Unfortunately my Now TV Broadband router doesn't show any error information. However, I think my theory has been blown out of the water as the noise margin has gone down to 2.2db from the 6.1db it was at earlier when I posted. I've meandered past her house (being a nosy neighbour) and the TV isn't on .

Noise has increased, if margin decreases. Of course the noise could be anywhere on the copper between you and the DSLAM. Do you have a guess route of the cable? Any industrial premises? Any schools or shops?

I do indeed have a strong idea of the route to the cabinet which is c.1060m away. Due to the geography it cannot really go any other way and historic Digital Region and BT council planning applications show the majority of the route back to the cabinet. There are no significant business premises in the area. The cable bundle(s) to the street including my address are ex. exchange only lines that have been intercepted to a new FTTC cabinet being underground all the way.

Any "radio ham" aerials around?

Or taxi businesses?

Radio hams spend a long time ensuring their equipment is ‘quiet’ Bob, likewise, taxi firms are, in my experience, rank (geddit) outsiders.

Don't think any of those people are knocking about - at least no obvious massive aerials. .

Noise Margin has returned back to 6db so I think this is a mystery we might never solve. Luckily line has been up for over 35 days now without any restarts / disconnections and hits 39,999Kbps so I suppose I should count myself lucky and stop being OCD as I'm not in the same poor situation as these guys in Wales .

I had read this as the faulty telly in the article was causing loss of sync to those nearby. Prompting my comment of why it took so long to find ... it being a fairly black and white case.

It must have been a really old TV then

I’d suggest taking a ‘screenshot’ of all the router stats when it isn’t happening to start with ... to have baseline as such. Then have the suspect switched on at an agreed time and then watch the stats.

Is an overall wider picture of the event not possible by examining the DSLAM logs ?

I'd be looking at the shielding of...well everything really. Shielding and proper grounding / termination of anything electrical or comms related might not deal with the interference, but it might minimise it.

Does the Now Broadband router have this ability? It seems very limited in terms of it's logs for example here is alll I can see.
