I've intermittent packects dropped. I've tried to replace network cable, change switch port and use Realtek official r8168 driver but problem still here. HELP.....{:soso_e118:}

First  be sure what type of network adapter it is.
You can type the command lspci .
root@U-NAS:~# lspci
00:00.0 Host bridge: Intel Corporation N10 Family DMI Bridge (rev 02)
00:02.0 VGA compatible controller: Intel Corporation N10 Family Integrated Graphics Controller (rev 02)

01:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168B PCI Express Gigabit Ethernet controller (rev 03)


You can see  RTL8111/8168B PCI Express Gigabit Ethernet controlle is the network adapter.

Then  use command "lsmod  |grep  r816*"  to list which networking driver has been loaded.

root@U-NAS:~# lsmod |grep r816*
r8168                 175172  0
r8169                  35025  0
mii                     4525  1 r8169

Remove all of the networking drivers ,and reload r8168.
root@U-NAS:~# rmmod r8169
root@U-NAS:~# rmmod r8168
root@U-NAS:~#modprobe  r8168
root@U-NAS:~# /etc/init.d/networking restart
root@U-NAS:~#update-initramfs -u

Thanks. But I've no luck, the problem sill exist with r8168 driver. Any idea?

After my days of painful trouble shooting on the intermittent packets drop and network freeze issue, the on-board network port is now totally gone lastly (may be lucky). There is no link signel anymore. Will ask for hardware support. Thanks.

Maybe you can take discharge on the mainboard.
