There is a ton of things left out such as from the start buy a good modem router combo like the motorola 8702, then buy a decent Linear power supply to clean up the noise ,little green computer 12 v 8 amp.
then you needto buy 2 quality Ethernet cables ,and from Sonore a deluxe
Ethernet to fiber optic converter for noise can’t travel overnight , then at your Ethernet end point the Sonore converter from fiber optic back to ethernet
Jcat makes excellent usb and Ethernet cables , to do it right and at your Sonore end point the Linear Tube Audio has by far the best LPS power supply and for $750 with very good DC cable is a bargain. Put in a synergistic Purple fuse
parts connecxion has 20% off sales thisis if you want to truly eliminate the noise
for digital noise travels house to house ,Yes even if in packets that’s why I recommended a Quality combo that has docsis 3.1 which is 4x faster and far better processing power the the LPS to clean up noise to start the digital signal down stream then a hub converter . Jus5 go to little green computer , for example
