I did another experiment. I've remove ehternet cable, connected WiFi to my home router. Now I could reboot as much as I want, WiFi worked, checkbox is visible and is ON inside network manager widget.
BUT, later I disabled WiFi connection, attached etherne cable, rebooted and that's it - wlan0 device missing, no WiFi checkbox! -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1585886 Title: WiFi indicator icon disappears in Ubuntu 16.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/indicator-applet/+bug/1585886/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
