CD Ripper Ethernet conundrum

Unless I am misunderstanding you, what you are doing is using an WiFi extender to your Bluesound to get the same signal from your router you’d get if you could use an actual direct Ethernet wire to your Bluesound. Which is what I am doing since I cannot right now go wired ethernet from my router to the Bluesound. All those companies equipment work can work that way. It’s just not the best most stable solution. Let us know if I am misunderstanding what you are doing. 

We can get lost in the semantics for sure. Pictures help a lot for the old school folks like me lol.
All of the cd rippers with the exception of Cocktail require ethernet.
To the best of my *limited* knowledge, the solution is referred to as a "bridge". I tried "repeaters" with ethernet connections and failed.

The solution is not expensive and works great. All of these companies should offer the so called dongle and brand it as their own unique adapter

Thanks recluse, although the repeater I have is working well for me, I'm going to try a bridge for a more stable, and perhaps better sounding solution.

I think your question is whether the ripper can access the metadata by WiFi or is a wired connection necessary.  Bluesound works either way.  What the OP did was enhance his or her WiFi.
  I use Melco, which needs a wired connection. As for the other brands, read their product descriptions.  If they don’t have wireless capability, I wouldn’t try the square peg in the round hole thing and try to prove them wrong
