I read that you can find the source of electrical interference by using a radio so the geeky side of me though I would give it a try as I dont think I really have any interference anyway, the kids thought this was great.
The noisiest thing seemed to be the hg612 3b white psu itself. The noise kind of sounded like some sort of loud engine, tractor or digger type noise every time I put the radio near it. Other power points, tv etc only a slight hum. Is this normal, can anyone else confirm?
My speeds are fine but I do have interleaving on my upstream which I believe is unusual for a 400 m ish line and I am wondering if it is this.
