I recently read that the Sub should not serve as the "wired" component for the network so have decided to change to a Play 5 in another room. I unplugged both the Sub and the Play 5 from power, then removed the ethernet connection from the Sub and connected the Play 5. I then powered them both up. However, when I check "About my system" the Sub still says WM:2 and the Play 5 is still WM:1. Am I doing something wrong?
