I upgraded Ubuntu to 12.04 and everything is fine expect I now have no option to connect to WiFi.
Under the WiFi applet in the upper top right where I would typically open the applet and see WiFi signals that the computer finds and that I can connect to, when I open the applet there are no Wifi signals listed to choose from.
It shows from top to bottom in white text: VPN Connections, Enable Networking and Edit Connections; it shows in dark text that I can't open: Wired Network, disconnected and Connection Information.
Any ideas what to do? Basically the computer software doesn't show the option of connecting to the WiFi now.
