To Randy's point, I keep my computer audio front end and router/modem electrically isolated from and around 10+ feet away from my analog gear using 20' long XLR IC's from DAC to preamp.
I got better sound using wireless than from a long Ethernet cable. Can't really buy that with all of the RF from phones/wireless devices shooting through the air that the location of the router/modem (to avoid RF noise) is that critical. As stated before, it is more likely the noisy power supplies in consumer computer-related gear that creates the sonic issues and that can be managed. YMMV.
