    Are you sure Proprietary Drivers are enabled?

    Are you sure you have not made any edits in the IP configs? Set it to "Automatic (DHCP)".

    Do you have Windows installed? Does Wireless work in Windows?

    Are you sure your hardware switch for the Wireless Card is turned on (this feature may not be present in some computers) ?
