Slow than expected speed - advice and help appreciated
I've recently had FTTC enabled and it's slower than I would expect (and hoped).
The BT dslchecker reports the following:
High Low High Low Handback
Range A (Clean) 80 65.8 20 19 58.1
The line first synced at about 20,000 / 56,000 which is below the handback threshold. It has now improved to 19,999 / 68,621 which is admittedly above the handback threshold but is right at the bottom end of the line estimate.
The stats the router is reporting are:
Noise Margin: 15.3 / 4.9
Line attenuation: 9.2 / 9.9
Signal attenuation: 9.1 / 9.9
The attenuation in particular seems good, although it obviously the SNR that is limiting the speed.
The closest FTTC cabinet is only about 200 m away and hence if I'm connected that that one, which I may not be for all I know, I'm amazed I not synced at 20 / 80.
The house already has a Mk3 NTE fitted so that should prevent internal extensions causing problems.
Given the line is currently synced at over the handback threshold I'm guessing it will be difficult to get BT to investigate 
Is there anyway someone form PlusNet could run the tests you have available to see if that flags any problems?
From what we can see the sync speeds have improved now?
