What are the differences between a quality filter or perhaps a
cheap one.

Almost none of value. Not least because the ADSL signal goes
straight hrough the filter. The filter's job is primarily to stop
nasy noises on the phone. Peter Crosland will however bamboozle
you with all manner of old wives' tales about them.

I had a weak connection like the one you've posted about and
swapping filters ( I had 3 types) helped not one jot !

Removing the bell wire (number 3 in the socket) to any extension
sockets may help though. It creates imbalance in the ADSL signal.
In fact in your case I'd be confident it would help but it's a
bodge not a cure.

Wrong again G, the bell wire itself is an unbalanced wire,

It's a single wire so it can't be balanced. That much is true.


it doesn't cause an inbalance of the DSL signal.

Yes it does.


What it can do is pick up any ambient RF noise & feed it back into
the master socket to one leg of the balanced pair reducing the
bandwidth width available

Even if it did pick up RFI as you say, there's no way that reduces
*bandwidth* ! In fact with the bell wire involved, you'll get a
poorer connection, RFI interference or not. It's inevitable, merely
the degree of degradation is at issue.


but it doesn't cause the balanced pair to become unbalalnced..

You've got it wrong.

It destroys the balance of the line, not least because the ADSL
signal is no longer just passing over a twisted pair. Line balance
is critical to the operation of ADSL ( and POTS too as it happens
btw).


Love to know where you bought your qualifications from, they must have
been cheap or else you wouldn't have got them.....

You keep getting things basically correct & then run off at the
keyboard at a complete tangent to what the real facts are...
