44.99 Mbps .
Additional Information:
IP Profile for your line is - 44.99 Mbps


info from Plusnet

Estimated line speed:
44Mb (Accurate to within +/- 1Mbit) - Checked on 2012-08-26 00:49:43
Current line speed:
39.4 Mb

Rebooting the router doesn't change the profile on our side though?

All I can think of that's happened is that the reboot has forced a resync, which has generated a new line report that was then picked up.

That's interesting - I thought all "line speeds" on the Plusnet side were set to 20Mb, 40Mb or 80Mb for FTTC connections (all of them basically meaning unrestricted) but I see mine is now set to 69.2Mb, which is actually correct (same as my IP profile) but I see yours isn't.

That was changed when the 80/20 product ceased to be a trial and now it is supposed to work the same as ADSL2+

Thanks, I hadn't spotted that. I suppose I'd better keep an eye on it now!

OK, so if the IP profile from the BT performance tester says 3.5Mbps what's stopping the throughput increasing after the rise in IP profile? (it increases OK after a reboot with the same 4Meg sync speed)

You are saying/suggesting a new line report could be the issue, why wasn't the increase in IP profile picked up when it increased from whatever it was previously (2.5Meg?) to 3.5Meg as it used to happen automatically and what or whose equipment/systems is not picking it up?

This is being discussed ad nauseum in the Plusnet forums and many of us are suffering.
There doesn't appear to be a single reason but the end result is that the Delta reports from BT are not working as they should and, in my opinion it could be the problem of having two different profile generating systems in BT and they are not producing a correct result.
In my case when I was on 20CN for a small drop in speed it changed the IP profile almost immediately but a small increase in speed took up to 3 days to take effect. This is as it was supposed to operate.
Now I am on 21CN the IP profile I see from a BT speedtest changes immediately (up or down) but the Delta reports seem to follow the old timing - immediate for a drop and 2-3 days for an increase.
In addition when I compared my connection speed changes with the ones received by Plusnet from BT not only had they missed a chunk of them but had even added a spurious one as well.
So it has all the hallmarks of a right mess but fortunately my sync speed only changes by about 300kbps (best to worst) so I can live with it.

It has luckily never affected madasafish customers hence why I am still not swapping to a plusnet tariff.on my adsl2 line

In reply to a post by camieabz:

The profile keeps in step for me, but the (stable) sync can be anything from 15,000 to 15,500 and one of the reasons I listed is causing the sync issues.

Shouldn't we look at what causes sync to change to prevent profile changes, rather than fix the profile issues?

No. The OP is discussing a specific issue which highlights a quite disconcerting issue with Plusnet's traffic management system.
