- There's stable internet connection as long as no 'active' ethernet cables are connected.

- Wifi is affected either way.

- All LAN ports displays the same result.

- Occasional static in the telephone.

- Renewed all the responsible cables with tested and working cables.

- Fresh install of windows 10 have no effect.

- Updated most of the drivers before I reinstalled windows 10.

- Mobo is ASRock AB350 Pro4.

I checked the ethernet port on the mobo and seemed fine but I bought an ethernet adapter online which will arrive in a few days just in case. I live alone and the only devices I have are the PC, telephone and smartphone to troubleshoot it with. I contacted my ISP when I found out there's static in the phone and they'll be conducting some line testing from here on out. I'm not really accustomed with this networking stuff so maybe you guys could help me out.
