Because the 40/20 is provided by Openreach 80/20 and capped (if working correctly) to 40 Mbps by the Plusnet Current line speed. That's why it was a non-sustainable product, as they paid Openreach for 80/20 and charged for 40/10.

Because it is the 80/20 OR product it sync's as if sold as 80/20. There is no Openreach 40/20 product.

This is why the CLS figure is required from the OP. It should be 40Mbps. If it is 21Mbps then "summat's oop". As they say in the foreign country immediately to the east of the Pennines.

Just to confirm this, I'm on 40/20 and here are my router stats. With apologies for mangy formatiing as I simply copied and pasted the the table.

Upstream Downstream
Current Rate (Kbps) 19999 79997
Max Rate (Kbps) 28197 80903
SNR Margin (dB) 14.4 5.7
Line Attenuation (dB) 12.8 12.6
Errors (Pkts) 0 0

Yes, I know all that, but I thought what was posted originally was a speed test result.

And I didn't spot the speedtest.net result he gives is in his sig, not the post body . We need to see a current one.

At the moment it's completely unclear what the OP is on about.

Yes, we know how 40/20 works.

What we don't know are the answers to our questions to the OP, who we suspect doesn't. Not helped by having a February 2015 speed test in their sig, which confused me at first, and a strange 22 Megabyte file size figure for no apparent reason that can't be a speed even if we add "per second" to it.

I vaguely remember (from when 80Mb/s was originally being trialled) that Plusnet had a 'special' profile (basically unthrottled, no profile restriction at the Plunset end at all), I think (but can't be 100% sure now) that this used to be shown as 21Mb/s in the member centre 'Current Line Speed'.

[Edit - spelling]

That does sound vaguely familiar and could conceivably explain the phenomenon.

And to me.

My mate got 40/20 with plusnet and his current line speed was set at 78Mb as his router but he keeping it quiet himself as Plusnet didn't changed his current line speed for 7 months now. Lucky him.
