the usual old hogwash!! ,
When we went to Plusnet ... our usual 4-5 on an 8mb line jumped to 7.9 so close enuf!!
But now on NEW fibre why is there a very similar situation, we should be getting 40 instead get varying speeds up to a max of 37-38 depending on the wind direction.?
No Excuses should really cut it any more as we do have the option of 76 on our line ? . so why is 40 not 40 ?
Also the Fiber Router's Wifi will randomly stop working, LAN is OK , and the router needs a number of power cycles to start up again.
Also the range is very poor compared to the previous P-Net BB Router,.

At any given moment in the universe many things happen. Coincidence is a matter of how close these events are in space, time and relationship.

Say you are getting 3 or 4 Mb/s download on Fibre is that ok ?
What it should say is that the minimum speed on fibre would be X.
It 's hardly fair that fibre users, of which I am one are getting lower speeds than someone on ASDL.
The Daily Mail claim that if services offered are not provided then contracts can be considered null and void

Unless I misread or misunderstood something?

The 40/20 package will only give you up to 38Mbps due to many factors, for example; protocol overheads. This applies to the 80/20 package as well (up to 76Mbps).

Also, you say But now on NEW fibre why is there a very similar situation, we should be getting 40 instead get varying speeds up to a max of 37-38 depending on the wind direction.? I assume you are on FTTC, Fibre to the Cabinet. The fibre to the cabinet is new, but there are still the same old copper (or aluminium) wires from the cabinet to your house, and these limit your speed. You should have been given estimates when you signed up with Plusnet fibre; you can see these at http://www.dslchecker.bt.com/adsl/adslchecker.welcome and enter your telephone number. The speeds they quote are the line speeds not allowing for the protocol overhead that elfish mentioned. The estimates allow for your line distance from the cabinet, but cannot take into account all the variables inherent in these old wires; that is why they quote quite a wide range.
The old overcrowding issue still applies as well. You have bought a contended service, where you are sharing resources with others. For guaranteed speeds you would need an uncontended one, which is MUCH more expensive.
It may well be that PlusNet advertising did not make these issues as clear to you as they should have done. The 'up to' is certainly in much smaller print then the 38Mb (which should really be Mbps anyway, but never mind ....)

But to be a bit pedantic , I was offered 40 not 37-38.. It was all done over the phone, I rang up P-net to negotiate another deal as my BB was running out , and was offered Fibre as it has just been fired up in the village, and was offered 40 or 76 ?.
that's it .. no mentioning of anything else, hence my "why is 40 not 40" .
And yes the last few yards of connection ( I can see the Fiber box just up the road ) is still our old 40 year old copper..
But I was offered 76? then but some of the reasoning on here , I will still only get 38 ?, if 76 is possible ,I must still ask then why isn't 40 @ 40?

The guy on the phone was inconsistent (incorrect) giving a choice of 76 or 40, he should have either said 80/40 or 76/38. He should also have said that it was an 'up to' speed, especially the 78. Maybe he should also have explained the 40/38 difference, though I suspect most people would find having that discussed on the phone to be a little too detailed.
By the way, If you have a separate Opereach HG612 you can unlock it and see your actual sync speed. That will give an idea of what speeds you would get for paying the extra for the 76 package. I went for the lower package even though I would get around 70 on the 80 package. One feature of PlusNet is that they offer up to 20Mbps (18.7Mbps in real data) on upload even on the lower level package; most (all) other ISPs only offer 10Mbps upload on the 40Mbps download package.

http://packetpushers.net/tcp-over-ip-bandwidth-overhead/
TCP/IP overhead as a %ge varies but if I remember correctly it will never be less than 3%, and will be higher for smaller packets and IPv6.
So you'll never get more than 97% of your sync speed as actual throughput and that's ignoring losses resulting from transmission delays and retries.

It's a little more involved but still do-able if you're (fairly) comfortable using a soldering iron and a serial console.
