BlueSound Stinks(!), anyone?

I am looking for your help.  We recently switched from Sonos to BlueSound to get higher streaming rates.  So far we have had consistent problems and issues(!!).  Specifically, about 50% of the time my and my wife's BlueSound app does not recognize the Node 2i's.  When I delete the app, reinstall it and reconnect the Nodes, we again have the same problems at least 50% of the time.  It is simply a joke of a product and I find we are not alone.  I have tried just about everything.

Also, when I go online to get help, I find that I am not alone and there is a tsunami of negative (to the degree of very hostile) comments about BlueSound and for the most part it is the same issue.  I have tried just about everything and I am about to simply trash/sell mine and go back to Sonos.  If I do go back to Sonos, I will also leave a stream of bad comments on every forum I can since going back to Sonos will represent a big financial loss to me simply because Bluesound is an irresponsible/deceptive company at my expense.

Alternatively, I just want it to reliably work.  Do you you have and advice and/or guidance to get Bluesound to reliably work?  Is there a better alternative to to get higher bit rates thank Bluesound?

Thank you in advance for your help.  Dave

Node 2i here. Had a problem after one of their updates with my PC's app.  Sent them a help request. Their service responses were ASTOUNDINGLY GOOD.  I know, all caps but it really was as good as it gets.  Stayed with me until we found a workaround.  Yes, my DAC sounds better than their built-in one and yes, the app could use some tuning. And yes, I'd like a "remote without a speaker" to use with my other audio systems.  But wow, great support when I was at wit's end.
I have a Vault 2.  Never had a problem with it.  My only gripe is that it only connects over wired network.  I had to get a wifi extender setup that offers an RJ45 ethernet port over at my stereo area. Other than that it's been great. Phone app works well too.  I tried a Sony player that connected wi-fi but it was not reliable. Eventually had to hard wire it too.  I sold it because the Vault 2 has a better app.
I would tend to think the naysayers are the minority.
I’ve been a happy BlueSound user for at least 5 years.  Good sound at the price point and the  ergonomics are great and app operation has been glitch-free wirelessly with my Node devices thru my apple iPad.
As others may have eluded to... your WiFi might be the issue.  If so consider going the hard-wire Ethernet cable route or address whatever shortcoming might exist with your router.
