    Broadcom 4311 wifi card not working with Ubuntu

    First forum, please go easy

    I just installed Ubuntu 12.10 on my Dell Inspiron E1705 and everything works great except the wifi is not working. I am currently using a wifi usb that is allowing me to use the internet.

    Still looking around for some help through other threads, but not necessarily confident with any of them.

    Help would be greatly appreciated! I love ubuntu and don't want to switch back to Windows because of the wifi issue.

    Happy threading!

    Have you tried to, while connected via ethernet or USB
    Code:
    sudo apt-get install b43-fwcutter firmware-b43-installer
    And once completed
    Code:
    sudo modprobe b43
    Then try to connect?

    This is what I recieved after the sudo apt-get

    sudo apt-get install b43-fwcutter firmware-b43-installer
    E: Could not get lock /var/lib/dpkg/lock - open (11: Resource temporarily unavailable)
    E: Unable to lock the administration directory (/var/lib/dpkg/), is another process using it?

    That usually means you have synaptic or update manager open at the same time.
    Those 2 apps & apt-get all require exclusive access to same files.

    I have this written down from BCM4312 wifi issues kernel 3.5 & *buntu12.04:
    The first 6 lines is debugging stuff to help you & others..

    Code:
    cat /etc/lsb-release; uname -a
    lspci -nnk | grep -iA2 net
    nm-tool
    iwconfig
    rfkill list all
    lsmod

    If your card number is: BCM4312, then type in a Terminal window:
    
    sudo apt-get purge b43-fwcutter firmware-b43-installer firmware-b43-lpphy-installer firmware-b43legacy-installer bcmwl*
    
    sudo apt-get install b43-fwcutter firmware-b43-lpphy-installer bcmwl*
    
    Then reboot
    My BCM4312 is using wl driver (modified source code 2 lines)

    OK, make sure you have software center and the package manager closed and follow these steps.

    make sure you have dkms installed first.
    In a terminal type:
    Code:
    sudo apt-get install dkms
    Here what to do next.
    1. uninstall “bcmwl-kernel-source” package,
    Code:
    sudo apt-get remove bcmwl-kernel-source
    2. install “firmware-b43-installer” package
    Code:
    sudo apt-get install firmware-b43-installer
    3. install “b43-fwcutter” packager
    Code:
    sudo apt-get install b43-fwcutter
    4. type into the terminal:
    Code:
    cat /etc/modprobe.d/* | egrep '8180|acx|at76|ath|b43|bcm|CX|eth|ipw|irmware|isl| lbtf|orinoco|ndiswrapper|NPE|p54|prism|rtl|rt2|rt3 |rt6|rt7|witch|wl'
    This was the out put:
    Quote:
    # which ath5k cannot recover. To prevent this condition, stop
    blacklist ath_pci
    blacklist eth1394
    # replaced by p54pci
    blacklist prism54
    # replaced by b43 and ssb.
    blacklist bcm43xx
    blacklist uart6850
    blacklist twl4030_wdt

    At this point you may have to restart your computer.
