Hi all,
i just installed 2 TL-PA8030P powerline adapters and they seems to work.
But as soon as I power on these devices I can hear clearly a noise coming from the audio speakers of my PC plugged to another wall plug. This sound remember me the noise of the old 54k modem while connecting to internet (less louder, I admit).
Once I shut off the powerline adapters the noise disappears.
How can I solve this?
Thanks in advance for any suggestion.

Tony

What you hear is the powerline signal, which, obviously, is on the power lines. Your speakers apparently do not apply reasonable filtering in their electrical design.

Two ways out: (A) use better speakers or (B) use a mains noise filter. The 8030P contains one such filter, so if you plug the speakers into the 8030P's through socket, things should improve.
