final solution:
http://ubuntuforums.org/showthread.php?t=1022411This is guidance for those with integrated Realtek RTL8111 series gigabit Ethernet, built in to motherboards such as the ASRock G41M-LE.Ubuntu 8.10 (and may other versions) have been reporting problems with connectivity. Here is the solution in a walk-through format. You must be root (sudo su -).1) Check to see if the r8169 module is loaded-> lsmod | grep r816r8168 41104 0
-> lspci -v01:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168B PCI Express Gigabit Ethernet controller (rev 03)
Subsystem: ASRock Incorporation Device 8168
Kernel driver in use: r8169
Kernel modules: r8169
2) Download the official Realtek driverRealtek RTL8111/RTL81683) Remove the r8169 module-> rmmod r8169
-> mv /lib/modules/`uname -r`/kernel/drivers/net/r8169.ko ~/r8169.ko.backup( the ` is a backtick, it is not an apostrophe or single quote )
4) Build the new r8168 module for the kernel-> bzip2 -d r8168-8.009.00.tar.bz2
-> tar -xf r8168-8.009.00.tar
-> cd r8168-8.009.00
-> make clean modules
-> make install5) Rebuild the kernel module dependencies-> depmod -a
-> insmod ./src/r8168.ko6) Remove the r8169 module from initrd-> mv /initrd.img ~/initrd.img.backup
-> mkinitramfs -o /boot/initrd.img-`uname -r` `uname -r`7) Add r8168 module to /etc/modules-> echo "r8168" >> /etc/modules8) Reboot, You are done!9) Examine that ONLY the r8168 module is loaded for the interface-> lspci -v01:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168B PCI Express Gigabit Ethernet controller (rev 03)
Subsystem: ASRock Incorporation Device 8168
Kernel driver in use: r8168
Kernel modules: r8168
Actions as needed in fact:
1. download driver;
2. untar and ./autorun.sh
Ok, it's all done.
sudo /etc/init.d/networking restart
sudo ifconfig eth0 down/up
nm-tool
cat /var/log/message
cat /var/log/syslog
dmesg
lspci
lsmod
lshw
dmidecode
biosdecode
cat /proc/cpu
vi /etc/network/interfaces
auto eth0
The solution
- Boot up Windows
- Right click on My Computer
- Click on Properties -> Hardware -> Device Manager
- Expand your network card section and double click on your Realtek network card
- Set "Wake-on-lan after shutdown" to enabled
i removed r8169 and installed r8168
this can be done by downloading it from the realtek-website.
the problem afterwards was that r8169 was coming back after a restart. The solution for this problem can be found here :

thanx for the answer.
I had the same problem. I had to use Google for a long time, till i found a solution in a german forum (i am from germany; sorry for my english if it's too bad). Here are the instructions:
First, you need to rename the r8169 driver, because it won't work with this one.
> mv /lib/modules/`uname -r`/kernel/drivers/net/r8169.ko /lib/modules/`uname -r`/kernel/drivers/net/r8169.ko.old
> depmod -a
To save the current ramdiscimage and make a new one:
> mv /boot/initrd.img-`uname -r` /boot/initrd.img-`uname -r`.old
> mkinitramfs -o /boot/initrd.img-`uname -r`
Now you have to reboot. After this, it worked for me. To see weather the right module is loaded, you can use this:
> lsmod | grep r81*
There it showed me the right module, r8168.
==============
The device eth0 is not ready!
记得我的电脑是在一次升级之后出现的这种情况，之前都使用得非常好，觉得可能是安装了一些中文汉化升级包，防火墙的一些英文参数发生了变化。不过还好，本人从网上找到了一些相关的帖子，解决了问题，本人验证过。
在终端中输入： sudo gedit /etc/firestarter/firestarter.sh
在 # External network interface data
这行注释的上面，添加一行：
LANG=en_US
保存后（不须重启），firestarter就可以顺利启动，正常工作了，再也没有那烦人的提示。
注意：在加入LANG=en_US之后，如果再运行firestarter的运行向导，则先前加入的LANG=en_US会消失，错误问题会和以前一样出现，防火墙不能用，你须要再一次加入LANG=en_US

Suspend causes eth0 to disconnect intermittently
Install WICD (System > Administration > Synaptic Package Manager; install wicd).
Uninstall network manager (mark for complete removal network-manager and network-manager-gnome). Reboot.
