Connecting to a Bluesound Vault 2i


I know there are several Bluesound users on the forum, and I am not getting any support from Bluesound.  I just received an new Vault 2i and I want to control it using a Windows 10 Tablet.  I loaded the BluOS app onto the Tablet, and the Tablet has recognized the Vault.  However, the BluOS app will not open, or recognize the Vault.  Vault is flashing green which means "Looking for a Network".  Can I use this product without connecting to the internet?  If so how?  Do I need a Router?  Will a Router operate without internet access?  All I want to be able to do is connect the Vault to my DAC and control the Vault with my Tablet via bluetooth and the BluOS app.  I don't want to stream anything.  I don't to communicate with any other devices.  Any help, guidance, or clarification would be greatly appreciated by this challenged new user.  Thanks.

Welcome to the world of "Made in China". If you don't speak
Mandarin or Cantonese perhaps you want to buy US made.
I have had some very crappy or perhaps even non-existent
CS from the following companies: Tidal, Schiit. 
It seems today companies need to devise a logo 
of a person with a phone at the ear. This would be prominently
displayed on the box and on the back of the product and would represent
companies who have live, US based support available.
It counts to me anyway.
First of all, I apologize for posting under "Cables".  I meant to post under "Digital".  If anyone knows how to move a post, please let me know.

@2psyop I have already submitted a request for support and not heard anything from Bluesound.  I have no Network, and am trying to determine if that is my problem.

@gdnrbob  I am unable to even open the BluOS app.  I just spins and says "Looking for Devices" or something similar.

@pdreher So I do indeed need a Router?  I have no Network.  I have no Internet.  I will not be streaming to or from anything.  I want to hardwire directly to Amp/ DAC via Toslink, and control via BluOS app on Windows 10 Tablet via bluetooth.  What am I misunderstanding here?
You need a Wifi network to connect to the Vault and control it with your tablet.

I would try a factory reset.
I don't own the Vault, but I think it is holding down the button for 30 seconds until it changes color.
You can also get support via Bluesound Website.

There should be a little pop up at the lower right corner for support.
Click on it, type Vault, and it will list some things, but below it is a Contact Us button.
