    Did a clean install of Ubuntu 12.10. Installed all updates (via cable). Installed the b43 drivers as described here. (My wireless card is BCM4322)

    Then I did the modprobe commands you suggested. It leaves an error message:

    FATAL: Module wl not found.

    … just thought you ought to know.

    • Hi Johan,

      Try Restarting your system.

        • Hi Mariajose,

          If it doesn’t work then you have to compile the driver source and install it.

    Great Stuff. Just to note, for people with the broadcom 4312 LPPHY chip, they’ll have to use the firmware-b43-lpphy-installer.

    I tried to install the firmware and fwcutter drivers and I get a note on the terminal that the files couldn’t be located. What do I need to do at this point?

    • Doug Bohrer

      Buy a Wifi or Ethernet dongle for $10-20 and do something more fun.

    addition driver showing error “This device is not working ” No proprietary driver in use

  • Kkuja

    It’s kind of absurd to assume working network to fix broken network.

    • Smartest OneHere

      Just imagine a you’ve plugged a network cable into the laptop…..

    This is wonderful. EXCEPT IT ONLY WORKS IF YOU HAVE A WIRED CONNECTION! The whole premise of looking for “Help”? with an issue? Is to give advice on all facets of an issue! Not just ONE scenario! How would someone who DOESN’T have access to a wired connection download the files needed? Can anyone elaborate? (Sorry for the “spicy” rhetoric…but I have a friend who has been trying to deal with this for over a MONTH! How can we expect people to be so ready to move to Linux if the assistance is sparse or only “half” full of information?

    • Logan Eastman

      You would have to do what anybody who doesn’t have working wifi does. Find somewhere with a wired connection. If he has been trying for weeks you would think that one of the solutions found EVERYWHERE would be to go to a library or workplace or friends house.
