How do I switch from Wi-Fi to Ethernet cables?

Banking is undoubtedly an important actvivity, but one doesn’t need ultra reliable digital information transferance to achieve it.  Correct perception of sound is a different process, where a few microseconds in timing can affect the architecture of the data read.

  Wired is better, but it’s a matter of degree, not a night and day difference if one has optimized their WiFi setup

Not everyone has a DAC that relies solely on usb.  Timing does matter.  I have had at least three streamers, at varying price points, where the Ethernet connection was audibly superior to the WiFi.  I urge the OP, if he isn’t convinced, to run a long Ethernet connection as an experiment, even if the cables are temporarily in inconvenient areas, and compare to his WiFi,.  For the purposes of this experiment the cheapest CAT-5 will do.  If he doesn’t perceive a difference, then just optimize the WiFi.  If he prefers wired, then make the one time expenditure to get his house wired.  A competent installer shouldn’t require more than an hour, and doesn’t have to be a music business specialist.
