Upgraded to 12.04 and now the WiFi applet doesn't show wireless connections to connect to

Question

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.

Answer 1

The problem might be that your Wireless Card isn't being detected, or needs restricted drivers to work properly.

Try to connect thru ethernet to the internet, open a terminal window and type:

sudo apt-get update

and then:

sudo apt-get upgrade

it updates your system.

Then, go to System Definitions > Hardware and open Aditional Drivers

It should open a window with the restricted and opensource drivers for your wireless board. You just have to select and activate the one that you want.
