What you describe combined with the length of run points towards interference. Or maybe badly terminated ends.

If you read one of my posts above this should be largely irrelevant for ethernet. That's the whole reason why differential signalling over twisted pairs is used, any interference is applied to both pairs and therefore when you subtract the two signals the noise is simply removed.Hopefully not directly alongside each other?
Well after installing many hundreds of thousands (I used to own a cabling company from the days of ArcNet until 2011) that is definitely not the case. The theory is as you say but the reality is somewhat different.If you read one of my posts above this should be largely irrelevant for ethernet.

Yes I appreciate its an oversimplification but by and large running ethernet parallel to mains shouldn't be an issue. Ideally you'd do that or perpendicular.
It's beside a SWA cable. It's working right now so I'm happy. When it fails again I'll move stuff around, assuming I've time. And probably pop a little switch in the run as close to the start as possible.

What should be OK in theory is not always OK, especially where mains cables are in the equation.
Even when a pentascanner says it’s OK that’s not necessarily true. Connectivity and reflected length can be fine but a cable still doesn’t work reliably, and it’s nearly always interference.
Also much more prevalent on gig than 100meg.
It’s also one of the many technical reasons why mains power line Ethernet extenders are a very bad idea, not least because of the sheer amount of interference they generate. Ask any radio ham.
Just because you can doesn’t mean you should.I have them all over my house, including to my temporary shack and I really don't see the problems others talk about
Going back to first principles, if there is not a route for the interference into the radio then surely its irrelevant?
My antennas are well away from any mains cables and my radios are all properly connected with ferrites on cables
Just because you can doesn’t mean you should.
So YOU are fine, great!
How about everyone else in your vicinity? Including those unfortunate enough to share the same electrical phase, like every 3rd house up your street.
You carry on like Admiral Nelson, “seeing no ships” but whether or not you choose to acknowledge the facts, electrical interference is very real.
Ferrite cores won’t stop interference entering via the power cable, they are there as a token gesture mostly under EU law where “equipment must not cause interference and it must accept interference caused by others without affecting operation”
Like I said, Admiral Nelson.What are you talking about?
You have contradicted yourself several times, either the interference is an issue or it isn't, your last post says both
