Plagued with disconnections, any advice pse. ? [Long]

Hello,

My ADSL modem / router is located in the computer room at the opposite
end of the house to the BT master socket. So to get the phone signal
to the router I used a set of old telephone extension wiring put in
about 25 years ago with alarm wire. It was poorly done, there are
spurs split off it on the way, that sort of thing, however the first
ADSL modem I got synced up immediately (to Nildram) so I didn't reckon
it was too bad.

The room gets very hot in summer and last summer I started getting
frequent line drops / re-connects every few minutes just as if the
modem was overheating. So I tried a new modem and it was no better.
Then I tried another new modem & same symptoms. The last modem I tried
(still with that one) was an A60HF wired / wireless / powerline modem
from Maplins. I'm using the powerline connection for the 2 other PC's
and the powerline connection aspect works very well, (although I
understand it puts a lot of RF noise out on the mains).

However, it's winter now and the room is Ca 20C and I'm still getting
the disconnects 5-8 times / hour. I've just discovered another
downside in that every re-connect results in the router being assigned
a different IP address and one on - line service I'm subscribed to is
accusing me of sharing my password out because of all the different IP
addresses.

Here are the downstream stats from the modem

Virtual circuit PVCO

Connection Type PPPoA

Line state Showtime

Modulation G.DMT

Annex mode Annex_A

SNR Margin 7.5

Line attenuation 46.5

Data Rate 5568

Are these any good, or bad ?

The provider is TalkTalk.

The possibility exists of moving the modem very close to the BT master
socket and using the powerline networking to connect to all the PC's
thus eliminating as far as ADSL is concerned all the dodgy alarm
cabling.

What do you think ? Sorry for very long post.

TNX. for any help.

Derek

Your first part doesn't make sense, since the second & third sentences
are the same. I think you mean the best solution is to install the
modem/router near the master socket and use a replacement faceplate
filter,such as http://www.adslnation.com/products/xte2005.php, to
isolate all the house wiring from the ADSL signal. With this, there is
no need for additional plug-un filters at each phone socket, or the need
to mess around with Iplates of removing ring wires.

I agree with the rest of what you say :-)

Wireless connections often won't work well, due to house wall
constuctions and typically offer lower LAN bandwidth, especially where
there is more than one computer.

Have you tried disconnecting the Bell Wire?

Agreed, Peter. I haven't supplied an Iplate, since I prefer to
disconnect the ring wire at the master since the ring signal will be
generated at the plug-in filters.

As you say, even disconnecting the ring wire, fitting a faceplate filter
or even an Iplate is of little point if the home wiring is done in non-
twisted-pair, e.g. alarm, wire. The basic filter design assumes a
balanced input and output. If there is normal-mode noise present on the
home wiring, then the filter won't isolate the DSL carrying part from
seeing this, also as normal-mode, just as if you'd never bothered
removing the ring wire.

for information of others, the ADSL filter works in both directions -
and does nothing on the ADSL side. It removes the ADSL signal from the
phone wiring and also removes any HF noise picked up or generated by the
phones from getting back and interfering with the ADSL signal going to
the modem.

Interesting your comment about N. I would have expected 5GHz to be
worse that 2.5 anyway in an average, non-cardboard house with people
moving about so I'll give them a miss :-) I've recently upgraded here
to Gigabit Ethernet, using the already installed Cat5e network and it
flies...
