Connecting ADSL router/modem to extension, not master socket

In the Zen Internet knowledge base they state that one should always
connect the ADSL gateway to the master socket if at all possible so as
to minimise signal degradation through longer cabling. But my master
socket is in the hall and inconvenient for the computer which is
upstairs. So I intend to connect the Thomson gateway to an extension
socket (every major room has a phone socket - it's a new house).

What level of degradation might I expect?

How long is a piece of string. I have to connect through a twenty foot
extension lead and the service is fine. I suggest you try it and see.

Anything from zero to a lot - depends on your local circumstances.

Zen's advice is sound, but chances are it will work fine from an
extension if your wiring is in good order. You can shift the odds in
your favour by disconnecting the bell wire, and letting the
microfilters take care of the ringing. This will improve your SNR -

How long is a piece of string ?

I suggest you try the router connected in both places and look at the connection
statistics.

Removing the bell wire can improve your SNR even when you're using the master
socket too.

If your extensions are not isolated, it wont make much difference, as it is
unlikely to work from your master socket, as it would from the extensions.
Signal degradation is certainly a problem on flat cheaper cables.

The advice to use the mastersocket is more for their convenience, as
troubleshooting, by isolating the extensions (unscrewing the bottom half of
the faceplate and putting the adsl cable into the socket behind, is much
easier.

To be honest, the bulk of problems people have with adsl are within the
house, rather then the bt managed part of the line.

The issue tends to be, when the line is marginal (or, on a max service, and
wanting to optomise speed).

You can use an NTE5 (?) faceplate, and run CAT5 cable from there to a
RJ11 socket where you need to plug the router in, or plug the router in
at the socket, and CAT5 to the PC.

The former is what i use as the BT Master socket is not anywhere I can
conveniently put my router, thus I ran CAT5 directly from the socket to
the place where the router is, terminating the CAT5 in a RJ11 adaptor
socket. I then just plug the router in to the socket using the supplied
lead.

Works a treat, and no lo-grade telephone extension wire in sight.

My house came with built-in wiring to sockets in various parts of the house:
each spur is probably about 50 feet long. I also got BT to install another
spur (about 15 feet) to a room that didn't have a phone socket, and that's
where my router is normally connected.

The difference in the figures between the normal socket and the test socket
in the master socket is almost unmeasurable, and at the end of one of the
50-feet spurs I only see a worsening of about 1 dB. Mind you, my figures are
good in the first place because I'm only a few hundred metres from the
exchange.

My figures (for the normal socket) are:

ADSL Link Downstream Upstream
Connection Speed 8128 kbps 448 kbps
Line Attenuation 15.5 db 4.5 db
Noise Margin 14.8 db 24.0 db


Interestingly, the stats have got worse since I was first upgraded to 8
Mbps: originally I got:

Line Attenuation: 6.5/6.0
Noise Margin: 30.3/30.0

Depends entirely on the quality of cabling, and since it's not visible
you'll simply have to suck it and see.
