4, analysis of the problem

As expected, it should be your NIC using the wrong driver, see the contents of the Red font:

Your network card is "rtl8111/8168/8411 PCI Express Gigabit Ethernet Controller", should not use r8169 this kernel driver module to drive, otherwise the phenomenon you now get the DHCP IP address, But the network card has been in constant "r8169 0000:03:00.0 eth0:link up" state. This makes it impossible to use a wired network.

The right driver to download to the Realtek website, install it yourself.
Http://www.realtek.com.tw/downloads/downloadsView.aspx? Langid=1&pnid=13&pfid=5&level=5&conn=4&downtypeid=3&getdown=false#2

Select the "LINUX driver for Kernel 3.x and 2.6.x and 2.4.x" version of the "8.038" file download under the UNIX entry in the above link. Download the files, unzip them into your home directory, and then execute the following commands in your home directory:

Code:CD r8168-8.038.00
sudo./autorun.sh

The driver installation is complete, reboot the system. Your wired network should be normal.
