Thread: Wireless adapters can't load firmware on boot (both b43 and ath9k)

    Default Wireless adapters can't load firmware on boot (both b43 and ath9k)

    Hi,

    it's a cross post from SUSE Studio forum, as I have no access to the mail list

    Running openSUSE 13.1 32bit LiveCD built by SUSE Studio on my laptop that has two wireless adapters: b43-based and usb ath9k-based. Both are supported and correct firmware is placed where it should be. After boot I get errors that firmware can't be loaded:

    Code:
    [    3.646966] b43-phy0: Broadcom 4318 WLAN found (core revision 9)

    [    4.472826] usb 1-6: ath9k_htc: USB layer deinitialized
    If I unplug USB ath9k-based adapter and plug it again - it initializes fine and firmware is found. I can't unplug b43-based adapter to test because it is built-in, but rmmod b43 causes firmware to load, but kernel crash happens (there is bug filed for this - 810984). So firmware for both adapters is only available after some time after boot

    Is there a way to fix this so after boot I get both adapters initialized correctly?

    Thanks

    I use b43
    And the firmware I have works fine

    I place my firmware, a folder, b43
    In /lib/firmware

    Then run
    Code:
    su -
    modprobe -rv b43
    Code:
    modprobe -v b43

    Tested 3.12 kernel using SUSE Studio Live CD - same issue
    Looks like SUSE Studio or Kiwi issue?

    For legal reasons, firmware for b43 *cannot* be distributed under any
    circumstances!!! It is not a bug, but a dispute with the Broadcom lawyers that
    we lose every time.

    The ath9k firmware is located in the kernel-firmware package. Is that built into
    your SUSE Studio build?

    Firmware files included in build. And I have issue only loading firmware during boot. If I plug device after system has booted - firmware loads fine

    Hi,
    I'm sorry to bump this topic however I'm still affected by this issue

    Is there a way to make /lib/firmware appear before usb is initialized on LiveCD build by Kiwi (SUSE Studio)?

    Thanks

    Hi,
    I have the same problem. After start I always have to use "sudo /usr/sbin/install_bcm43xx_firmware" .
    Is there any way to do it automatically.

    Thanks

    You can try and put that command into /etc/init.d/after.local
    So far modprobe -r and modprobe work for b43 and ipw2200 devices
    But that does not work for ath9k. For some reason device does not show up after module reload. So need physically unplug/plug
