  1. Best Answer

    I have BCM4312 wireless card too.

    What I needed to do:

    1. Go to: System->Administrator->Additional Drivers(Hardware drivers)

    2. Then click to Broadcom STA wireless driver and enable it.

    3. Restart

    To me it's the easiest way.

  2. The STA driver in 11.04 doesn't work due to a kernel issue. You will have to install the B43xx firmware. Just install firmware-b43-installer from the Software Center or Synaptic.

    You can also do it from the command line: sudo apt-get install firmware-b43-installer

  3. Well I have Broadcom 4312 wifi and installed the sta driver using the terminal

    Click the dash, type 'terminal'and issue the following commands:

    sudo apt-get update
sudo apt-get install bcmwl-kernel-source

    It worked a treat, first time on a new install of 11.04

    Hope that helps

    This is what it looks like to use

  4. I followed the Medieval's steps, but (for me) it was incomplete.

    Then I had to go to System Settings → Additional Drivers → then Activate the wireless card.

    Then up in the menu desktop, I clicked Enable Wireless.

    I hope this helps somebody.

  6. There's no need for ndiswrapper and Windows drivers, because the Linux driver already exists,

    • if you see no broadcom wireless device name, uninstall driver, restart computer, install driver and restart again until "firmware missing" message appears with wifi device name under wireless icon after clicking on it (gnome).

    • If you haven't it, you must install a synaptic package manager from Ubuntu software center

    • search "bcm" inside synaptic package manager

    • mark for installation "b43-fwcutter", "firmware-b43-installer" or "firmware-b43-lpphy-installer"(if you have a broadcom lpphy driver), "firmware-b43legacy-installer" and apply, no restart needed. Your Wi-Fi led turns on immediately.
