    Question Wired network becomes 10MB Half Duplex after resume from suspend

    Hello,
    I really need help with this one;
    I have wired 100 MB from my ubuntu 10.04 with kernel 2.6.32-33-generic.
    After i suspend the system and then wake the system,
    Eth0 becomes 10MB half duplex.
    dmesg doesnt tell me much:

    [ 112.796601] r8169: eth0: link up
    [ 112.797941] ADDRCONF(NETDEV_CHANGE): eth0: link becomes ready
    [ 123.130022] eth0: no IPv6 routers present
    [ 182.507840] r8169: eth0: link down
    [ 185.050564] r8169: eth0: link up

    dj@diskoteket:~$ sudo ethtool eth0

    If reboot the system, the network works just fine.
    Anyone? Please!
    Thank you

    I fixed this by installing correct drivers for my realtek RTL8101E/RTL8102E card.
    Google It!
