Are you sure there is no noise on the quiet line test? If it's silent, then I can only think it's something electrical either in your home or externally. Can you try the test socket behind the master socket and see if it improves?

Do you have a neighbour from whom you might borrow a known working home hub ?

Why would that make a difference?

Unfortunately not nearest thing i have is a plusnet hub one but they are locked to plusnet usernames!

I will give the test socket a go later or tomorrow and report back thanks for the help/suggestions so far William appreciated.

In reply to a post by jdigz7:

Now i understand i am in the supposed 10 day period,

"Supposed" being the operative word. There is not, nor has there ever been, a 10-day training period on FTTC.

The gentleman i spoke to yesterday felt the need to ram this 10 day period down my throat non stop and even though i explained i was under the impression this didnt apply to FTTC he was very argumentative and guaranteed it was.

Fantastic customer service. Problem with your service? Call back after ten days please.

Is what he should have said

To prove that the fault the OP is seeing isn't due to a duff 'Smart Hub'.

I'm afraid I don't know if that router is a combined VDSL modem as well.

If it is, at least you could prove stable sync with it ?

Not a problem. Glad to help.
