    Re: Broadcom BCM4313

    Alright then; here we go. Ideally with a working wired ethernet connection, download this to your desktop: http://www.kernel.org/pub/linux/kern....13.2-1.tar.xz Right-click it and select 'Extract Here.' Open a terminal and do:
    Code:
    sudo apt-get install linux-headers-generic build-essential
    cd ~/Desktop/backports-3.13.2-1
    make defconfig-brcmsmac
    make
    sudo make install
    sudo modprobe -r brcmsmac
    sudo modprobe brcmsmac
    You may get a warning about signing that you may safely ignore. It may take a reboot.

    Any improvement?

    This looks promising! The wireless connected at the login screen, and didn't disconnect after I'd logged in. I'll leave it running and post back here if it disconnects.

    Thank you!

    It's now disconnected, which looks like it was up and running for about 5 minutes. If you had any more input I'd be very grateful. Thanks for all your help so far.

    Re: Broadcom BCM4313

    Thank you for being our test pilot! We strive to find a workable solution for every device and, so far, I think we only know what doesn't work! Let's try a completely new approach. Please do:
    Code:
    gksudo gedit /etc/modprobe.d/blacklist.conf
    Change the blacklist wl line to instead blacklist brcmsmac. Proofread, save and close gedit.

    Now do:
    Code:
    sudo apt-get install bcmwl-kernel-source
    When it finishes, immediately reboot, cross your fingers and hope!

    We are quickly running low on ideas/mojo/talent.

    Re: Broadcom BCM4313

    I have the same card and actually brcmsmac works really well. I have purged bcmwl-kernel-source and removed the blacklist file it generates.bcmwl-kernel-source blacklists brmsmac and activates/installs wl which is garbage.

    If you have read this entire thread, you'll see that we've tried everything and every version of brcmsmac and, in this case, for some reason, it doesn't work really well. We do, however, appreciate your help. It is always helpful to hear from someone who owns one.

    Re: Broadcom BCM4313

    Sorry for the silence; I've been really busy recently. Your help has been amazing.

    The good news is that this seems to be working a bit better - it lasts about 20 minutes before shutting down. There's a lot of stuff in the blacklist file and something was interfering with it, so it's all hashed out at the moment apart from one entry, but something is clearly interfering still; perhaps you have a suggestion as to what it could be?

    Code:
    blacklist bcm43xx
    # blacklist b43
    # blacklist b43legacy
    # blacklist bcma
    # blacklist ndiswrapper
    # blacklist brcm80211
    # blacklist brcmsmac
    Thanks again for your help, and Varun's. I wouldn't have been able to make any progress at all otherwise.

    With Dr. Chili being on thread, you don't need me anyway, but I think it would be interesting to see a fresh 'wireless_script' report of your current setup.
