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.

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.  
I dont have my node anymore or else I would look through the app and help you get it configured to your wifi. Perhaps mental could chime in.
