    Re: User new to Ubuntu with Networking Problems

    As I expected, plugging the same cable from the same port into my MBP works perfectly well.

    That is indeed a reasonably recent kernel, and good for 12.04.

    Either solution seems satisfactory.

    I recommend one last test before going the hardware route - try a different LiveCD or LiveUSB (like 11.10), and see if you get the same result.

    Yeah I've tried with several different Live CDs, same result. I guess I'll buy an ethernet card.

    Thanks a bunch for your help.

    Anyone know off the top of their heads a good, relatively inexpensive Gigabit PCI card that plays nice with 12.04?

    My situation is close...
    I upgraded a working dual boot (Linux Mint 12 Debian Edition 64-bit primary plus WinXP until I can be sure I don't need anything that won't run under Wine) to a new ASRock N68C-GS FX mobo which has onboard RTL8211Cl 10/100/1000 Mbps ethernet.

    Windows XP just works after I installed the nVidia drivers (and re-validated my Windows licence).

    Linux Mint initialises the card using the forcedeth driver but never gets an address via DHCP. dmesg reported "link not ready" and the lights are odd. I think that the card never negotiates an ethernet connection with the router at the other end- "2-wire" brand, model 2701HGV-W supporting 10/100 wired LAN ports. Naturally, the router is running *nix but with a GUI which stops you doing anything useful like disabling auto negotiation on the ethernet ports.

    The GUI shutdown process stops before turning off the power- I don't get a melted screen, but still no hard stop. Interestingly, "shutdown -h now" in a terminal does turn off the power correctly.

    I tried using ethtool to force 100 Mbps, but saw no improvement. ethtool runs runs only when we are a multiuser runlevel, and probably the router has finished wanting to negotiate by then.

    I tried Live CDs for Africa- Ubuntu 10.04 and 12.04 32- and 64-bit, 'raw' Debian, Puppy. All the same as Linux Mint.

    I ended up sticking a very old ne2000 clone in and of course, it sprang to life immediately- but with a cost in expected performance. So I would like to solve this, if I can.

    Any more ideas?

    i have the exact same problem. i have the N68C-GS FX asrock mb and it was working well. then i changed my cpu to fx 6300 amd with 2 ddr3 2gb ram and since then i don t have wired network. i have triple boot with windows 7 and windows 8 and the work fine. i tried live cd s from 9.10 untill 12.10 with no luck. i tried disabling and re enabling my lan from bios but still no luck. tried a clean install twice and nothing. tried both static and dhcp. ubuntu recognise my card normally and i don t know what to do. it is very frustrating. any ideas?

    Re: User new to Ubuntu with Networking Problems

    after contacting with as rock the guys there gave me the following answer.

    Thank you for contacting ASRock.


    We did various test on BIOS but cannot improve this.

    After doing some research, we found changing some driver(forcedeth) setting would help on this.

    It seems that there's something wrong at LAN driver for NVIDIA chipset (forcedeth) working with AM3+ CPU.

    And due to the non-working driver, you might also see the system not really powering off when shut down or freeze when restart system.



    Here's the steps to temporarily enable the network:

    step 1. Enter Ubuntu recovery mode:

    a. Power on system and press "Shift" during boot up for GRUB memu.

    b. Choose "Advanced options for Ubuntu" > Ubuntu, [kernal version] (recovery mode)

    step 2. Choose "root" and key in below command:

    # rmmod forcedeth

    # modprobe forcedeth msi=0 msix=0

    # exit

    step 3. Choose "resume" to resume normal boot

    Now the network should be ok till next boot with AM3+ CPU.



    If the trick works on your system, please modify below file to automatically run the script when boot up:

    step 1. Add the line "exec rmmod forcedeth" at next line of "script" in the file /etc/init/module-init-tools.conf

    Add the line "modprobe forcedeth msi=0 msix=0" to /etc/rc.local

    step 2. Restart system for check

    For detailed steps, please have attached file for reference.

    tried both things and they work great. it even reboots and shuts down normally. so if anyone has this try the above solution.

    Re: User new to Ubuntu with Networking Problems

    Package changed in 13.04
    step 1. Add the line "exec rmmod forcedeth" at next line of "script" in the file /etc/init/kmod.conf

    Same bug here, solved with the rmmod/modprobe workaround.

    Thumbs up Re: User new to Ubuntu with Networking Problems

    Same problem here - 3 months hunting for a solution! Finally solved with forcedeth module parameters.

    Kernel: 3.11.0-12-generic
    AMD Proc X8 FX8100

    lspci -nnk | grep -iA2 net
    Code:
    00:07.0 Bridge [0680]: NVIDIA Corporation MCP61 Ethernet [10de:03ef] (rev a2)
    	Subsystem: ASRock Incorporation 939NF6G-VSTA Board [1849:03ef]
    	Kernel driver in use: forcedeth
    Thank you!
