    Default Wireless network problem on Macbook Air, Broadcom Corporation BCM43224

    Greetings

    Thanks in advance for your help... I am struggling with a fresh new OpenSuse 13.1 installation on a 2010 Macbook Air. lspci lists the wlan as a Broadcom Corporation BCM43224.

    Lsmod shows : bcma 46699 2 brcmsmac,b43

    Under network settings, the device appears as wlp1s0

    When I run ifup on the device, ifconfig hangs, and I have to reboot. If I set it to come up on boot, it freezes during boot-up.

    The macbook air is fully reliant on wireless networking, so this is a bit of a major problem!!

    I have googled this extensively, and have got nowhere.... It is really critical that I have the laptop operational in time for Monday morning's work!! ARGH! Help, please? Can anyone talk me through some suggestions to try??

    Yours again with thanks,

    Jamie

    You will probably get more responses from more knowledgeable people by posting in the Wireless sub-forum. There are several guides there.

    You need to install Broadcom drivers. They are not in the base installation because of licensing issues.

    On a machine with internet access, go to http://packman.links2linux.org/packa...dcom-wl/474269
    Under Releases, click on the one corresponding to your version and kernel, such as
    6.30.223.141_k3.11.10_7-2.7 openSUSE 13.1 x86_64

    In the new window, under Downloads, click on the rpm file for the macbook air's type of kernel - default or desktop. Save that file to some medium that you can read with the macbook air.

    On the macbook air, put the broadcom rpm in a folder in your home directory. In YaST, create a new repository that is a Local Directory, Plain RPM directory, pointing to where you put the broadcom file. Use YaST to install the broadcom driver.

    I prefer Network Manager over ifup, but I'm a GUI type. NM worked to connect my broadcom wireless card to our network.
    Hope this helps.

    Just to add, only downloading/installing the kernel module package (kmp) is _not_ sufficient.
    You need the one named "broadcom-wl" as well:
    http://packman.links2linux.org/packa...dcom-wl/474270

    OTOH, the Broadcom drivers should not really be necessary.
    The kernel does contain a working driver for that card, maybe you would have to install additional firmware though.
    But the broadcom-wl driver should work in any case.

    FWIW: My MBA 4.1 running Suse 13.1 (kernel-desktop 3.11.10) with the same broadcom chipset and bcma (brcmsmac,b43) driver works quite well.

    I did not install any additional broadcom drivers, the in kernel ones are working fine for me. Nor did I install the broadcom-wl package.

    When ifconfig hangs, does the entire system hang? Can you get out to a virtual terminal to check dmesg, etc. to see if there is any additional information? Does /var/log/messages have anything interesting after a fresh boot before attempting to bring the interface up?

    If you boot to a 13.1 live CD does wireless work?

    Are you booting with any kernel arguments which might be influencing things? (cat /proc/cmdline to see)

    As a possible workaround for your Monday deadline, could you obtain a USB wi-fi adapter to use temporarily, or an Apple USB Network adapter to get you through?

    Probably, my laptop needed the broadcom drivers installed separately because wireless is through a PCMCIA card. The card was not inserted during the openSUSE 13.1 installation. I expect that with built-in wireless, the hardware is detected during installation, and the right drivers included.

    As a test, I removed broadcom-wl and broadcom-wl-kmp-default, inserted the PCMCIA card, and rebooted. /var/log/messages contained this

For an off-line installation, go to http://en.opensuse.org/HCL/Network_Adapters_(Wireless)/Broadcom_BCM43xx and follow the instructions in the "Installing firmware from RPM packages" section.
    Neither Network Manager nor YaST detected the card. The suggested
    Code:
    sudo /usr/sbin/install_bcm43xx_firmware
    returned "command not found".
    I plugged in the network cable, installed broadcom-wl-kmp-default and rebooted. Selecting broadcom-wl-kmp-default for installation did not pull in broadcom-wl as a dependency. On rebooting, the card was still not detected - same /var/log/messages content. Finally I installed broadcom-wl, rebooted, and wireless works correctly.
    As wolfi correctly stated, both broadcom-wl and broadcom-wl-kmp-default(desktop) are required.

    Lesson learned is, have the card inserted during oS installation, and the right drivers will be included from the start.

    HAHAHA!!!! YES!!!! You know that total elation when, at last, it suddenly works? Haven't had that for a while, but certainly did, this weekend!

    Thank you so much for your very very kind responses to my issue with the Macbook Air. I'm delighted to say that this is being typed from it
    I can hardly believe that I was so dumb as not to check /var/log/messages when ifup hung... must have been stress or something. Duh...

    Anyway - thanks again for all the suggestions, which I worked through, and discovered that the problem was the lack of the two firmware files. Once I'd installed the linux-firmware package, we were AWAY!

    ....and it's not even Monday yet )

    Great! Glad you got it working.

    Some halcyon day in the future computers will just work, but until then fixing things is pretty much awesome. :}
