I plan to buy it, and also use those ethernet ports


It only works for a few days tops. Many, many have tried it and this is the experience for all of us with this issue. If you want to see for yourself just purchase it test it for a week and return it (make sure its returnable).
If a solution works only for a few days then it's a placebo. If any solution works only for a few days then maybe the problem you are trying to fix is imaginary as well. I experienced it myself many times. Every magical fix I tried to use in the end proved itself completely useless despite making a big difference at first.
I heard that with other power conditioners, but apparently that furman doesn't have that problem, or at least is less of a problem.
Nope its not a placebo. It is the nature of this issue. Something is saturating and it stops working. I am not an electrical engineer so I cannot explain this phenomenon however I am 100% beyond certain it is not a placebo effect. Many, many people with this problem report the exact same experience. Inputs work excellently and consistently for the first few days/week and then it degrades back to normal.JDoe wrote: ↑25 Feb 2021, 02:00

I can assure you that happens with the Furman. I have tested 1000$ Furman's, the M-8X one you speak about, and many others from different companies. The phenomenon is always the same. The higher grade ones work slightly better overall. I can give you a list of all the conditioners and power filtering I have tried if you would like. Its not magic sure but, the symptoms are absolutely some of the strangest most illogical stuff you will ever observe. That is why I think its RFI. Even experts describe its effects on things as "black magic" because it can be so inexplicable.deama wrote: ↑25 Feb 2021, 09:33

Still though, this stuff isn't magic, if you have a serious electrical problem, power conditioners aren't gonna fix it I think, maybe if it was a super one like they use in server farms or something.
I wonder, if people live in a sunny place, could try to make a solar-panel + battery combo, might work; expensive though.
