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.

@gdnrbob-I had two call backs from Bluesound, the first they left a message on my voicemail, the second call i answered and the guy did remote assistance on my Imac and fixed my issue, so far. If the problem rears its ugly head  again then he told me to call him and he will give me a list of ethernet boxes they recommend. So far, its been a day and I am happy to say it is working great. I will now say their support service is good. 
 When I first was setting up blue sound ball to I called tech-support a number of times. Is that an email. I never got a response. Was hugely disappointed! I sold my bulk to purchased  M50.2.  Set up was-easier The second time around 
Ah, the mysteries of set up: tried a Lumin D2 and it never worked with Tidal (copious dropouts with either ethernet or WiFi) but Node 2i was up and running in less than 5 minutes. Interface is far superior to Lumin, which had no support available. Wish I knew why such oddities occur.
