Need help troubleshooting spotify

I have a blue sound node 2i  That used to  Stream spotify perfectly.  I got a different router from my  Internet provider and now Spotify doesn't recognize the node wirelessly or if it's connected by ethernet.  Spotify customer support is useless they blame blue sound and blue sound blame spotify meanwhile I can't stream music because spotify connect doesn't even recognize the node as an available device. I've tried powering off and on uninstalling re-installing, etc.  Nothing works. The ideas or experience to help would be appreciated. Thank you.
