    wireless problem firmware? driver?

    Hi!

    I have installed Ubuntu 11.04 on my laptop. For some reason Wireless Network does not work, only LAN cable connection works.



    lspci says:

    Network controller: Broadcom Corporation BCM4318 [AirForce One 54g] 802.11g Wireless LAN Controller (rev 02)




    System->Administration->Additional Drivers doesn't list anything.

    Can anybody help me? Thanks for any suggestions

    Hi, run this command please then disconnect you wired connection after it is finished and restart your computer.
    Code:
    sudo apt-get install b43-fwcutter firmware-b43-installer
    Now it should be working if so please use thread tools and mark as solved.
    Thank you
