are there any extension wires or is it a "master-only" situation ?

Full factory reset, powered off for 30 mins with nothing else on the line, stats seem the same afterwards:

I haven't unscrewed the face place, but it's plugged directly into the main socket and I've tried a couple of different telephone cables, doesn't seem to make a difference.

You have a little more speed on the upstream but still that rather odd 0.5dB attenuation.

The downstream is looking reasonable.


Can you get a copy of Router Stats Lite and get that to plot the sync and SNR figures over a 24 hour period and then see how the margins vary.

if there are extension wires they can make a difference, give it a try in the test socket just in case.

OK, I think I have got router stats lite set up correctly and running and keeping a log.

Thanks again for your help. I will update this thread once I've collected some data.

I'd be looking at trying a different router first off.

Ran router stats lite for 24h or so, noise margin never changed from 6db, sync speed never changed from 19003.
