    Slow speeds after upgrading to 13.10

    I have a problem with wired connection & NAS file copy. When connect with wifi adapter, surf internet very smooth and file copy to NAS server ~ 3-4MB/s. But with wired connection it too slow, file copy to NAS freeze.

    Code:
    lspci -nnk | grep -iA2 net

    Re: Slow speeds after upgrading to 13.10

    I try connect to router through 100mbps switch, file copy to NAS speed normally, internet surfing smooth.

    My router WZR-HP-AG300H, fw: dd-wrt.

    Also try Ubuntu gnome 13.10 amd64 & Xubuntu 13.10 amd64, same issue.
