Years ago I experienced an issue with a Cyberpower UPS software update that interfered with the system's Bluetooth, causing devices to not be able to connect, inexplicably since the software doesn't use BT for anything. Only after much online searching did I stumble on another user with the same issue and after uninstalling it and reverting to an earlier version the issue immediately went away. I've since kept a more open mind as to what may be causing network issues.
