When I first set up my mesh network I set up the node in my stereo cabinet. BIG mistake! While my Node2i was seemingly unaffected, my phono front end was unusable.
The solution was simple. I moved the mesh node across the room and ran a 25’ stretch of Cat8. Voila! Blissful silence. If you think about it, any wifi appliance IS going to be an RF generator, right? ;-)
Happy listening.
