I have just started using Ubuntu, and have always been using windows, so I am a bit of a newbee here.
I installed the 12.04 Precise Pangoline version the other day, and everything seem to work fine, except for the fact that the wireless network doesn't seem to work.
When I go to System Settings --> Network --> Wireless I can't move the bottom to "On". And when I turn Airplane mode off, it automatically sets it back to on when I leave the menu.
I have Windows 7 running on another partition and here I can access the wireless network without any problems.
I am using a Dell Vostro 3450.
