linux(ubuntu11.10)与r8168网卡不兼容导致网络时断时续的问题

安装了ubuntu11.10之后，感觉上网啥的很不稳定，ssh连接内网机器也是一条命令卡半天，检查了各方面的原因，网络没有什么问题，最后才发现是网卡驱动的问题，网上搜了一下是由于linux(ubuntu11.10)与r8168网卡不兼容导致网络时断时续的问题，那就直接更新网卡驱动吧，下面是网上搜到的解决办法，贴出来，给同样问题的同志门，搞定之后那个心情是一个爽啊，哈哈……

 

first:make user to root.
$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
