For some reason Sky told Openreach there was a fault on my line. Just had openreach here.
Told him about the drop outs and he did a few tests. Had to pop to my cabinet and reset the circuit as his equipment would not connect through my socket. After the reset it connected fine.
He said my line is 650m. Thats from my socket to the cab and its 4.1km to the exchange.
Anyway this is my stats now
Broadband Link Downstream Upstream
Connection Speed 35469 kbps 7295 kbps
Line Attenuation 26.4 dB 0.0 dB
Noise Margin 6.1 dB 6.6 dB
It may change but lets see how it goes I suppose.
