Repeated drops / blips at random times, had engineer out twice

Hi,

I see other people occasionally having the same issue so I wondered if there as any advice. I'm having random moments where the internet will blip,  sometimes causing the router to flash but most often not. It does come up on my various hardwired devices though with messages like "LAN cable disconnected" for a second and then "LAN cable connected" again. It's been happening for a while and is really becoming a problem for my work as well as my son's hobbies.

I've had two engineers out, both of them said the signal outside my house is fine but the last chap reterminated the connection and put a new splitter on. It seemed to help for a couple of days but today I'm back not being able to take video calls again. I've disconnected some MOCA connectors I had to get the internet upstairs and am currently dangling a cat5 cable out the window, I've totally disconnected the splitter so it's a straight shot from the street into the modem, and still the same problems. The gateay was getting hot enough to cook an egg on we improved airflow to that, still no help.

The last engineer said that before his visit they could see over 1200 disconnects on my line! Not sure how many since as I'm trying asking a question here before just calling out another engineer.

These are my signal tables right now:

Any help genuinely appreciated, it's driving both me and my son nuts, and beginning to annoy my co-workers.

I've read online that this sort of thing may have something to do with something  called "ingress" and need escalating to some sort of maintenance team that is above the standard home engineer level of support. Apparently they can do different tests and even look at junction boxes in the neighbourhood.

If that's what is needed how do I ask for this, or get Xfinity to confirm it's required on their end?

Again I'm grateful for any advice.

I'm actually looking at switching to Fidium that are new to my area. Perhaps a fibre connection won't suffer from whatever is causing these issues.
