    Inspiron 15R 5520 failure to detect wireless device

    Hallo,

    I have a problem with the wireless device on a Dell Inspiron 15R 5520 using ubuntu 12.04 (32bit). It seems that the wireless device is not detected at all by Ubuntu. It is neither listed in the dropdown menue for network settings, nor can I choose it in the menue for system settings, where only cable and proxy are listed. The wireless works fine under windows 7, though. I assumed that all hardware should be recognized by Ubuntu since the computer is listed as certified in Ubuntu's hardware list, although with a pre-installed Ubuntu: http://www.ubuntu.com/certification/.../201201-10377/

    Here are a few results from commands that have been suggested for the problem in an earlier thread (http://ubuntuforums.org/showthread.php?t=2010710):

    Looks like you have an unsupported device:

    Network controller [0280]: Broadcom Corporation Device [14e4:4365]

    Perhaps a kernel update will fix it, not really sure.

    Can you plug in with a cable, do an update then check in 'Additional Drivers'?

    Hi Bucky Ball,

    Thanks for you reply. By update you mean a kernel update with this command?

    Code:
    sudo apt-get install --reinstall linux-image-$(uname -r)
    As to now, there is only a proprietory graphics driver listed for "additional drivers"

    Thanks!

    Re: Inspiron 15R 5520 failure to detect wireless device

    No. I mean a simple update. To upgrade packages as well (if available and you should always run the update command first):

    Code:
    sudo apt-get update
    sudo apt-get upgrade
    Stick with the kernel you have and you know is working for now. You don't want to confuse the issue by installing a kernel which may have other issues and break the system in some other way (or cause a totally different wireless problem). And maybe you could also post back the result of:

    Code:
    sudo lshw -C network
    Thanks.

    PS: In Software Centre, do you have b43-fwcutter and b43-firmware-installer (that last one could be wrong but do a search for b43 and you'll find it)?

    Hi, I to believe as well at the moment your device is not supported by ubuntu the only option you have is to use ndiswrapper, I have not helped anyone with ndiswrapper before so it is really not my area of expertise but here is a link.
    https://help.ubuntu.com/community/Wi...er/Ndiswrapper
    Thanks

    Hi, please see post 13, that is the only chance of getting your device to work in ubuntu at this time.

    Re: Inspiron 15R 5520 failure to detect wireless device

    So far there are no reports that ndiswrapper really functions. Since I don't want to take the risk of smashing my system right now, I am not going to try it. Please see these two links with reports on unsuccessfull installations with ndiswrapper:
    https://bugs.launchpad.net/ubuntu/+s...51/comments/69
    http://forum.ubuntu-fr.org/viewtopic.php?id=966811
    ... Its hard to tell however whether these attempts have been carried out properly without more information.

    Hi, that is up to you but if you install ndiswrapper and it does not work it will not break your system, we just give you the commands to remove it, but I am not the person to help you with installing ndiswrapper since you are scared of it to begin with and it is not experienced with it.
    Thanks
