    have you checked that your wifi device is compatible with linux?

    if found this website useful when building my pc http://www.linux-drivers.org/

    you could try searching your make/model of card on the ubuntu forum and see if anyone has had problems/success in getting it to work.

    Your router is irrelevant.

    We need to know what hardware your computer uses

    Open a terminal on the laptop ("Applications->Accessories->Terminal)

    Then enter:
    Code:
    sudo lshw -C network
    Then post the output here, that should tell us what hardware your laptop uses.

    Next enter:

    Code:
    ifconfig -a
    and post the result here.

    Finally, could you tell me if you have a an option for "enable wireless" present in the right click menu of the networking icon sitting in the notification area.

    if the icon is still missing, it will probably come back by restarting X (ctrl+alt+backspace) or you can run nm-applet in a terminal.

    Have you tried a simple left click on the network icon in the systray (top right).

    I thought the broadcom BCM4318 worked out of the box. I may be wrong?
    Hmmm...

    This thread should get you up and running:

    http://ubuntuforums.org/showthread.php?t=190177


    Just remember that when you buy a laptop, the manufactures install the drivers for your hardware. This is not a problem with Linux rather the problem is with the lack of support for Linux coming from hardware vendors.
    Hmmm...
