Same thing happened to me this morning. Everything working as usual yesterday, but this morning "No Connectivity" on WiFi or Bluetooth. Tried reboot without success. Unable to reconnect my cell -- MCU display reads "Initializing" with spinning circle icon for over 15 minutes without ever initializing.
