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

@balooo2 , with respect to your "daisy chain" description, not quite. To daisy chain something means that you configuring whatever to be in series with one another. However a *mesh* system is not "in series". Here's a good explanation:

https://www.tomsguide.com/us/what-is-mesh-wifi-router,news-24580.html

"With a mesh Wi-Fi router, one access point acts as the router or base station and connects to one of the best cable modems to get internet access. Meanwhile, the other nodes act as satellites, receiving internet from the base station and then rebroadcasting it to nearby devices.

All of these units share data back and forth and provide multiple sources of Wi-Fi. One of the best things about a mesh system is that unlike with Wi-Fi range extenders, they all share the same network, so you won’t have to switch to a new network as you move throughout your house."

I used to use simple extenders but keeping everything straight was a PITA. Not to mention all the SSDs to deal with. Messy. With mesh, you're not moving from one network to another. The handoff from one node to another is seamless.

Happy listening.

Please don't take what I say as gospel, it is merely my experience.

Several have extolled the Asus Ai Mesh system and for what I have found is good reason: It works. It is easy to set up and tune and provides excellent coverage. We have one base router and two extenders. The router is upstairs in my office as I spend a lot of time there and it's easy to cycle the power on the network should I need to reset anything. It's also easy to log into the nodes via my PC or the app on my phone for firmware upgrades.

One extender is in my wife's office. It supports her work PC, her VOIP phone and coverage out to our gazebo. Makes it easy to stream music out there or control my BBQ smoker via wifi. 😉

The other extender is in our living room. It supports my Bluesound Node2 and sits across the room from the hifi. Note: Any wifi appliance will be "noisy" and can upset sensitive stereo gear. My CJ phono preamp was unusable! So the extender was moved and lives in a bookcase about 15' away then I ran Cat8 to the Node. I also shut off the LEDs on that node. No need to have them on. Voila! Clean, dependable streaming. No drilling. No one drilling holes, etc.

Some may denigrate using ANY wifi at all however consider this: Think about where the signal is coming from. Where on the planet is the music server originating and how many hundreds (thousands?) of hops between switches, etc. has it had to make before it reaches you?? 

Happy listening.

@balooo2 mesh is NOT daisy chaining... Here is a better explanation, please see "Star topology versus daisy-chain topology":

The two really are fundamentally different. OTOH if you're comfortable with your simplification, though inaccurate, far be it from me to convince you otherwise. After 40+ years as a software professional, I've learned when to stop arguing.

Happy listening.
