    Another Broadcom issue

    Hi there,

    I have been at this for over 10 hours now, trying to get wireless to work, I think I have gone thru all the forum solutions and nothing is working...

    here is my card specks

    Network controller [0280]: Broadcom Corporation BCM4321 802.11a/b/g/n [14e4:4328] (rev 05)

    I have the wireless tab showing in network, but no networks are showing

    I am using the latest LTS 12.4 and I am comletely at a lost so I am hoping someone with a bit of experience can help me out... I am a total noob, just installed today. The sad thing is that it all went perfectly, apart from the wireless setup... it's almost making me quit infrustration and try another distro but I will give it one more try.

    From the amount of support requests out there concerning Broadcom cards, maybe there is a bug somewhere?

    Anyway TIA for any help you can give!

    Support may be limited with b43 so try wl (make sure you are fully updated)

    do

    Code:
    sudo apt-get install bcmwl-kernel-source
    then reboot

    Hello Carl, thank you for your response, done this before didn't work, but I will try it again the thing is that I always get a fatal error when installing the bcmwl:

    Re: Another Broadcom issue

    The default version of the bcmwl-kernel-source seems to have gotten some bug recently that causes it to fail to compile. My usual reference in this case has been to try an older version directly downloaded from broadcom's site > patch it with some patches I know and understand > compile > install.

    However, one user recently posted a link to a newer version that installed smoothly on his system (with kernel 3.8.0-29, 64 bit). So I would suggest to try the same package before trying anything else -
    https://launchpad.net/ubuntu/+source...+build/4761504

    Download the .deb package from above link, and double-click to install (while being connected to internet via cable, so that dependencies can be installed if there are any).

    Please let us all know how it goes. Thanks !

    Nope no change, it seemed to install ok, but still not detecting any wireless networks! From time to time I am also getting this error:

    Crash Report
    Sorry a problem occurred while installing software.

    Package: bcmwl-kernel-source

    lots of details but I guess the main one is:

    bcmwl kernel module failed to build
    Thanks for the help guys I really appreciate it. apart from the wireless issue, everything else is working perfectly so far.

    Re: Another Broadcom issue

    Guys a breakthrough!

    In a last act of desperation I tried the "connect to hidden wireless network" option and added the name of my wireless network and password... and damn me it worked! After it connected it started picking up available wireless networks as well! So it is almost like this bumped it into action. It may have been the second boot after Varunendra's fix that could have done it, not sure... but anyway it is working now. thanks!

    Re: Another Broadcom issue

    Great ! And thanks for the feedback !

    I believe saving the network SSID and security key to NM helps in this case, so the key to success should be that one. But "failed to build" errors mean either there are still remnants of previous failed attempts with bcmwl-kernel-source, or even the last one I porposed also failed.

    To fix that, you may try to completely purge the package(s) and retry with the one I linked to in my previous post -
    Code:
    sudo apt-get purge bcmwl-kernel-source
    sudo apt-get clean
    sudo apt-get autoremove
    Then reinstall the downloaded .deb package for latest bcmwl module.

    Obviously, none of above is necessary if everything is working now.

    Don't reinstall bcmwl
    Because we just need to establish if you are using b43 firmware that I sent you privately
