Connecting to a Bluesound Vault 2i

You can get a wifi extender that has an ethernet connection and use that to connect the Bluesound to that, then the hotspot won’t disable the wireless. Hopefully you can connect the extender to the hotspot, it's easy with a router, not familiar with connecting them to a hotspot.

I will be sending mine back for refund. Apparently what the OP said above is true. Our hotspot disables wireless once Ethernet is used and connection via wireless is impossible with the VAULT since passwords are employed. 

OP here.  Here is what I have learned over the last two very frustrating  weeks.  You must connect the Vault to a Router via Ethernet.  The Vault and the controlling device containing the BluOS app (Tablet in my case) communicate via Wifi network.  Bluetooth is only utilized if you are streaming from your BluOS app device to the Vault.  You cannot control the Vault via Bluetooth.  Internet is only required for updates to the Vault.  I will be looking for other methods to get updates since I only use my Smartphone as a Hot Spot for internet connection, and I cannot connect my Tablet to my Wifi network and my Hot Spot (Smart Phone) at the same time.  If anyone has ideas, please let me know.  Can I connect PC to Vault via Ethernet, and PC to internet via Hot Spot?

Another challenge has been finding either the "Reindex Library" or "Rebuild Library" in the BluOS app.  They simply are NOT under the Settings - Music Library where they are supposed to be unless they are hidden.  I have the latest App and Vault.  Again, any input would be appreciated.  Thanks!

If the OP is using Bluetooth for playback from phone, etc., no WiFi should be needed. Streaming from the cloud services such as Tidal, Spotify, is a different story.

I am a little confused. The whole point of a Vault is to stream music. Yes you must have internet and a router to connect to the Vault.

@gdnrbob2 Yes, I reviewed Bluesound's support articles and contacted Bluesound several days ago, but no reply.

The reset sounds like a potential solution but somewhat scary on a brand new device.  My concern is that without internet access, the Vault will constantly be looking for updates causing the network to freeze up.

I don't have a problem with buying a Router if that will solve all issues, but I'm not convinced it will.  Yes, I am the last man on Earth without internet access, and now I am suffering for it.

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.

You need a Wifi network to connect to the Vault and control it with your tablet.

Perhaps others can chime in, but I think you need a router.

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?

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.

I use a Google Wifi router.

I just had a TeamViewer appointment with Maya to try to find out why I am having issues with Quobuz.
The best way to contact them is through the App.
Click 'Help', then 'Send Report Request'.

The Bluesound customer service has always been helpful to me when I had communication problems. The email is support@bluesound.com and the phone is 1-855-531-4666 M-F 8am to 7pm ET. The guy who helped me is Jon. If you have problems with connecting devices, software issues, connecting to a local network or NAS he can help. They can even connect to your network remotely.
Good luck,
