Issues with network link to office via Powerline

[meggiedude]

Lo there.

Been struggling a while with this, and now I have the new PC setup I need to get this solved, as its compromising my spangly new setup.

Running Cat5, wireless and powerlines round the house, and the only issue I see is intermittent internet disconnects between Office PC and my router.

The office is on the powerline setup, as is one of the router ports. All powerlines in the house (4) are 500Mbps and gigabit ports.

Every now and then the internet drops out in the office on whatever PC is plugged in to the powerline.
WLAN is not affected, and neither are other CAT5 or powerline connected items around the rest of the house.

I have changed the powerlines around, put a diff router in, disconnected most of the other electrical items in the house to rule electrical interference out. Basically done most things, but I still get a disconnect betwixt PC and router several times a day.
Connection re-establishes after a few minutes, but if I want a quick fix, the only workaround is to power-cycle the office powerline unit.

Is there any utility I can run on my network to find the cause.

Cheers

Nothing that I know of. Sorry if any of this is obvious but some ideas:

Are the power line adapters directly plugged into the wall? They hate surge suppressing extension leads and you tend to get those in computer rooms.

Worst causes of interference are motors/pumps, generally anything that goes around and around. Listen out for things like washing machines, dishwashers, even central heating pumps firing up when the line drops. It might be that *they* are the things that need to be on filtered extension leads.

Have you tried directly connecting the 2 powerline adapters to 2 computers? and monitoring for network loss?

Aaaaaah, Central heating pumps!! Well maybe that is it.
I know that Surge Protectors and Powerlines don't mix well, but I'd forgotten about the Central heating.
The spare bedroom/office I use has the hot water cylinder in a cupboard not that far away from the sockets where the powerline is plugged in.
Obviously within the plumbing in that cupboard there is the central heating pump, Hot-water/CH diverter Y valve and all manner of other plumbing bits and bobs.
Maybe the central heating pump is the issue. So maybe, as a test, (when the weather gets better) I turn off the CH for a day or two and see what happens.

Nice one mate.
