    Wireless modules blacklisted after update (12.04)

    I was prompted to update today, but something went wrong. It didn't fully update and when I restarted, all I got was a black screen. So I rebooted into "safe mode" and finished the update, but when I restarted my wireless wasn't working.

    I checked http://help.ubuntu.com/community/BroadcomSTA(Wireless) and made sure I had the right drivers installed. After making sure the bcmwl-kernel-source package was installed, I went to the Additional Drivers page and tried to install the STA drivers. It didn't work. It told me to check /var/logs/jockeylog for what was wrong. Here's what I saw:

    PHP Code:
    2012-10-10 21:24:23,312 WARNING: /sys/module/wl/drivers does not existcannot rebind wl driver

    -10-10 21:24:52,744 DEBUGBroadcomWLHandler enabled(): kmod disabledbcm43xxblacklistedb43blacklistedb43legacyblacklisted 
    So, no wireless still.

    Here's the rest:

    Dell 1545 with a the BCM4312 wireless card. "lsmod" shows no wireless modules and "iwconfi" shows no wireless extensions. I'm running Ubuntu 64-bit with the 3.5.0-17-generic kernel. Also this:

    PHP Code:
    sudo /etc/init.d/networking restart
     
    Running /etc/init.d/networking restart is deprecated because it may not enable again some interfaces
     
    Reconfiguring network interfaces... 
    I have no idea what updates were trying to install when all this broke. I've also replaced network-manager with WICD. Any help is appreciated.

    Re: Wireless modules blacklisted after update (12.04)

    I tried everything I could find on this forum and on AskUbuntu and finally decided it might be due to installing Gnome Shell, Cinnamon, or the full Kubuntu suite. After fully uninstalling every little app, widget, and library, still nothing worked.

    So, I backed everything up and reinstalled. Hope you get some help. I don't know if this forum is just that dead or what, but I don't have time to wait days without wireless.

    FYI, there's a lot of threads in this forum and on AskUbuntu with lots of things to try. In my case, I think it was related to having installed the full Kubuntu desktop complete with all libraries and apps. I had uninstalled network-manager and replaced it with WICD and that could have been part of the problem as well.

    Good luck!

    Edit: I don't know if it'll help now, but here's what was asked for (from my now working re-install)
    Code:
    0c:00.0 Network controller [0280]: Broadcom Corporation BCM4312 802.11b/g LP-PHY [14e4:4315] (rev 01)

    It's amazing the urban lore that gets spread around and accepted as gospel. It's not your fault. The ONLY reason is that you don't have the correct driver/firmware combo for your device. All the Gnome/Unity/NM/Wicd is red herring and guesswork on the part of the post answering 'experts.'

    Please do:
    Code:
    sudo su
    apt-get remove --purge bcmwl-kernel-source
    apt-get install firmware-b43-lpphy-installer
    echo b43 >> /etc/modules
    exit
    Reboot and let us have your report.

    WARNING: misfit815 and other searchers; unless your device is also Broadcom Corporation BCM4312 802.11b/g LP-PHY [14e4:4315], the fix may be different.

    Let's see:
    Code:
    sudo modprobe b43
    dmesg | grep b43
    Thanks.

    Re: Wireless modules blacklisted after update (12.04)

    Yup. Went something like this...

    Code:
    sudo apt-get remove --purge firmware-b43-lpphy-installer
    sudo apt-get remove --purge firmware-b43-installer
    sudo apt-get install firmware-b43-lpphy-installer
    And now I'm back on wireless. It looks like whatever was updated the other day somehow hosed something associated with the lpphy package, and removing and reinstalling it took care of the issue.

    Thanks.
