Also when inserting the fibre through a narrow hole in the wall, the fibre cable was bundled tightly with several other cables already snaking their way through the narrow channel. So electromagnetic interference is also a possible culprit.

Electromagnetic interference does not effect light. That's 1 of the benefits of fibre.

Surely arranging for an Openreach engineer to visit is always the last resort with ISPs? That’s been an experience anyway: First it’s resetting equipment and changing software configurations, then replacing it, and thirdly addressing physical issues with the connection itself by sending out a technician to test the connection at the source.

Okay - good to know. Thanks!

All you've done there is give Zen an excuse to book an Openreach appointment and wait until that's happened before addressing anything else.

How else would you advise me to proceed with attempting to rectify my technical problems?

Its my experience that ISP typically raise a ticket with Openreach before considering an issue to be caused by themselves, so by you sending that email you have played into their hands.

Okay - that’s a really useful perspective. Will definitely incorporate that in how I proceed.
It’s sort of coming full circle as it was an Openreach engineer who originally pointed at Zen when he correctly advised me to pressure them to cease and reprovide.

From your earlier statement “ Massive packet loss showing and Zen support corroborating this.
Strange - no real world symptoms apart from erratic Wi-Fi speeds….

Edit: the strange thing is it doesn’t seem to be affecting real world performance.”

It is very likely that you don’t have packet loss. If you did have the amount of packet loss that graph is showing you, your connection would be unusable. Something weird is happening that is causing that behaviour, but if your main gripe at the moment is shonky Wi-Fi performance, then you are barking up the wrong tree.

You can prove this yourself. Plug a computer direct to your router, and continuously ping something for a while. See how many are lost. The graph would suggest 25-30%. From memory on windows you can do ping -t 8.8.8.8 for a continuous ping. I bet you actually see closer to 0.

As for what is causing that… could be your IP has been recycled and someone else had similar monitoring set up that they’ve left on? Could be your router is a little broken in some special way? It’s interesting, but unlikely to cause you any actual issues with your service.

Which is why I mentioned close to the ONT and/or router. Meaning your side of the ONT .`

Thanks for your thoughtful response, SteveBen. Will definitely do a ping while my computer is connected to my router via Ethernet next time I’m at the property (Saturday hopefully). The only clue I have is a very serious pattern when I last used a Fritzbox (as I mentioned in one of my earlier posts in the thread) - however at the time that cleared up when I made sure there was only ping monitor active at a time. This time it appears to manifest even when there is only one monitor.

I get the distinction now - thanks.
