I changed to the 40/20 product yesterday and would happily show you a speed test but can't see an option to add an attachment.
The BT speed test shows an upload profile of 20Mb.

For the BT speed test copy and paste the contents of the two text boxes of results, where you read the upstream IP Profile. (FYI the upstream IP Profile is always the value of the upstream maximum of the product. The downstream IP Profile is 0.9679 of the connection speed).

For the thinkbroadband speed test and the speedtest.net ones, they provide a link you can publish/post for people to click.

How's this:

Download speed achieved during the test was - 37.78 Mbps
For your connection, the acceptable range of speeds is 31.35 Mbps-44.79 Mbps .
Additional Information:
IP Profile for your line is - 44.79 Mbps

Upload speed achieved during the test was - 7.83Mbps
Additional Information:
Upstream Rate IP profile on your line is - 20 Mbps

I think this confirms the PlusNet 40/20 product uses the BT 80/20 product but the download is limited by PlusNet to 40Mb

Yes, but .

We already know this for a fact.

1) As I've already posted, the only products they can buy from BT Openreach and BT Wholesale are 40/2, 40/10 and 80/20, and

2) The quote from the Plusnet Head of Products in this post.

And I was responding to a request on the PlusNet forums by an employee of PlusNet to post a speed test as MrSaffron did not believe what they had told him.
Plusnet forum post

I'd forgotten that, as your immediate reply was of course to me .

Maybe he'll believe us and Plusnet now.

Using the fact that IP Profile = 96.79% (0.9679) of IP Profile, your IP Profile of 44.79 Mbps indicates a sync speed of around 46.28 Mbps.

Either you are actually on 80/20, but your connection can only sync at 46.28 Mbps or that everyone would end up on 80/20, but 'throughput' (not sync speed) is capped (by Plusnet) at 40 Mbps.



What is your Current Line speed (from Plusnet's Member Centre)?

When it worked properly, that would previously have been BT's IP Profile minus 100 kbps.

If it is now exactly 40 Mbps, it would suggest that Plusnet simply 'restrict' the 80/20 service to 40/20 'throughput', regardless of a potentially much higher actual sync speed.


FWIW, I THINK the maximum throughput speed available from Plusnet on a connection in sync at 40 Mbps (39999 Kbps) was 37.5 Mbps.
That would have given a BT IP Profile of around 38.72 Mbps.



I'm with Plusnet, out of contract for quite a few months now.

I am toying with the idea of signing up for the 40/20 product (on contract), because if it is actually a 80/20 service with only throughput restricted, it night cause a DLM reset back to a wide open profile again for my line to stabilise at whatever it can manage.

I was abl;e to achieve up to 35 Mbps sync speed, but can now only achieve 18.7 Mbps sync speed.

That may well be simply due to increased crosstalk, but I've never been 100% sure that DLM was reset with a wide open profile when an engineer visited to investigate my reduced speeds.
Either that or I'm now on a super-stable profile, where sync speed is intentionally reduced to provide stability in preference to speed.

The Current line speed is almost certainly how they have done it. It should be easy to stop it being updated by the auto-system.

(The difficulty is more in getting the auto-system to be reliable LOL).

And they have said that it is 80/20 but slugged.

When I joined PN on 2nd June, they provisioned me on the 40/10, when I wanted 80/20 because of some website screwup. I was on 80/20 with BT Infinity for the previous ~20 months. I managed a maximum download of 38Mbps on the tbb tester. My sync was 39998 / 9526 and there were ZERO errors reported by my HG612 for the few days I was on this profile. The PN website said I was connected at 38Mbps. Since I'd raised an issue, I was then switched to the Openreach 80/20 profile, and now sync at 56013 / 9523 and have around 60 error seconds/hour. The reset of the DLM (in the summer months !) has removed my interleaving and its stayed this way for the last few weeks. Whereas on Infinity I was connected in Sept 2012 and was interleaved from day 2 for the entire time.

That may well be simply due to increased crosstalk, but I've never been 100% sure that DLM was reset with a wide open profile when an engineer visited to investigate my reduced speeds.
Either that or I'm now on a super-stable profile, where sync speed is intentionally reduced to provide stability in preference to speed.

Interesting question, either migrating ISP or migrating product could kick DLM. I would wait until after 1st July when the new ofcom situation kicks in, as after then an ISP shouldn't be charged for migrations (and thus force people to minimum term 18month contracts).

I might as well give it a go then, especially as it'll be unlimited & slightly cheaper than my legacy Value Fibre product.

well remember if your estimate is low plusnet still provision 40/10 on the higher speed packages.

It's rather silly if BT Exchange say IP Profile on the line is 77.42Mbps / 20.00Mbps but throughput of 35Mbps / 17Mbps because of Plusnet capped current high speed of 38Mb if the product does change to 40/20 from 80/20 because they put everyones on 80/20.

I think it should go back to 40/10 and 80/20 both unlimited as there is no point for doing 40/20 on the higher product 80/20 as the local exchange staying at 78Mb to waste all the bandwidth.
