    Network Manager - Wired Network - device not managed?

    Network Manager shows this error when I click on it, but it seems my wired network connection works? The icon on the top bar also looks like there is a connection problem??

    Ran into a similar problem with a broadcom 43xx card.

    Run lshw -C network... what kind of card are you using?

    make /etc/NetworkManager/nm-system-settings.conf to look like:
    Code:
    [main]
    plugins=ifupdown,keyfile
    
    [ifupdown]
    managed=false

    It's an ethernet port off an Intel Pentium 4 motherboard, so it's not really a card. I would assume it uses the Intel chipset. Kind of disappointing since it's worked flawlessly in several other versions of Ubuntu.

    Can you tell me the exact command to run you mention above? The lshw one? I get lost after the three dots after the word "network".

    Thank you!

    Re: Network Manager - Wired Network - device not managed?

    hi, i am having this trouble also. never noticed it before because i always used just the wireless, which works fine.

    and to Zika: my /etc/NetworkManager/nm-system-settings.conf looks exactly the same as what you posted.

    here is what i get when i run the command
    shalwes@greyfox:~$ sudo lshw -C network

    i realize the last one says disabled and it's supposedly a physical port (although i only have 1 physical port, just clarifying) but i dont know how to enable it or if thats even my problem.

    also, is this just a problem with jaunty? i assume so, but o well

    try changing managed=false to managed=true if You want NM to manage Your wired. In JJ things settled and I, for now, on all 4 machines, do not have anything else but NM ...

    Re: Network Manager - Wired Network - device not managed?

    Hi, I had the same problem with Jaunty. Wireless was working through ndiswrapper (with b43 couldn't connect to WPA encrypted networks). Then wired network suddenly didn't work. I noticed that the problem was that b44 module wasn't loaded. sudo modprobe b44 fixed the wired problem. I have a Dell Vostro 1700, with Broadcom network cards.

    I had the same problem with the wired connection after upgrading from 8.10 to 9.04 RC.

    Changing [ifupdown] managed=false to true in /etc/NetworkManager/nm-system-settings.conf resolved the issue.
