Many thanks to Bob Pullen for sorting my connection.
The slight problem I have now is low download noise margin - right now it's 1.6
Yesterday evening I lost connection 3 times and I'm pretty sure it's because of this, overnight it didn't drop at all.
A reset syncs at 3.0 but it naturally drops if things get busy.
I just wondered if DLM would pick this up and adjust my sync margin. I would rather lose a little speed in favour of a more stable connection.
