    Re: Solution to Broadcom 43xx Card Problem (12.10 - Quantal Quetzal)

    Hello,

    I am also having wifi problems. I am using Broadcom BCM4312. With Ubuntu 10, everything worked fine, but today I upgraded to Ubuntu 12 and wifi doesn't work.

    I'm trying my best to follow the advice in this thread, but I'm still an Ubuntu novice, so I'm not sure I'm doing things right. In particular, there are places where the instructions say to install from the "restricted repository", and I don't know how to do that because the Ubuntu Software Center never asks me where to install from.

    From what I've read, I believe I need the driver called "wl", which can be installed with the packages "bcmwl-kernel-source". The Ubuntu Software Center tells me that package is already installed. As long as it isn't blacklisted, wl should allow me to activate the "Broadcom STA wireless driver" through System Settings / Hardware / Additional Drivers. When I look through the blacklist file, I see no evidence that it is blacklisted. Nevertheless, when I try to activate Broadcom, I get an error saying "Sorry, installation of this driver failed". It refers to a log file, but I don't know how to interpret the log.

    Can anyone tell me what step to try next?

    The only way I got to solve the problem was to install kernel 3.7.0
    I proceeded this way :
    Code:
    mkdir kernel3.7.0 && cd kernel3.7.0
    
    wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.7-raring/linux-headers-3.7.0-030700_3.7.0-030700.201212102335_all.deb
    
    wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.7-raring/linux-headers-3.7.0-030700-generic_3.7.0-030700.201212102335_amd64.deb
    
    wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.7-raring/linux-image-3.7.0-030700-generic_3.7.0-030700.201212102335_amd64.deb
    
    wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.7-raring/linux-image-extra-3.7.0-030700-generic_3.7.0-030700.201212102335_amd64.deb
    
    sudo dpkg -i *.deb
    
    cd ..
    
    rm -r kernel3.7.0
    Note : this works only for a 64 bits computer.

    Re: Solution to Broadcom 43xx Card Problem (12.10 - Quantal Quetzal)

    Hi guys,

    I just installed Lubuntu 12.10 Quantal on an old Dell Inspiron e1505. I have a Broadcom wireless card; I've installed b43-fwcutter, dkms, bcmwl-kernel-source, and the STA Linuxx driver, and still have no possible way to connect wirelessly. Any suggestions, guys?

    Re: Solution to Broadcom 43xx Card Problem (12.10 - Quantal Quetzal)

    For me, the problem cropped up with BCM4313 after I installed the backport to support my Atheros R8161 LAN card.

    What happened was that it was loading the old module for lib80211 and failing to load the newer lib80211_crypt* and wl modules after that.

    I manually fixed it by rmmod the lib80211 module, and insmod the lib80211.ko from the backport directory, followed by the lib80211_crypt* modules from the same directory, and modprobe wl.

    Question is how can I set it to automatically load the lib80211 module from my backport directory at /lib/modules/3.5.0-22-generic/kernel/net/wireless?

    There's another existing /lib/modules/3.5.0-17-generic existing as well.

    Re: Solution to Broadcom 43xx Card Problem (12.10 - Quantal Quetzal)

    I have been having this problem as well. I have a BCM4312, and followed the instructions in the first post. It did not seem to work the first time, but it works if I run

    Code:
    sudo modprobe b43
    Of course, I have to do this every time I start up.

    I noticed that b43 was blacklisted in both the blacklist-bcm43.conf and blacklist-sta-common.conf files. I commented them out (I think--put a # in front of them), but to no avail. It does not seem to work without running the command each time I start up. Any thoughts?

    Re: Solution to Broadcom 43xx Card Problem (12.10 - Quantal Quetzal)

    The Broadcom 43xx problem has apparently resurfaced. After a kernel update about a week ago, Broadcom BCM4313 quit working in12.04 on an Acer Aspire One 722-0879 (AMD processor). There is a bug report #1110139 that reports these symptoms:

    The wifi card searches for a network without ever finding it even though it reports a connection. 2 most recent kernel updates do not fix the problem. My temporary solution is to connect a usb wifi card and disconnect the Broadcom reported connection as soon as the added card connects. This is cumbersome.

    I hope there is a fix soon.
