Thread: WLAN module doesn't load automatically at boot - 11.4 KDE x86_64

  1. #1

    Default WLAN module doesn't load automatically at boot - 11.4 KDE x86_64

    Using tips provided in the "Sticky" posts, I have identified my wireless device -- BCM4322 -- and installed the necessary firmware and drivers. The device appears in Network Manager until system reboot, at which time the "ssd" driver module is loaded instead. After each boot I must execute the following commands to remove ssd and load the Broadcom driver:

    rmmod ssb
    modprobe lib80211
    modprobe wl

    The Broadcom README file provides directions to load the correct module automatically, but the commands appear to be incompatible with openSUSE 11.4. I'm happy to provide additional detail if needed. Please be specific.

    Note: ssb, not ssd.

    Add "blacklist ssb" to the bottom of /etc/modprobe.d/50-blacklist.conf.

    Run the command 'sudo /sbin/depmod -a". Now it should work. The commands have
    not changed. You did something wrong.

    Thank you for your effort to assist. I have confirmed that "blacklist ssb" appears in /etc/modprobe.d/50-blacklist.conf and in /etc/modprobe.d/blacklist.conf (as documented in the README file obtained from Broadcom's website).

    Nonetheless, loading of the "ssb" module persists at system boot, and so I must continue to run 'rmmod ssb' and 'modprobe wl' to unload "ssb" and load "wl" instead. (Through experimentation I have determined that the 'modprobe lib80211' command suggested by Broadcom is unneeded.)

    The Broadcom documentation says, "Sometimes blacklisting ssb may not be enough to prevent it from loading and it loads anyway." (Yes.) And here's the solution they suggest:

    Back up the current boot ramfs and generate a new one.
    # cp /boot/initrd.img-`uname -r` somewheresafe
    # update-initramfs -u
    # reboot

    As you probably know, the 'update-initramfs -u' command is unrecognized by openSUSE 11.4. I'm hopeful you or someone else can suggest something comparable if it is a matter of simply "clearing the cache", so to speak.

    If ssb were in the initial ramdisk, then you would need that command; however,
    it never is.

    The 'modprobe lib80211' command is needed if you use Broadcom's build procedure
    as they are not smart enough to include the crucial 'depmod -a' step after
    copying the driver to the /lib/modules tree.

    Please post the output from 'sudo /sbin/lspci -nn'. You may have a b44 wired
    device on your machine. If so, it needs ssb and the loading procedure gets harder.

    Nothing there jumps out at me. However, your comment set me to thinking.

    My primary network device is Mobile Broadband, which I've been using for about four years. Recently I traded my Novatel CDMA device for a Franklin dual band 3G/4G. Linux doesn't support the 4G communications chip at this time. Nonetheless YaST showed the presence of a Beceem Communications BCSM250 Mobile WiMAX device as well as the U600 EVDO Modem.

    Following installation of the Broadcom WLAN drivers I have discovered that the WiMAX device is no longer listed by YaST. However, the EVDO modem is still there and continues to function normally. Thinking there might be a connection, I have tried booting the system without USB Mobile Broadband installed. No difference. WLAN and the EVDO modem coexist peacefully, and Network Manager handles them side by side.

    Clearly, you do not have a b44 or a Broadcom gigabit network controller that
    need ssb. My only suggestion is that you add the lines '/sbin/modprobe -r ssb'
    etc. to /etc/init.d/after.local. That way the correct modules will be loaded.

    I have no idea what is making the kernel sidestep the blacklisting of ssb. Note
    that when 11.5 comes out, b43 will be able to handle your BCM4322 and you will
    only need to install the firmware with the install_bcm43xx_firmware script.

    It's working now! Thank you very much.

    While I'd be interested to know whether the problem would recur with a clean install, it just doesn't seem worthwhile to rerun setup to satisfy my curiosity. Thanks again!

    I don't think this is an installation problem, but some hardware quirk that
    triggers a software condition, or perhaps even a bug. I have one Broadcom device
    that has an Ethernet core in the chip that is not connected to the outside and
    is essentially dead. Its presence, however, caused b44 to load. We fixed that
    case, but something similar must be happening with your box.

    I have the same problem. I am unable to know what to do. The contents of /etc/modprobe.d/50-broadcom-wl-blacklist.conf file is:

    Code:
    # modules blacklisted for broadcom-wl
    blacklist bcm43xx
    blacklist ssb
    blacklist b43
    blacklist ndiswrapper
    blacklist brcm80211
    Still ssb module is loaded. And where do I put for the wl module to get loaded.

    Please help.
