RTL8111/RTL8168 Network Connection Fix

This 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 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
-> 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
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: r8168
Kernel modules: r8168

网络设置

1、设置IP地址：

命令行下敲：sudo gedit /etc/network/interfaces

并添加如下内容：

auto lo

iface lo

inet loopback iface eth0 inet static

address 192.168.1.169

netmask 255.255.0.0

gateway 192.168.1.1

auto eth0

 然后保存退出

2、设置DNS服务器

命令行下敲：

sudo gedit /etc/resolv.conf

在里边加入如下内容：

nameserver 202.117.128.2

添加完成后保存退出。

这些都修改完成后，重启网络，命令：

sudo /etc/init.d/networking restart

完成重启就可以。

如果你使用的是ADSL设置的话，详细情况看 http://wiki.ubuntu.org.cn/ADSLPPPoE有详细介绍。

每次修改完成后重启网络使修改生效 http://sunjsp.com。

重启网络的命令为：sudo /etc/init.d/networking restart

 

网卡无法重启

sudo /etc/init.d/networking restart * Reconfiguring network interfaces...

eth0: ERROR

while getting interface flags: No such device

SIOCSIFADDR: No such device eth0: ERROR while getting interface flags: No such device SIOCSIFNETMASK: No such device SIOCSIFBRDADDR: No such device eth0: ERROR while getting interface flags: No such device eth0: ERROR while getting interface flags: No such device Failed to bring up eth0.

 

 解决办法： sudo rm -rf etc/udev/rules.d/70-persistent-net.rules&reboot

If you need to, configure your /etc/network/interfaces for dhcp or static address then `sudo ifup eth0`
