Yes absolutely I was getting noise in my system a few years ago realized it was my modem/router. I moved it one shelf higher on my rack problem solved.
Tube interference from router
Anyone experience interference problems from a router?
I hear noise from a tube on one of my amps and when I turn off the router it goes away. Aside from replacing the tube, the router may be interfering with other things and wondered if anyone has any way to shield a router. Must be the Wi-Fi signal because I can leave the modem on no problem.
