slow here in the country I guess.


Some of the speed benefit will be down to the lack of picures on the
index pages.  Text loads a lot faster than pictures.  I have tidied up
the html page code a bit, and added a Table of Contents for quick
reference - there is a link at the bottom of each page to get back to it.

I don't know how it works in France, but in the UK the telco, the phone
company, is responsible for the wiring up to the master socket, the
first phone point in the house.  The in-house wiring is up to the
homeowner, and may have been installed when the house was built, added
to by previous occupants, or all be DIY.

In my case it was all DIY, done with the four-wire and six-wire BT
signal cable of the time (25 years ago)(by me :-) ).  This cable is *no
good* for broadband, and I have resorted to connecting one of those
little splitters to the master socket, so that the house wiring only
gets telephone signals and the broadband router is fed from the
splitter.  All this is pending my rewiring the house telephones with
twisted-pair cabling, which will support broadband.

If your house wiring is not to modern twisted-pair standard, it could
affect the reliability of the broadband signal.  This should be may
noticable as the broadband light on your modem flickering even when
there is no computer activity.  If you are a long way from your exchange
the signal may be pretty degraded already and any slight fault will be
critical.  Your modem may be falling back to a slower connection speed
because it can't get a reliable connection.

Digression:  dialup modems work at the same frequencies as the human
voice and can connect using almost any voice telephone wiring. Voice
frequency transmission doesn't require much in the way of special
cabling, just good connections - a piece of wet string can be made to


work.

Broadband uses higher frequencies which do require some sophisitication
in the transmission line.  Twisted pair is a transmission line that uses
pairs of wires to carry each signal.  By twisting each pair together it
becomes much better at rejecting noise and can carry higher frequencies
for further (there are lots of complicated electromagnetical reasons for
this). One of the deciding factors about whether you can get broadband
at your home is how good the cabling is between you and the exchange -
if it's old-fashioned straight wires you're usually out of luck.

Um, I do go on a bit. Hope that was some use. 


Great, I do understand that, I'm not to bad at wiring. just a little slow at
doing it owing to the thought process.
The wiring is all standard telephone cable six wire,done by me in 1998. I
hope it's not too old I will look and see if it's two strand or something
else.


For best results with broadband it should be twisted pair, two or three pairs of wires, each pair twisted together.

Our phone line comes in from the Telecom line to one point, from there I
have three extensions, one is to a UK box so that I could plug my phone/
fax/ answer phone in, typically the french telephone plugs are a different
shape and the Uk combo wouldn't work when we first got here. I also have two
extensions one in the bedroom (never used) and one in the office.

 The modem box is plugged into the main telecom socket. I don't know if it's
what you would call a spliter but it plugs into the main socket with a
telephone plug hole for the normal phone on the one side and an smaller
socket that takes a cable to the modem underneath,


That sounds like what I called a splitter, also known as a microfilter.

then there is a phone
piggy backing off of the modem that  gives me "all inclusive " phone calls
within france, for that I had to wait a few  days from plugging in the modem
but it switched on after 3 days I think.

That sounds like an IP phone since it is on the broadband side of your filter. Have you tried removing this to see if it has any effect?

I still have phones plugged into
the Uk socket and the office socket from which I can call mobiles and or
outside France as I have cheaper deals for those calls than the broadband
service can currently offer. I seem to be able to send big files very fast
so that side of the broadband bit is working but picking up emails or
loading web pages via broad band takes forever and I'm not exagerating.
Yesterdays trial took 20 mins for one note on the news group to appear!


Hmmm.

Broadband is asymmetric, that's what the A in ADSL stands for. Upstream speed is typically 256MBps, or about five times better than dialup, while downstream speed should be at least twice as fast as that on even the cheapest broadband connection (512 MBps). Ours is twice as fast again (1MBps) and should go to 2GBps soon (telephone exchange upgrade). If you are getting upload acceleration then your broadband is working .. Your modem control software may give you a page showing how fast the upstream and downstream connections are.


The modem box has a long  start up process when unplugged and replugged and
hovers around the PPP stage for several minutes, this is the main part of
the problem I believe, so at the moment I am living in hope that it will
soon be solved and I can stop geting on my knees to unplug and replug
between the dial up and the broad band, just in case it's working today!

Claire, our master socket is of a design that allows you to undo a couple of screws and then unplug the faceplate, isolating the house wiring and exposing a socket which connects to the external line only and nothing else.

If you have something similar, try removing the faceplate (you'll have no phones while you do this) and plugging the microfilter directly into the master socket. If this gets you a good broadband connection, then your house wiring is having a bad effect on the broadband signal. If possible, plug the house wiring into the other socket on the microfilter - you may need another adapter to do this, just to get the physical clearance. This is how we are at the moment!

if this doesn't work, it may be that your ADSL modem is faulty, or that the telecom supplier's equipment at the exchange is not working properly. You may need to get them to come out and test your line.
