I reset the controller to no avail. I attempted to reconnect the beam with the button near the power input, which also was unrecognized on the app.
I am now connected to my router via Ethernet and the Beam works. I followed instructions to the Wireless Setup page on the Sonos app and my wireless network is not visible. I manually entered the details and the app states there was a problem connecting to my network.
This is a 2.4 GHz network and the Beam was able to be set up the first time without issue using this network. I only have 2 other devices (iPhone and iPad that use the controller app). I want to use the wireless network features for AirPlay2 support.
