Comment 18 for bug 1638842

Same problem after an upgrade from 16.04 to 16.10 via "do-release-upgrade". However in my case the issue occurred not for Ethernet or Bluetooth, but for Mobile Broadband (device ttyUSB2 of type gsm over interface ppp0). So, the changelog comment 'we definitely want NM to manage wifi and mobile data' is not really holding. Could it be the author erroneously supposed mobile data is only transferred over the wwan interface? In that case, the issue should indeed be fixed.
