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

Ok, yes, @soix I was wondering about a mesh node or extender. Given that either of those also rely on Wi-Fi it would seem (on the surface) that this wouldn't really accomplish anything. However, I am wondering if a high quality ethernet switch between a mesh node and my streamer could result in better sound quality than just wi-fi to my streamer. 

This is a very interesting discussion. My goal is to get the best sound quality from my system. Given that I am currently running my streamer with wi-fi, it seems worth considering the cabling options that many say are superior. I haven't had any problems with wi-fi dropping out, so it's more a curiosity of what I may be unaware that I am missing and optimizing this particular link in the chain.

I don't expect a massive improvement from this, but even slight improvements at this stage are very satisfying. So thank you for sharing your thoughts and experience in this area. Sometimes I feel like I may be chasing my imagination, but it is a good time...so I keep doing it!
