Eventually I got it.

1. Ubuntu couldn't recognize Intel(R) 82566 DC-2Gigabit Network Connection

2. http://downloadcenter.intel.com/Deta...=9180&lang=eng
from this site, I downloaded the driver(e1000) for my Intel ethernet controller and installed as the manual(README).

a. Move the base driver tar file to the directory of your choice. For
example, use /home/username/e1000 or /usr/local/src/e1000.

b. Untar/unzip archive:
tar zxf e1000-x.x.x.tar.gz

c. Change to the driver src directory:
cd e1000-x.x.x/src/

d. Compile the driver module:
(make sure you should log in as root, otherwise manythings can't be installed or removed.)
make install

The binary will be installed as:
/lib/modules/<KERNEL VERSION>/kernel/drivers/net/e1000/e1000.[k]o

The install locations listed above are the default locations. They
might not be correct for certain Linux distributions.

e. Load the module using either the insmod or modprobe command:
(log in as root, otherwise you can see 'Fatal Error inseting e1000, operation not permitted')
modprobe e1000
insmod e1000

3. and then I saw wired network connection signal
