    [Solved] NetworkManager displays eth0 : Unmanaged & NIC [Not updated yet]

    Hi Guys,

    I have an onboard RTL 8139 NIC with Wake on LAN Disabled,
    with Dual Boot XP on a Intel 845 Chipset motherboard.

    Earlier when I booted into KUbuntu the NIC was never detected
    and I noticied that Manage Network Connections, did not have a Default eth0
    connection created, so I added a new connection and named it Auto eth0
    and I modified interfaces and resolve.conf files     and now the state of the issue is this :

    On Hovering over the Network Manager Widget displays eth0 : Unmanaged
    Clicking on it shows Networking Interface[Not updated yet] - IP Address : dum.my.ip.addr
    Moreover the option "System Connection" below "Connect Automatically"
    is disabled >

    I have only one NIC and am assigning a Static IP

    I have tried iamme@incognito:~$ /etc/init.d/networking restart
    and when I try to open sudo /etc/init.d/NetworkManager nothing happens

    I had Ubuntu earlier and it had no problem
    detecting an connecting to the interface, so I believe this
    could not be a driver issue.

    Here are my modified files
    Code:
    iamme@incognito:~$ cat /etc/resolv.conf

iamme@incognito:~$
    Is there anything else I could try to resolve this, besides either waiting for
    Karmic Koala to release or switch back to Ubuntu.
    Though that would be a workaround and not an resolution.

    I really like the KDE desktop and would love to have this resolved.

    Thanks for all the help you provide, in advance.

    The default network manger in the current versions of Kubuntu is, as said by many, not desirable. I'm assuming that you do have a working internet connection with this PC, or are you on another? What others here are/will/would advise, is to install wicd as your network manager. It does a much better job over the default.

      Yes I have noticed this, but I am not sure from where could I download the package, and how to install it, could you let me know?

      Yes the internet connection is working fine on Win XP, the other OS
      loaded on my system. ( I am accessing the net and posting this reply
      using it right now ) and I had also mentioned that GNOME on Ubuntu had no issues detecting and connecting to the interface.

        OK I am googling to find more about WICD, and to see how to install in on Linux,
        I'll try it and post results.

        Thanks

          There is no "auto eth0" in your interfaces file.

          Suggest you do this, it is the quickest, easiest, and most reliable solution.

            [Solved] NetworkManager displays eth0 : Unmanaged & Networking Interface

            Hey people,

            Guess what, I am posting this from Kubuntu

            Here is what I did,

            - Downloaded the deb package for WICD from http://packages.ubuntu.com/jaunty/net/wicd
            - Also downloaded the following dependency packages from the Ubuntu package repo
            python - 2.5.2-2
            python-glade2 - 2.12.1-6
            python-gtk2 - 2.12.1-6
            python-support - 0.8.6

            - Un-installed NetworkManager
            - Installed the deb packages, and that is it; rebooted the system.
            - Reconfigured the network and just like that I am online
            Even though I am posting it now, I have must confess I have been online for the past 3 days now.

            I was hoping we could try tweaking NetworkManager and resolve this rather
            than installing WICD. Now this makes me wonder, WICD is open souce
            so why not include it as an alternate Network handler in Karmic Koala.

            Thank you Snowhog and Detonate for your suggestions.
            I assume that guys who are not sound with the command line may find
            http://kubuntuforums.net/forums/inde...opic=3100052.0 a bit confusing.

            But thats my view and nothing else.

            Thank you everyone.

            iamme - still and will always be - hehe
