There is none out there......

This will do the trick and much less costly than the mesh. You just have to make sure they are on the same circuit. Not circuit as in circuit breaker but as I understand it in the USA there are 2 different zones (call them zones for lack of a better word) as long as the 1 near the router and the other are on the same zone this will totally work. You might have to try a couple of different outlets near your rig (I did and it connected)...

I've been very happy with my Cocktail Audio X50D - with both CD ripping and wifi performance. In my previous apartment I had it hardwired, now I'm running it on wifi. Not much difference. But, adding a nearby wifi extender with a cable into the X50D is certainly an option.

Good luck,

Not a fan of the AC / Ethernet adaptors. IMHO the pure Wifi to Ethernet adaptors are better. Have a single Ethernet cable you hook to your streamer. Use a phone Wifi analyzer first to ensure strong signal and that you aren’t competing with other routers on the same channels.  Also, these adapters only need a single unit to work, as opposed to one near the router and one near your streamer:

All you guys have really given me a bunch of options......Thank you all for your suggestions......Now I've just gotta' go do it!

Hifi sales people think you should spend more? Will wonders never cease...

I have 2 Bluesound Nodes and they work very well, sound great and the app is nonpareil. Try it first, at least, to see what you think.

BTW, I use a Simaudio Moon 390 in my main system, but the Node is no slouch. The Mind 2 app is not nearly as good.
