Is that such a hard thing to ask Sonos to provide ?

As long as your router is broadcasting IP addresses, you should be fine.
I have a separate modem and router. A few weeks ago I had to switch off the modem for a full day to do some maintenance on my network, meanwhile SONOS was playing my music from the NAS without interruptions, and could be controlled via the iPad and iPhone without any issue.
