This the best I could manage https://www.thinkbroadband.com/broadband/monitoring/...

That's perfect for us to see. But a dreadful graph!

It doesn't look to be the "live" one? Showing up to 11:30pm or thereabouts?

Re the timescale across the bottom it becomes a true rolling 24-hour scale after a full day, and you can then select days from the history for static posts.

Edit: Of course it can't be live as you say Zen wanted you to disable it!

Hi Jimbof,

Yes they have placed their own monitor on my connection, but only after they requested I disabled mine - and according to them there was still bad packet loss showing.

You are not having much luck.

I hope it all gets sorted soon.

In reply to a post by kam67:

Could this be a symptom of a bad splice, or is that unlikely?

Indeed it could. That's actually the most likely course of events with a new FTTP install.

However: I would expect it to be causing you some serious performance issues.

How's https://packetlosstest.com/ looking?

you using a fritzbox?

They throttle pings.

Hi Chrysalis,

Yes - a Fritzbox 7530 that Zen provides as standard. Was also coming to the same conclusion about the Fritzboxes rejecting pings - As had the same issue with the same Fritzbox model on a Zen FTTC connections couple of years ago. Tempted to try a third party router. Maybe one of the better Asus (like the Asus RT-AX86U or RT-AX88U) routers?

Thanks, Adrian - no not much luck 🙁!

Yes they requested that I disable it.

New email I’ve sent the complaints manager at Zen charged with addressing my well documented issues:

Sadly, it seems my trials with the new FTTP connection have not been ended. It seems to be a case of out of the frying pan…!

I’m increasingly suspecting that the cause of the severe packet loss that I’m experiencing lies with the serious problems I observed the Openreach technician having when he made several unsuccessful attempts to splice the fibre at the box affixed to the external wall of the property - the CSP (Customer Service Point).

The fibre kept breaking and in the end he rushed the job.

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.

So sooner or later, I have a strong hunch that Zen will need to send an Openreach engineer to repair the fibre connection.

Of course if in the meanwhile you manage to fix the problem with the packet loss by another means all well and good.

I look forward to hearing from you soon.

Kind regards,

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.
