Parents have crap ADSL. We reckon it's a combination of the wiring and the
phones, based on testing by removing bits.
The dumb question is, will an ADSL faceplate replacement help here? Having
the entire extension circuit on the other side of the filter seems
appropriate to me, and means they don't have to faff around with filters any
(if it were my house, I'd be checking the wiring/connectors out for
problems/considering replacing it - but for now that's not really an
option - so would the faceplate help if the wiring is a bit nasty?)
Any suggestions for models/vendors?
Oh - the router is physically very close to the BT master socket.
The 2nd one one this page is probably what you're after:
(if you've got a relatively new NTE5 type master socket)
But eliminate all the internal wiring by getting a decent DECT base
station, putting it into the master socket (after filter) and upgrading
all the internal phones to use DECT. I've done this in one house with
Hmmm, just food for thought - BT once required that the "main" phone was
a conventional corded phone, presumably because of the "uncertainty" or
unreliability of cordless.
Is this still the case? (that requirement to have a corded phone) or has
that passed with time?
DECT wireless phones are useless in a power cut as the base stations
require mains power. It used to be recommended that a wired phone is
kept for emergencies. It was not a BT requirement and probably not now
so important if you have a mobile phone as well.
station(s). An awful lot of people round here found that out the hard way
in the last major power cut...
Curiously all four networks behaved differently, one went the instant the
power went, another a few minutes latter, a couple lasted a few hours. On
power restore a couple came back straight away, another within an hour or
so, the last took the best part 24hrs to return. There was no correlation
between the order of dieing and order of returning.

If you have a master socket with a removable face-plate you will find a
test socket behind it. Removing the face-plate will disconnect the
extension phones and you can plug your router directly into the test
socket. See if you get better results on your ASDL (assuming you have a
router that can report the line statistics).
The 3 suppliers often recommended for filtered face-plates are:

Plug the router directly into the test socket behind the faceplate,
and see if it magically becomes useful again - if it does, there's
definitely a problem on the internal wiring.
I discovered I had two master sockets set up in ours (one was
essentially bypassed, it was just sat on the circuit as an extension),
but it was enough to pull my connection speed down from 6Mbit to
Exactly what we did - hence 'testing by removing bits'. We then went a bit
further, by trying the extension lines without any phones plugged in, hence
the comment about it being a combination of the wiring and the phones.
Would an ADSL faceplace help in that instance?
(remembering we're not necessarily in a position where such things can be
identified - I can remote control their computer, but not their eyes :-) )
If the two master sockets are in wired correctly as a master
and a slave, then yes - but it's possible two faceplate
filters may be needed if they are simply wired in parallel on
the incoming BT wires.
I've seen this where a system, having two phone lines was
"converted" back to a single line. The customer probably
wanted both sockets live so someone simply connected the two
masters onto the one incoming line rather than correctly wire
one as a slave off the one master or replace one with a slave
socket. If you have this arrangement, then both masters are a
combined "point of demarcation" so you need two faceplate
filters - or pay for the regularisation of the circuit.
You can't mistake a modern master with its divided faceplate
and the visible screws that only remove the lower half. With
these, simply replace the lower faceplate with a filtered
version from e.g. ADSLnation, and reinstall the house wiring
onto the correct terminals on the back of the filter or use
the front telephone socket.
If it's an old installation, then the master and slave sockets
could be externally identical with both having the old BT or
even a GPO logo. You can only determine which is the master
by examining the internals for the extra ring circuit
components which includes a largish capacitor. If you have
these, then you cannot fit a faceplate filter unless the
master is also converted to the new type - which you aren't
supposed to do, unless...

You first need to identify the wiring layout. Is there one master
socket from which all extension wiring comes? If there is, are the
wires from the extensions connected to the correct place in the
master socket? Or is the cable split outside the house and there are
two what look like master sockets?
If there is one master socket wired up properly then replace the
bottom bit of the faceplate with something like

from the back. This should improve ADSL, though nothing is

That was indeed my idea. One of the "removing bits" stages was removing the
faceplate and using the direct connection underneath, which is how I came to
the conclusion that the wiring was squiffy on the extension side (which
appears to be correctly wired to the faceplate - it's a relatively recent
install by BT).
Thanks to all for answers - it seems like I'm on the right track.
