Hello TP Link community, 

I have a noise problem with a pair of TL-PA9025P Powerline Adapters.

The microphone of my desktop computer is unusable because of it, the mic is recording almost only static/crackling noises.

When I unplug the adapter, the noise goes away.

I first thought that my computer was the problem. This computer then fried a couple of weeks ago (my PSU, a SATA cable, one HDD and one SSD all fried).

I replaced all the parts and cables (everything is brand new) but the problem is still there when the Powerline Adapters are plugged in.

I asked an electrician to come and check my electrical network, which clearly appears to be at fault, but he said that everything was fine and didnt find the source of the problem. The electrical network is only 4 years old and was set up by this same guy.

I sometimes have light bulbs switching intensity and crackling as well...

I once witnessed that my computer and my home router (communicating via the Powerline Adapters) lost sight of each other while a light bulb on another power circuit was crackling and switching intensity.

I tried another pair of Powerline adapters (TL-PA8015P) and the same problem appears, altough there seems to be a little less noise.

Does anyone here have any experience with a problem like this ?

The electrical network seems to be at fault, but I have no idea where ... 

I'm going to get a second electrician to check it out, but any help from this forum would be greatly appreciated.

Sorry for my english and thank you for your time, 

Martin
