Wifi6 can do 1.2Gbps and most home ethernet is 1.0Gbps.
If you are streaming say hi-res Qobuz which is a few hundred kbps typically (max is 9216kbps theoretically for lossless hires but never achieved) and wifi6 does 1200000 kbps then just do the math.
Saying wifi cannot support music streaming is simply false and misleading to those searching out help.
