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

If you end up running any wire, I would suggest cat out to a fibre media converter, make the long run to where your dac sits with optical fiber, then use another media converter for optical back to ethernet with a very short, shielded cat 6/7/8 cable.

Should not only “clean up” any analog interference from the router side, but also, as optical isn’t affected over that run from electromagnetic interference, you’d end up with a pretty dang clean signal to the dac.

Seems like the ethernet over powerline adapters (~$40) to an optical segment and back just before the streamer would proved the most flexibility.  The optical portion, with a nice short shielded ethernet cable to the streamer, can be had for under $100.(newegg)

My node2i always had signal issue with wifi, 2.4 or 5, with no walls between wifi router and it. It isn’t the wifi spec, it is the interference and the specific streamer device’s capabilities, and internet service, that are the issues I have had with audio wifi.  Innuos pulse mini now, no wifi on it.. with an optical section… much happier now.
