I installed the Deco M5 to fix issues with the wifi on my router. I have moved the connections for my SONOS speakers from the old wifi to the new wifi which now has new ip addresses, lets call that HOMEW. Issues is that I have a NAS for my music library which is hard wired into the exiting 10.x.x.x network (HOME). The SONOS application can not access the NAS. I also lost connectivity to the Sonos system from my workstation (HOME). I think from reading that I want to switch the DECO from ROUTER to ACCESS POINT. Just not 100% sure. I have an Ethernet cable that goes from the modum to the M5, I could move the Ethernet cable that goes from the modem to my switch and connect the switch directly into the M5. Everything would be on the HOMEW network, just not sure if that would drop the speed or cause other issues.
