@j0hn,
thanks for your analysis. Yeah ADSL is not an option for me because I live 6km from my exchange, 3km to my Fibre cabinet. I cut out more than half of the metal wire by using Fibre.
I agree, I said to William before that 2Mb is junk, 8Mb is acceptable, 10Mb is fantastic for 2.8km from the cabinet.
I believe the problem is the rain getting into a joint, since the rain cleared today I haven't experienced any cut outs
