方式1：网卡通过DHCP自动获取IP地址
方式2：网卡静态分配IP地址
方式3：PPPoE宽带拨号配置
方式4：通过无线局域网接入互联网
方式1：网卡通过DHCP自动获取IP地址
$ sudo gedit /etc/interfaces
# 修改文件/etc/interfaces如下文
#-------------------------------------------------------------------------------
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).
#
# The loopback network interface（配置环回口）
auto lo # 开机自动激lo接口
iface lo inet loopback # 配置lo接口为环回口
# The primary network interface （配置主网络接口）
auto eth0 #开机自动激活eth0接口
iface eth0 inet dhcp #配置eth0接口为DHCP自动获取
#-------------------------------------------------------------------------------
$ sudo /etc/init.d/networking restart # 重启网络
方式2：网卡静态分配IP地址
$ sudo gedit /etc/interfaces
# 修改文件/etc/interfaces如下文

$ sudo /etc/init.d/networking restart # 重启网络
方式3：PPPoE宽带拨号配置
首次拨号：
sudo pppoeconf
系统开始搜索所有网络接口上的adsl modem,一步步的yes过来。
│ Please enter the username which you usually need for │
│ the PPP login to your provider in the input box below. │
│ If you wish to see the help screen, delete the │
│ username and press OK. │
输入你的宽带帐号。
输入密码。
tip：如果是河南网通提供的PPPoE宽带帐号，此处输入的是加密后的用户名
Would you like to add these addresses automatically to the list of nameservers
in your local /etc/resolv.conf file? (recommended)
是否自动获得DNS，选择是。
Should pppoe clamp MSS at 1452 bytes? If unsure, say yes.
数据包长度的设置，如果跟我一样不确定，选择是
Your PPPD is configured now. Would you like to start the connection at
boot time?
是否启动时自动激活ADSL？ 各位看着办吧。
#p#副标题#e#
以后，要手工拨号，打开终端，输入命令：
sudo pon dsl-provider
一般情况下，一次拨通后以后登陆ubuntu都会自动拨通上网的了，不用每次都输入命令拨号。
手工断线：
sudo poff
查看连接情况：
plog 和 ifconfig ppp0
ifconfig ppp0 可查询本机的上网IP。
方式4：通过无线局域网接入互联网
要求安装有无线局域网卡并已驱动
1.插入无线网卡
查看一下网络设置，看看是否多出来了两个设备
