    Another network card problem

    This is related to the Broadcom 43xx problem discussed in the sticky above. Hope this is the proper place to post.
    I have a Dell Inspiron 1150 with a Broadcom 4306 card. It worked with wireless fine in previous versions but has not since I installed (clean) version 12.04.
    I installed the B43 driver but when I try to install the firmware for it, the system crashes, leaving a long line of script on the screen. Something about "modprobe tainted."
    I have a Belkin USB stick that I can reach the Internet with and I suspect it might be causing a conflict.
    I could just continue using the USB stick but it irks me that I can't get the card to work as it did before. Have considered getting another card, since they only cost about $9, but I am doubtful that would help.
    Any suggestions appreciated.

    Ran the first command and got this:
    E: dpkg was interrupted, you must manually run 'sudo dpkg --configure -a' to correct the problem.

    Ran that command and it crashed...

    Re: Another network card problem

    OK. Problem solved. Apparently it was a conflict. I removed the USB device, downloaded the tar file, installed it via the terminal and now I am up and running and I can put away the USB device. For anyone with a similar problem the commands are:'
    tar xfvj broadcom-wl-5.10.56.27.3_mipsel.tar.bz2
    sudo b43-fwcutter -w /lib/firmware broadcom-wl-5.10.56.27.3/driver/wl_apsta/wl_prebuilt.o

    Additional information: It was only solved until I rebooted. Apparently the Belkin USB adapter installs its own driver, so I had to blacklist that one, remove the adapter and reboot, then run the commands above again, and add "sudo modprobe B43." Now we seem to be up and running again, permanently I hope.

    Re: Another network card problem

    Silly me. This is not solved (and I don't know how to unmark it "solved". Apparently the B43 driver got blacklisted somehow and I have to redo it on every boot. The file with the blacklisting can't be edited. I tried to purge bcwml, per the wiki troubleshooting guide and got this: E: dpkg was interrupted, you must manually run 'sudo dpkg --configure -a' to correct the problem.

    Every time I try to use that command, my laptop crashes. So, can anyone tell me how to un-blacklist the B43 driver for good?
    Also, some instructions say use B43 and some say use "wl." B43 works but do I need to mess with wl or ssb?

    Re: Another network card problem

    Hi, you can not use both wl and b43
    as the wl driver blacklists ssb and b43
    so....
    *If your command sudo modprobe b43
    works for you then you can do..
    Code:
    sudo su
    echo b43 >> /etc/modules
    exit 0
    this will load the b43 driver on boot or restart
    Also..if you have not already done so...please do..
    Code:
    sudo apt-get update
    sudo apt-get upgrade
    thanks.

    Re: Another network card problem

    Code:
    sudo rm /etc/modprobe.d/blacklist-bcm43.conf
    sudo rm /etc/modprobe.d/broadcom-sta-common.conf
    sudo rm /etc/modprobe.d/broadcom-sta-dkms.conf
    should do the trick

    Re: Another network card problem

    Help! This has now turned into a different problem that I'm certain is related. Now I can't update! update manager says something is broken. trying to sudo update in the terminal gets me the instructions do dpkg configure whatever which, as I noted above, always crashes my computer.
