I am facing a similar issue in my HP Ubuntu 16.04 laptop... WiFi icon is grayed out, it doesn't show the active connection (though it is actually connected to my WiFi router!) and it shows other Wi-Fi networks. Sometimes, the whole icon disappears and I get the small icon of network (with the up-down arrows)!
As reported by others, I suspect that it is caused due to laptop going to standby. The "service network-manager restart" command worked for me! Wish this bug could be fixed though! -- 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
