Came across this thread yesterday and had to write about a similiar problem I have had for the past 6 months with my Sonos speakers (Ikea symfonisk)
I have narrowed down the problem to be a problem for my speakers to correctly reply to a dhcp offer.
I can see the problem in systemlog and even with tcpdump that the speakers correctly sends a DHCPDISCOVER and my router sends a DHCPOFFER but no DHCPREQUEST is ever sent from the speakers.
Instead the speakers resends another DHCPDISCOVER and router another DHCPOFFER in an endless loop. It’s like the offer never reaches the speakers.
My workaround for this problem was to setup a secondary dhcp server on a pc on the network to handle dhcp request for the speakers. It works great now but thats not how I want things to be. I would like the router to handle all dhcp requests offcourse.
And the sonos speakers are the only dhcp clients that have this problem.
Anyway when I came across this thread I tested to disable my two guest networks I have and BAM! The speakers reply to the routers dhcp offer.
This is so strange. There must be some setting somewhere that could fix this.
And by the way I have a BE86U router with guest network pro enabled with one guest network and a iot network. And I also should say that the speakers work fine with dhcp when connected to the iot network it’s only problem with the main network when guestnetworks are enabled.
