    Ubuntu 10.04 not detecting wired networks

    Hi,

    My ubuntu 10.04 install can only detect wireless networks and not wired connections. I have a dual boot machine and there is no problem detecting wired networks on the windows boot but not the ubuntu version. Is there any suggestions on how to fix this?

    I thought it might help to post the output from '
    iconfig -a'

    Re: Ubuntu 10.04 not detecting wired networks

    Given that 10.04 will stop being supported in April this year; just a few weeks from now; I wouldn't bother. I would make sure I had good backups and do a clean install of 12.04.
    Not an upgrade as if there are problems with your network settings they may be copied into the upgrade.

    However, If you don't want to upgrade then open a terminal and with a LAN cable plugged in give us the output of the following terminal commands

    ----------------------------------------------------------------------------------------------------
    sudo lshw -C network; ifconfig; route -n; cat /etc/network/interfaces
    ----------------------------------------------------------------------------------------------------

    Enter password when requested. You may need to unplug the LAN cable to get Wifi back so you can post the results

    The results of

    Re: Ubuntu 10.04 not detecting wired networks

    The problem is here
    Code:
    *-network UNCLAIMED     
           description: Ethernet controller
           product: Intel Corporation
           vendor: Intel Corporation

           width: 32 bits
           clock: 33MHz

    UNCLAIMED means there is no driver claiming it

    Try
    Code:
    sudo apt-get install linux-backports-modules-lucid
    Enter password when requested and reboot to test.

    Re: Ubuntu 10.04 not detecting wired networks

    Thanks for finding the root of the problem.
    However the package linux-backports-modules-lucid wasn't found. Are there any other options I could try?

    Re: Ubuntu 10.04 not detecting wired networks

    Have tried
    Code:
    sudo apt-get install linux-backports-modules-wireless-lucid-generic
    and still get the * - network UNCLAIMED response.

    In some of the other post I saw that the output from
    Code:
    lspci
    might help. This is :

    I don't fancy upgrading the operating system as I have several specialized programs, so would like to fix this if possible.

    Cheers.

    Re: Ubuntu 10.04 not detecting wired networks

    Go here.

    http://www.intel.com/support/network/sb/CS-012904.htm

    Instructions for identifying your adapter on linux and then you can search intel for the proper drivers. They do support linux. Your problem is intel always packages their drivers into the Linux Kernel. The newer the kernel the newer/more drivers you have. 10.04 is obviously using a very old kernel, therefore it has old outdated drivers.

    Good luck!

    P.S.

    if you want to keep 10.04, look into updating your kernel to something more recent.
