Hi. Got my first Sonos Speaker and problems from very begining.…

1. Connectig via wifi via Sonos app and can't do it. After "conecting' app shows notification, than speaker has been conected but can be not visible in device list, and if that the case, than should turn off the speaker, turn it on again and set uo mode and add it, but once doing it, nothing hapens, no device being found. 

2. Should I be able to connect Sonos via bluetooth without earlier setting up / connecting speaker via wifi ? If I try to change the mode via mode button to bluetooth, than no blue light appear, always white one.... 

Pls help as Im thinking about returning the speaker to the shop and broken one…

Thank You!
