Wifi icon on top panel disappears for me as well (16.04 + Unity). I have to use settings > network to deal with the WiFi connections. Happens mostly when I " suspend " and resume my PC.
I do not use an ethernet cable. So, unable to comment on that. sudo service network-manager restart nm-applet These commands, when active on terminal brings back the icon. But, the WiFi network listing are missing at times. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/1585886 Title: WiFi indicator icon disappears in Ubuntu 16.04 Status in indicator-applet package in Ubuntu: Confirmed Status in network-manager package in Ubuntu: Confirmed Bug description: Dear all, Can someone confirm an occasionally missing WiFi indicator tray icon?
