    First check here:

    As you can see, your fist thing to test is:
    Hot Keys: -Fn+F2 Wireless switch

    If that not works, can you provide more information about your system, what Linux distribution are you running?
    If you don't know test to run "lsb_release -a" and "uname -a" in the terminal.

    Also you can test to run "iwconfig" in the terminal to get some info.

    Try what Aron said, but also, if the device merely needs to be started:
    ifup wlan0

    ifconfig wlan0 up

    also, check the BIOS for a wireless device setting that maybe disabled.

    On my Dell laptops, I have physical switches. One is an led light that I have to touch, the other is a toggle switch, make sure yours is enabled. As said in the posts above, it could also be a setting in the bios, but, on modern day machines, there should be a physical switch.

    If you could give us the output of:
    lspci | grep -i net
    We can see what adapter your using and give you additional help.

    BTW - With the different outputs for wifi adapters, if lspci | grep -i net does't give you any output, try:
    lspci | grep -i wire
    lspci | grep -i wifi

    The more help you give us, the more we can give you.

    Well broadcom drivers are proprietary and so do not come embedded in Linux. Have you tried installing the broadcom-wl driver? It should be in one of the Ubuntu repos, I can't remember the proper name for it, but it would be the one that contains the non-free software.
