Bluesound Node 2i Question

Just bought and set-up a Node 2i.  Set-up was real a pain, but after that, it works great and sounds pretty good.  My question is about streaming. We set it up with BluOS on an Ipad.  The Node is connected directly to my amp via analog RCA.

Is the music streaming from my router to the Node, or is it streaming from my Ipad to the Node?    I would have expected to enter my router password, and this was not required in the set-up process.
There are a few ways you can set up the node so I will try and clarify my previous post.

First in order to stream from a NAS or online music services such as Tidal, Deezer etc, you must connect to the internet. You can do this by hard wired Ethernet from your router or wirelessly in which case you will need to enter your wifi info and password.

If you wish to use Spotify, the app is not built in to the Node like Tidal but you can utilize Spotify Connect. This requires wifi, but it will hand the stream off to the Node. However you still have to open the Spotify app separately fromthe BluOS app to control it. 

All other music services not supported by Bluesound and or music stored on a device you would use Airplay or Bluetooth.

For Airplay and Bluetooth the stream is casting from your device to the Node, no wifi connection is necessary. This is a nice feature that I did not think I would need until rolling blizzards knocked out our internet. I have an Ipad with it’s own unlimited data plan so I was able to stream from my music services as well as music I have stored on it. Very handy.

Hope this answers some questions.

Yes set up is a breeze. I am curious to know your thoughts on the user interface.

Ethernet cable hardwired to the router was not feasible in my case.  We are using blueteeth, so I have a feeling its streaming from my ipad.  

The user interface is just fine in my opinion.  The only problem I see with the unit is the blue light staring at me. I might need to duct tape it.
