    r8168 on Ubuntu 11.10 Kernel 3.x.x, part 2

    On Unbuntu 11.10, 3.0.0-14-generic:

    I've followed the steps above to change my kernel module to load r8168 instead of r8169. However, I'm still getting dropped connectivity on the ethernet connection.

    Network-Manager also keeps complaining with popups with "Wired network\n Connection Established" and "Wired network\n Disconnected".

    I checked the syslog and it doesn't report eth0 going down or up, so I assume it stays up.

    I am sharing my wifi connection on my computer to computers with this ethernet card attached to a switch. On the other computer, icmp_seq is inconsistent when I ping a website and sometimes gets dropped:

    64 bytes from ( icmp_seq=5 ttl=50 time=29.4 ms
    64 bytes from ( icmp_seq=9 ttl=50 time=23.0 ms
    64 bytes from ( icmp_seq=12 ttl=50 time=36.7 ms
    64 bytes from ( icmp_seq=13 ttl=50 time=23.7 ms
    64 bytes from ( icmp_seq=16 ttl=50 time=22.3 ms
    64 bytes from ( icmp_seq=17 ttl=50 time=19.5 ms
    64 bytes from ( icmp_seq=20 ttl=50 time=23.9 ms
    64 bytes from ( icmp_seq=21 ttl=50 time=21.4 ms
    64 bytes from ( icmp_seq=24 ttl=50 time=53.5 ms
    64 bytes from ( icmp_seq=28 ttl=50 time=34.1 ms
    64 bytes from ( icmp_seq=32 ttl=50 time=23.5 ms
    From icmp_seq=33 Destination Port Unreachable
    64 bytes from ( icmp_seq=35 ttl=50 time=26.2 ms
    64 bytes from ( icmp_seq=39 ttl=50 time=23.9 ms
    64 bytes from ( icmp_seq=43 ttl=50 time=99.5 ms
    64 bytes from ( icmp_seq=47 ttl=50 time=31.1 ms

    Anyone experiencing this issue?
