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

@brunomarcs ;) Make mine a double!

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.

I would feed the ethernet cable through the walls and put a jack on the wall. Makes life so much easier.

Seems your modem is part router, otherwise not sure you’d have Wi-Fi.

Once you have an ethernet Jack on the wall, you’ll have a better connection to feed a network switch that can provide digital Signal more conveniently to a lot of different destinations

Don't complicate your life with all this extender stuff. It's not rocket science.

FYI, I also use. Node 2 using wifi. I use a RME dac with it and I had a lot of dropouts and constantly had to reboot the Node and my phone. I moved  the Dac and the Node apart from each other and my dropouts stopped. There is now an 8 inch separation where before they were butting up next to each other. A simple solution 

I mentioned at the beginning of this thread that you can buy a router that accepts a SIM card which means you don't need hard wired internet and still get 5G.

So MESH etc. is not required.
