    Smile Jaunty Broadcom (BCM4328) Wireless Problem

    Hi all,

    appear to be having a problem with my laptop's wireless now I have just installed 9.04. 8.10 also had a problem, but only showed itself when connective to WPA2 networks. 8.04 on the other hand worked flawlessly. In this version though, the problem appears to have gotten worse - now the network manager can't see my wireless card at all!

    So...

    The machine is an HP tx1340ea, with a Broadcom BCM4328 network controller.

    Its a bit weird, I was actually posting a problem report but then I was going through the steps in various troubleshooting threads to try and give some useful information and it started working!

    The sequence of events since I installed it fresh this time round was:
    I uninstalled the Broadcom STA wireless driver, restarted, used the switch on the front to turn the wireless card off, restarted, used the same switch to turn it back on, restarted, reinstalled the Broadcom STA wireless driver, restarted. Hey-presto! It appears to be working.

    It even seems to still work after multiple normal reboots!

    Hope this is helpful to someone, if anyone has a logical explanation for this I would also love to hear it!

    I have the same issue and what you did fixed it for me as well!

    In windows that would have been the first thing I tried... I don't tend to think that way when using Linux...

    Thanks a ton dude, I just had the same issue and this worked. Kind of a silly fix.. I'd like to know the logic behind this as well!

    I submitted a bug for this issue, https://bugs.launchpad.net/ubuntu/+bug/365857 with the hope that a fix that doesn't require rebooting will be found. I may try out the rebooting technique but I'm not sure that I'm properly uninstalling the driver since I'm using the kubuntu hardware driver manager jockey.

    From this thread, http://ubuntuforums.org/showthread.php?t=880218 I tried the fix that someone recommended of:

    sudo rmmmod ssb
    sudo modprobe wl

    And bam, the wireless device started showing up in the network management plasmoid and I'm able to connect and use wireless. I don't know how to ensure that this happens after rebooting though.

    To clarify, this lets wifi work for me but I'm not sure if this is using the "broadcom sta wireless driver" listed in the hardware driver manager, it may be using the default kernel drivers for broadcom chips so it may not be equivalent at all to the originally suggested fix in this thread.
