    Dell inspiron 1501 network problems

    Hey I am newbie to ubuntu 12.04 Lts and I installed it on my dell inspiron 1501 laptop. I installed it with dual boot with windows vista. I am having problems with the network. The wired and the wireless does not work. Can anyone help me out. I have tried some of the post but most threads i found want you to hook up the wired connection but like I said it does not work. Thanks.

    Please give us more information about your ethernet and wireless devices. Please open a terminal and run and post:

    Please get a temporary wired ethernet connection. We are going to get it going easily in one step:
    Code:
    sudo modprobe b44
    sudo apt-get remove --purge bcmwl-kernel-source
    sudo apt-get install linux-firmware-nonfree
    Detach the ethernet, reboot and everything should now be working.

    When I entered the first line of the code the wired connection established but toward the end it says E:unable to locate package. Did something go wrong.

    ok tried that and still says unable to locate it. I did the additional driver update and it found the sta driver and it said it needed to reboot and now it is stuck on a bunch of writting and it will not boot into ubuntu. Well have to go to bed work comes early I will get back tomorrow.

    You do not want the STA driver! That's what is causing all these problems in the first place!! Now you've reinstalled it!

    See you tomorrow...

    I am posting this so that, perhaps, other newbies and searchers will see and heed it.

    The 'Additional Drivers' tool cheerfully offers the wrong driver for a few Broadcom wireless cards, including your 4311. Then you get in more difficulty than just, 'my wireless won't work.' You get:
    it said it needed to reboot and now it is stuck on a bunch of writting and it will not boot into ubuntu.
    So, newbies, search this forum for SOLVED and your pci.id, something like 14e4:4311. Follow the process in the solved thread and don't take Additional Drivers' suggestion to wreck your system.

    End rant.

    So, Mike, start by telling me what Ubuntu version you have:
    Code:
    lsb_release -a
    uname -r
    Next, hook up the ethernet and do:
    Code:
    sudo modprobe b44
    sudo apt-get remove -purge bcmwl-kernel-source
    You need firmware for your 4311 wireless and the best method to install it depends on your version.
