I was trying to keep it simple. The faceplate was modified before
purchase (purchased on the internet). On the back are the original
three positions for phone cables to which I have connected three cores
of the eight core cable. There is a second connector on the back. I
have connected two cores to that (and the same to the RJ11 (RJ45?)
socket on the extension. The router does work so it must all be
connected properly.



At the moment it is wireless as I can't get the ethernet cable to
work. I did have the router at the master socket until today
(connected wirelessly), but I decided to try it on the extension to
try a wired connection. This seems to be something of a disaster so
far!


I suspect you may have a problem, or several problems.
I'd query whether the midified before purchase faceplate has
a built in ADSL filter (one or more ferrite ring core torroids and some
capacitors).
If there is a filter it should be between the incoming phone pair
and the phones (the filter SHOULD NOT filter the 2-wires for
the ADSL, these go straight to the incoming phone pair.)
That is the modem part of the router is connected one-to-one
to the incoming phone pair.
The filter toroid + capacitors goes to the phone and most
modern phones don't need the bell wire, a few are fussy
which way round the phone pair is connected polarity wise.
Commonly IF there is a bell wire there is a bell wire
capacitor.
Ethernet is a bit tricky to wire, it is not 1 to 1, Google
for ethernet wiring, in some cases the PC to router needs
crossover wiring. Mine did, the faceplates were
marked and color coded for the A and B ends. It then
all worked with standard flexible patch cables at each
end.
Straight untwisted is not good for the ADSL pair, it could
reduce your sync speed, which is why twisted is recommened.
Router next to NTE5 is best.


The faceplate is fine as the router (off an extension) and phones work
fine. The faceplate is I believe built to BT specifications.

The router works fine wirelessly. The problem is with the ethernet
cable. I thought it might be a faulty cable so I borrowed another
one, which Windows 7 still says is unplugged. I know about crossover
cables but as far as I can see these are not common for routers. I
may phone the manufacturer's helpline.

Once I can get the router working I hope to compare speed between
master and extension socket.

Look at the time stamps. The OP did not orignally state that & my
post was in responce to that not what he later posted.


You didn't get the OPs OP then?
6/6 1506


As OP I see I referred to a 'splitter frontplate' without spelling out
that it contained a filter. Maybe I could have been clearer, but for
the avoidance of doubt this is a frontplate with built in broadband
filter.

I suspect I am going to regret asking this question.

I have read the varous comments about the importance of using 'twisted
pai' cable. I have the following set-up. I fitted a splitter
frontplate to the master socket. I then ran an 8 core cable to an
extension in my study/bedroom which has a split telephone/computer
outlet. Two of the cores are for broadband and three for telephone. I
tried disconnecting the earth wire but the phone stopped ringing. I
then plugged the router into that extension socket. Am I making a
mistake?


YES.

Read some stuff up online. Amateurs shouldn't even attempt this stuff.

Is that it then, you're not going to qualify it?

What the OP is doing seems quite reasonable and standard for a central
faceplate filter where the router needs to be sited remotely.
The only provisos I would give a

1) I would have used CAT5 for the common cable, but he might
have been stuck with what pre-existed.
2) I definitely wouldn't run the bell wire in the common cable.

I've tried CAT5 and found no improvement over common 4 core 'phone' cable (
sorry can't remember the CW number ).


2) I definitely wouldn't run the bell wire in the common cable.


The bell wire is rarely even needed with modern phones. And it certainly DOES
cause balance problems when run from a master socket onwards.

Well your corrupting your DSL signal by placing a non filtered phone
in line, but if it works.....

But he's not.
He's using a NTE5 faceplate and running filtered and non filtered pairs
to a remote BT/RJ11 plate using a single cable.


There are quite a few versions of NTE5s now thanks to BT's daft idea of not
giving each one an individual designation. Some ( the new ones - ALL new
ones ? ) have a filter inductor on the bell wire to improve ADSL
performance. Look on ebay for those stating they have the bell circuit
filter.

How about a link to the one you have ?

Sorry to be a pedantic pain in the butt but:

Your sig-sep is broken.

Whatever adjustment it is isn't obvious, and if I wanted to send an
email (say you had made some goof I was trying to warn you about) why do
you make it hard for me to do so?

notcoldmail.com has not been registered yet, therefore you do not own

I suggest you read the advice here carefully:

Graham if the faceplate contains the DSL filter, by default the bell
wire will be filtered...

Whose ( which brand ) faceplate though ? I'm not sure that's universally
true. Just another of those nastly little things to catch the non-expert
( i.e. public ).
