    Can't connect to Wireless with Broadcom BCM4313

    I've looked through quite a few topics on this subject, but haven't exactly been able to fix my problem at all. The drivers it gives me to download from Additional Drivers certainly doesn't work.

    Yesterday, though, it seemed to magically work for a while, actually. Then I had to close my laptop and go somewhere else. It seems the magic went away and I can't connect again.

    I tried a fresh install and it still doesn't seem to work... Tried quite a few other solutions that I read about, but they don't seem to work.

    Using 11.10 Ubuntu.

    The following commands (one at a time should take care of you)

    Code:
    sudo apt-get install --reinstall bcmwl-kernel-source broadcom-sta-common broadcom-sta-source
    echo "blacklist brcmsmac" | sudo tee -a /etc/modprobe.d/blacklist.conf
    echo "blacklist bcma" | sudo tee -a /etc/modprobe.d/blacklist.conf
    The first makes sure that the sta driver is in place, the second and third blacklist the two drivers brcmsmac and bcma which clash with the correct sta driver. Copy/paste or make sure your typing is correct!

    Sorry, that didn't work. Maybe I'll try it with a fresh install.

    (yes, this is a different account, I couldn't remember the password for this one earlier, so I just made a different account... Remembered it now!)

    I wouldn't bother with a fresh install just yet. Keep digging on this problem. If it's not working now, it is 11.10 and your card (you have already re-installed and it achieved nothing).

    o_o I downloaded wicd network manager and I can connect through that, but not through the default network manager.

    Don't understand. Thanks, guys.

    Forgot to mention that a reboot would be necessary to blacklist the competing files, perhaps you did that when you installed wicd??
