surge protector/arrester & ethernet switch

[Guest guest]

Is there a difference between surge protector, surge suppressor, and surge

arrester? I'm confused by the terminologies.

I tried Belkin surge protector + remote switch. However, AM radio picks up a

lot from the surge protector itself. When my laptop is plugged into surge

protector, the USB keyboard will also have frequencies on the AM radio. If my

laptop runs on battery, the frequencies on my keyboard diminish.

I also looked at a one-socket surge protector with 43dB rating, and it also had

harmonics?

What is Furman? How is it different than other surge protectors?

Anyone tried different ethernet switches? Some can also add pulsing frequencies

on ethernet cables as well as power lines. Put your AM radio on the cable

directly to best pick up whether the frequency is from the wire. Change the

channels, as only certain ones are strongest.

(Changing ethernet switch seemed the best solution. However, I wonder if there

are any other solutions, e.g., Will ferrite bead on the wire help at all, or not

really?)
