Hi, i have 2 play1 in stereo mode, playbar and 2 play1 in surround mode, and a play 5. After adding the last 2 play1 to work with playbar, everything is unstable. One play1 in surround is not working. The stereo pair is in and out. All is messy. I have an extender and a wireless router. Is IT possible that some speakers is connected to extender and some to router? How do i make sure all are connected to one access point?
