I have over 20 Sonos speakers connected in various rooms to a 5 GHz Wi-Fi system. The frequently will not connect. But the next day they will. It’s intermittent and a reboot Of the local ethernet switch normally solves the problem.. Question: would it be better to switch to the 2.4 Gigahertz Wi-Fi network which I already have set up? If so, how do I do it?Gigahertz Wi-Fi network which I already have set up? If so, how do I do it? Would I have to go and restart each and EVRI Sonos speaker by reconfiguring it?
