Best ADSL router for long line?

I have been having all sorts of problems with random loss of ADSL synch.
After loads of experiments I still haven't pinned down the problem - but
the router *does* seem to make a difference.

My Netgear DG814 gives random drops.
My friend's DG814 does, too.

A borrowed Netgear DG834 seems much better.
A borrowed D-Link DSL-504 also seems better
(though a nightmare to set up!).

If I get a new router, which is best for long lines?
I'm about 5km from the exchange and the DG834 reports
line loss about 53 and snr between 1 at worst and 24 at best.
Current snr is 10 - and it is raining!

Have you got a quality filter?
I was using an ebuyer 99p one, and had a similar experience - from 16 to
0, varying radomly.

Replacing with a faceplate filter from http://www.solwise.co.uk/ resulted in
SNR of 14.5-15.5.

Probably not - it's the one that came with my frog, three years ago.
I could change it for one that came with a router.
Or is it worth buying a special one?
Do you know of any amazingly good ones?

Means wiring, which I'm not familiar with, but will keep this in mind.
Thanks.

Draytek Vigor range has good reputation and solid performance, they even
have special firmware for long phone lines. It's office quality kit, so not
cheap.
You can find them on Ebay at reasonable prices.
The 2600VG has 2 VoIP ports, save you money in free / cheap calls in the
long run.

Actually not.
Undo two screws.
Remove old faceplate, pull off.
Push new faceplate on, and screw on.
Took under a minute.
Then you just plug in the ADSL modem into the "ADSL" socket.

You seem to have a problem with that widely varying noise margin, although
the line loss looks not too bad. Have your experiments included plugging
directly into the main incoming BT socket, disconnecting other devices from
the line, turning off dimmer switches - in fact anything to eliminate bad
connections, internal extension wiring, local mains or radio interference
pickup etc? It also makes a difference if you keep the mains power unit
well away from the router and its input wire. I have a Netgear DG834
working reliably on an even longer line (~10 km), downstream line loss 63 db
and with noise margin mostly 6 - 10 db on a 288 kbps service.

It does depend how existing extensions are connected. Some use a
standard phone plug into the phone socket on the faceplate, and are
pretty much as fast as you say. Some are connected internally, still to
the faceplate but needing a bit more work.

Yes - mine are like that. In fact I think my extension wiring could be
the problem. There are two extension sockets and the wiring for them is
outside the house - and was done 25 years ago by BT with the white cable
that they now use only indoors.

How much would a self-employed technician charge for replacing that
wiring?

Also - should I go round the outside of the house - or change to going
inside?

If you do get an 'independent' make sure that they use telephone cable & not
alarm cables (non twisted & normally stranded) as to whether it has to go
outside will depend on what grade cables they use, where they are going (is
there another possible route inside) & seeing as you are going to be paying
for the job, whether you want them outside or not...
