I have a Sonos Boost network at work where we don't have a wifi network. I've always controlled the network (adding speakers etc) via my desktop controller. I've just updated my system and the option to manage it has been removed. Reading further I see the option to control via desktop has been removed. With no wifi I seem to be stuck.
So how do I add a speaker to my Boost system if I don't have wifi and so can't use the mobile app? Help!!!
