Thread: dropped packets with realtek nic

  1. dropped packets with realtek nic

    I'm seeing dropped packets on eth0 (wired connection).
    I installed a x86_64 2.6.24.7 kernel (2008.1) because i read it may help
    that problem but in my case after rebooting to the new kernel things are
    the same. I power cycled the router "just in case" but that didnt change
    anything, also other pc's connected to the router are ok and not showing
    any dropped packets at all.
    If i run: watch -n 1 'ifconfig' the dropped packet count can be seen
    rising over 120 million per second. This has to be bogus, I can ssh to the
    system, open web pages and so on without any trouble. But it bugs me. Here
    are two snapshots taken 10 seconds apart. The onboard nic is a
    Realtec 'RTL8111/8168B PCI Express Gigabit Ethernet controller rev 02'

    eth0 Link encap:Ethernet HWaddr 00:E0:4D:8F:E4:79

    Any ideas?

    Ok, i solved it. I downloaded the realtek kernel module from the realtek web
    site, compiled it, installed it and no more dropped packets.

    FWIW I had the same problem (and solution) with 2007.1 and 2008.0, but
    2008.1 seemed to fix it.
