My laptop running Ubuntu/Mate will connect to WiFi, but I don't seem to have any way to get to a WiFi selector to choose from nearby networks. I have no tray icon showing signal strength, no "WiFi not connected" option on the System menu. Maybe related, I don't have a wlan0 interface. I suspect I am missing a package or have some setting messed up. Anyone got any ideas?

  • Ubuntu 18.04.1
