I am about to get BT infinity 2, all being well, on Tuesday having been on ADSL previously. It's a self install which I gather is standard now.
Turns out I'd always been using an extension socket getting 5mb/0.5mb or so speeds. Connection always seems stable. Having discovered the master socket behind a cupboard in my son's bedroom (sigh), this went up to about 6mb.
But this master socket seems a bit of a mess. It has a loose dongle of some sort hanging out of the top, which I wonder if perhaps it is the wiring coming in and past another dead master socket (I recall the previous owners of the house had two landlines; presumably this was for the other). There is a lot of wiring concealed within and 2 wires go to port 2 and 2 to port 5 in the master (we have extension sockets in virtually every room although I have never tested them all).
I've removed what I believe to be the ring wire (orange from port 3 and 4) and this increases speed to just over 7mb. Using the test socket goes up to 7.25mb so not a huge difference.
Is there any mileage in buying a Mk3 interstitial faceplate thing - ie, might it improve things (presumably it can't hurt, or can it?) or should I just wait and see first? I'd rather not be mucking around too much post install and seeming to cause errors on the line.
We are using a downstairs extension for the landline.
NB dslchecker suggests I should be getting 4mb download on ADSL so presumably the wiring generally is not too bad, not sure what this means for VDSL though.

Thanks for any input.
