Streaming: WiFi or wired??

The following thread will be of interest:

The bottom line to my three lengthy posts in that thread is that I agree with what @mike_in_nc said in his post above.

It depends. 

WiFi works just fine if your signal strength is good.  For a system the level of using the Kii Three I would look at the Aries G1 or G2 then you have the option.

I started off wireless and soon got tired of losing the handshake. Much more satisfying experience running Cat8 from an Ubiquiti switch. I think BluOs is the worst of the three player OSs that I have. In it's favor it auto indexes locall files and it plays any service without requiring plugin.
I just ordered a 4th streamer that looks like a game changer. Maybe August.

Bluesound wireless code is a trainwreck.  The Node 2i I'm trying out drops off the wifi network every few hours requiring a reboot to show back up.  No issues with any other wifi components on the network.  After conducting some research, this appears to be a long standing problem which Bluesound has failed to fix (among other wifi issues).  If you're getting a Node 2i (which is otherwise a nice fully featured streamer at the pricepoint) expect that you'll need to hook it up wired.
