    No wireless in 9.10 with Broadcom BCM4312

    Hey Guys,

    I'm having some problems with 9.10 on my Dell Mini 9. I'm a bit of a new comer to linux so if it's something obvious I apologise. If you can help me out thanks in advance.

    Basically I'm not getting wireless as an option in the little network drop down thing. (very technical description )

    I've tried some of the suggestions in this thread:
    http://ubuntuforums.org/showthread.php?t=1309760

    Well the following commands from that thread:
    sudo apt-get upgrade
    sudo aptitude reinstall bcmwl-kernel-source
    sudo apt-get install update
    The Broadcom STA driver now shows up in Hardware Drivers however has the following message at the bottom:
    The driver is activated but currently not in use
    sudo lshw -c network:

    I'm guessing that UNCLAIMED bit probably is causing the problem. However I know nothing.

    EDIT: I also just thought it might be worth mentioning. I couldn't get ubuntu to boot when using the usb-creator.exe. I created an USB drive with unetbootin and install was successful.

    Cheers

    If you'll post the relevant Network Controller section from

    sudo lspci -vvv

    we can look at the available and currently used drivers.

    Re: No wireless in 9.10 with Broadcom BCM4312

    You just need to activate the wl kernel module (the STA driver). Did you reboot after installing? It shouldn't be necessary, but mine did not work properly until i did. Even if you haven't go ahead and try to load it manually:

    sudo modprobe wl

    Running

    lsmod|grep wl

    should show wl and ssb loaded afterward. Then check to see if the network interface is up with

    ifconfig

    The wireless should be eth1 or eth2.

    Hey,

    I've tried restarted a fair few times.

    The modprobe command returns this:

    FATAL: Error inserting wl (/lib/modules/2.6.31-14-generic/updates/dkms/wl.ko): Unknown symbol in module, or unknown parameter (see dmesg)
    Found this info on the message:
    https://bugs.launchpad.net/ubuntu/+s...ey/+bug/449268

    Tried:
    sudo apt-get install bcmwl-kernel-source - Was already newest version

    depmod -a - no change

    dmesg error:
    [ 4230.435376] wl: disagrees about version of symbol lib80211_get_crypto_ops
    [ 4230.435390] wl: Unknown symbol lib80211_get_crypto_ops
    .

    Re: No wireless in 9.10 with Broadcom BCM4312

    Someone elsewhere suggested checking the wifi was actually enabled.

    Installed aircraft-manager and it does appear to be running.

    Still no progress with it been usable though.

    Has also been suggested trying this patch:
    https://bugs.launchpad.net/ubuntu/+s...24/+bug/252630

    Will update with result once they're able to help as have no idea how to apply it. However have also been told that it should already be in 9.10.

    Thought ubuntu was meant to be easy.

    Update:
    Have now also tried moving maximus-autostart.dektop from /etc/xdg/autostart to my home directory as suggested here:
    http://ubuntuforums.org/showthread.php?t=975498&page=2

    Want to try adding wl to /etc/modules as suggested in that thread but don't have a clue how.
    EDIT: Just realised this is what we were trying to do with modprobe.

    Re: No wireless in 9.10 with Broadcom BCM4312

    Tried the following from this thread http://georgia.ubuntuforums.org/show...&postcount=18:
    Which was found via this bug report:https://bugs.launchpad.net/ubuntu/+s...wl/+bug/395630

    I've removed linux-backports-modules-2.6.31-1-generic as suggested in the bug report. I also deleted the lib80211.ko files as they were still causing the unknown symbol error. However now those files are gone I'm still getting an error saying that it's got an unknown symbol in that file. Even though it doesn't exsist any more.

    I'm thinking about just installing .04. Is the wireless likely to work there?
    Also should I maybe try ndiswrapper.

    haha. It should work NOW. BCM4312 works for me with bcmwl. Did you try the insmod instructions in bug 395630?

    Still nothing. haha I'm running 9.04 off USB now and it's working great. Guess we may aswell try and get 9.10 going though.

    How do I check if I have any backports installed?

    Run

    sudo dpkg -S lib80211.ko

    This will list any packages containing the module in question. if you have backports, or anything other than the linux-image package which contains it, you'll see it listed.
