    Dell wireless card 1490

    After upgrading to Ubuntu 14.05 my Dell wireless card 1490 doesn't work anymore. I know this topic has been handled before, but none of the solutions offered there worked. I must say that up till now (Ubuntu 12.04, Ubuntu 13.10) it always worked perfectly, no problem. One of the solutions previously offered was, ironically, upgrading to 14.04! I have a Dell Latitude D531. Thanks for any help.

    In those previous threads, we always needed:
    Code:
    lspci -nn | grep 0280

    The result of lspci -nn | grep 0280

    is:
    0b:00.0 Network controller [0280]: Broadcom Corporation BCM4311 802.11a/b/g [14e4:4312] (rev 01)

    But then, according to the link you mention, which was one of the discussions I consulted, I proceeded to install linux-firmware-nonfree and was told that it was already installed.

    I got it working by installing ndiswrapper and then using the Dell driver for Windows. But I find that disappointing: to be forced to use a Windows thingy while it should work purely under Linux. It worked perfectly before under Ubuntu 12.04 and 13.10, without a Windows driver, so it should work again now. Only, however I tried, I couldn't find the method again I used under 12.04 to get it working. I only remember that it was a Ubuntu package from Broadcom's website. Apparently it's gone.

    To be able to use the Windows driver with ndiswrapper I had to blacklist bcm43xx in /etc/modprobe.d

    I would rather have used another, pure Linux method, but as they say: if it works, don't touch it, and it works now, so I guess I'm stuck with it.

    Thanks!

    Not at all. We can fix it easily and quickly if you're ready.
    I had to blacklist bcm43xx in /etc/modprobe.d
    There is no module bcm43xx since a looonnnngggg time ago.
    Code:
    chili@T410:~$ modinfo bcm43xx
    modinfo: ERROR: Module bcm43xx not found.

    Re: Dell wireless card 1490

    First, verify that you have the correct firmware:
    Code:
    sudo dpkg -s linux-firmware-nonfree | head -n5
    If it isnt installed, get it:
    Code:
    sudo apt-get install linux-firmware-nonfree
    Now remove the usually conflicting package:
    Code:
    sudo apt-get purge bcmwl-kernel-source  <--this is the step that many miss
    And the same for ndiswrapper:
    Code:
    sudo apt-get purge ndiswrapper*
    Check your blacklists:
    Code:
    gksudo gedit /etc/modprobe.d/blacklist.conf
    If b43 or ssb is blacklisted, remove the line(s). Proofread carefully, save and close gedit.

    Check what modules are forced to be loaded:
    Code:
    gksudo gedit /etc/modules
    If wl or ndiswrapper is listed, remove them. Proofread carefully, save and close gedit.

    Reboot. How is your wireless working?

    Perfect! Thanks a lot! Could it be that "purge bcmwl-kernel" made all the difference?
