    Realtek RTL8111E linux network driver not working

    I am running a fresh install of Ubuntu 12.04 LTS on my desktop with a Gigabyte GA-Z68A-D3H-B3 motherboard, which (unfortunately) uses the Realtek RTL8111E LAN chip. It's a well documented issue that the network cuts in and out or runs very slowly on Linux—I'm experiencing this as well.

    I downloaded the official Realtek driver (r8168-8.035.00.tar.bz2) and successfully ran "sudo ./autorun.sh".

    If I run this script while my network is non-functional, it will fix it. However, inevitably, a couple minutes later, the network will cut out again until I re-run the script.

    I'm not sure exactly what's going on. Realtek did not respond to my support request, I have tried numerous online tutorials for older versions of the driver/kernel, and I attempted to make the switchmod script work. I didn't have success with any of them. (Note: Unlike this guy, my motherboard does not support IOMMU, so that's not a viable solution either.)

    If someone could help offer suggestions or troubleshoot this issue, I would really appreciate it! Thanks!

    As soon as you get it fixed by running the script, please post-
    Code:
    lspci -nnk | grep -iA2 net
    lsmod
    ifconfig
    dmesg | grep -iE 'r81|eth|network'
    Then, when it cuts out again, do -
    Code:
    ifconfig
    dmesg | grep -iE 'r81|eth|network'
    cat /var/log/syslog | grep -iE 'r81|eth|network'
    As soon as it cuts off, also take a look at -
    Code:
    cat /var/log/syslog | tail -40
    and post its output too if there are any relevant messages in it that are not covered in the last command output above.

    Hi there!

    I appreciate your help, but I didn't think I was going to get a response, so I already bought a new network card... Thanks anyway!

    Yeah, a response 4 days later.., I wasn't hoping for a response either.

    Hope the new card is happy with Linux

    Feel free to post back anytime if you need to get the onboard one working as well. I can't promise, but I'll try my best
