[re: MrSaffron] [link to this post]
 
Fair point MrSaffron! Nothing has changed with setup or in the house. Maybe a neighbour has gone away for a few weeks!

BT Infinity 2 - Predicted speed 54.7Mbps down/15.7Mbps up. Actual speed 42Mbps down/4.5Mbps up...crazy Left BT as they were poor...
Now with Sky Fibre - 37.5Mbps down, 9.5Mbps up
Router stats - Connection speed 40000 kbps down, 9997 kbps up - Line Attenuation 19.1 dB down, 0.0 dB up - Noise Margin 13.1 dB down, 10.10 dB up.

But you're lucky in that you have a very short line and your attainable speed is in excess of what the line will support.


Care to explain how an attainable can be higher that what a line will support?

The max attainable is the maximum that a line will support.

Except that in these days of 6/5/4/3dB FTTC noise margin settings it isn't. Quite apart from it fluctuating continually.

I think the poster you replied to simply worded his post badly, if you look at what he was replying to.

Thanks RobertoS - I did indeed word my response badly. MHC - what I meant to say is that max360 is on an 80/20 plan, but the line is capable of more throughout as evidenced by the max attainable rate of the line, not that speed above 80/20 would be achieved as the product doesn't permit that.

giggsy1977 You may get a more accurate result by using the address checker.
If not, the number of a nearby neighbour on a bt / reseller line certainly will.

Thanks gymno74 - it was the address checker I used as I don't know anyone on BT unfortunately to check. I have noticed over the years that my estimated speed has gone up (a little) and I have used a neighbours address and there's is a little lower than mine. Guess it depends how the cable is routed.

Ah ok.
I thought maybe you'd used the specific postcode checker & missed the address one.

I should have known better than that. smile

The pure Postcode checker no longer gives FTTC/VDSL/FTTP data. It doesn't even show the lines.

If you enter just the postcode into the Address checker you get a list of all the addresses in that postcode, and can include several different cabinets. You can check the estimates for all products for each address. (Database errors excepted).

That is what giggsy was using smile.
