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

Anyone use two Apple AirPort AirPort Extremes as a WiFi mesh setup? One hardwired to the router & communicating with a second in their audio room? That's what I use with quality cat 8 cable. Wondering what, if any, the limitations are in this type of mesh network?

So many people commenting, so few facts and so little knowledge, really sad.

First, Wi-Fi is wireless Ethernet. So the medium changes. But the same protocol.

Second, properly designed Wi-Fi can support almost all applications, outside multi-gigabit transfers and systems they use. 

Third, Cat8 cables are made for 10G and above, and so far no consumer grade streamer supports those speeds.

Fourth, a fundamental concept of Ethernet is that as long there is stable connection, your data is transferred 100%. 
 

Fifth, streaming from Qobuz, Tidal, and others are actually not streaming, they are download at maximum available speed, and then that song is stored in a cache for future playback. This fact alone 100% invalidates any and all “Ethernet upgrades”.

Thanks for this, I am a 100% with you.

The OP says that 'his' wifi has no dropp outs. Therefore, no need to change anything.

BDW, I am using both ways, cable and wifi to hear music from Quobuz. I cannot hear any difference in sound quality.

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

My two cents, as someone who has worked with Ethernet for almost 40 years, put in a good WiFi 6 mesh router setup, put a good network analyzer on your phone and learn how to assign WiFi to unused channels that give you good signal strength. That is the state of the art.

The Asus Ai Mesh system does exactly what you mention above regarding assigning signal strength.

You are also 100% correct songs are stored in a cache. To prove this if streaming music and someone sitting next to you watching video on an Ipad etc. asks "do you have an internet signal?" and 30 seconds to a minute later your media cuts out also. That is the cache dynamic in play.

 The world is going wireless most new home builders are not even offering Eternet wiring on build playlist anymore because most don’t find value in it. In 5-10 years this will seem like a silly conversation. Most younger folks under 25 don’t even know what Lan is.
