Another thought, as you're fed from a pole:

Are your overhead cable and drop cable both twisted-pair,
with a block terminal at the join of the two ?  I.e. as
per a modern installation.

I'm convinced that a non-twisted-pair drop cable will make
ADSL more vulnerable to RF interference from LW/MW transmitters.

I live fairly close to both Brookmans Park (BBC MW transmitters)
and Saffron Green (IBA MW transmitters).  My ADSL sync speed always
drops when it starts to get dark outside, and that sounds like the
effects of more RF interference at night.  I'm trying to work
out how to avoid paying BT to sort out my feed.  The overhead from
the pole isn't (as far as I can tell) twisted-pair, the drop cable
certainly isn't (it's figure of eight, like bell-wire), it'll have
the nasty 'twist the wires together' join under the eaves.  Then
there's the 1930s bakelite lightning protection box with two fuses
in, before we finally reach a non-NTE5 master socket.  One of those
installations that makes me surprised that ADSL works as well as
it does.
