我的集成网卡RTL8111/8168B终于搞定（非常感谢ubuntu中文论坛）

           由于工作关系，需要安装ubuntu11.04，可是网络一直不稳定，经常掉线（同事的网络灰常），ARM板和PC的tftp服务灰常不稳定，时而可以，时而不行，灰常郁闷，在网上终于找到一篇文章，跟我碰到问题一样，于是一步一步照着做，现在网络灰常稳定，再次感谢他们。

$su -root

1) Check to see if the r8169 module is loaded
-> lsmod | grep r816
r8168 41104 0
-> lspci -v
01:00.0 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 driver
Realtek RTL8111/RTL8168

3) 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 （这儿的包名称有点儿变化,需要改动）
-> tar -xf r8168-8.009.00.tar
-> cd r8168-8.009.00
-> make clean modules
-> make install

5) Rebuild the kernel module dependencies
-> depmod -a
-> insmod ./src/r8168.ko

6) 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/modules

Reboot, You are done!

9) Examine that ONLY the r8168 module is loaded for the interface
-> lspci -v
