After almost two years, I suddenly lost the wifi connection to my Sonos Beam. I have tried restarting the router and factory resetting the Beam. When trying to reconnect the Beam, it is unable to find my wifi network. I understand this might sound like a 2.4/5.0 Ghz issue, but I have another Sonos Beam in the house that I am not having any issues with. Furthermore, I haven’t made any changes to the wifi settings on my router and don’t know why this would suddenly become an issue. During setup, the app does list other wifi networks in the neighbourhodd, but cannot see mine.
