我的笔记本是华硕x51l,请问,怎样在ubuntu中使用wifi呢?
要安装什么无线驱动程序?

sudo ifconfig -a
sudo gedit /etc/NetworkManager/NetworkManager.conf # 適用於 11.04 版
sudo gedit /etc/network/interfaces
把以上三個指令執行結果 貼上來

sudo ifconfig -a

sudo gedit /etc/NetworkManager/NetworkManager.conf

# This file is installed into /etc/NetworkManager, and is loaded by
# NetworkManager by default. To override, specify: '--config file'
# during NM startup. This can be done by appending to DAEMON_OPTS in
# the file:
#
# /etc/default/NetworkManager
#

[main]
plugins=ifupdown,keyfile

[ifupdown]
managed=false

sudo gedit /etc/network/interfaces
auto lo
iface lo inet loopback
auto dsl-provider
iface dsl-provider inet ppp
pre-up /sbin/ifconfig eth0 up # line maintained by pppoeconf
auto dsl-provider

sudo gedit /etc/network/interfaces

auto dsl-provider iface
dsl-provider inet ppp
pre-up /sbin/ifconfig eth0 up # line maintained by pppoeconf
auto dsl-provider iface

dsl-provider provider
dsl-provider

1. 最下面四行 是不是 多餘的 ？ 可以刪除 ？
auto dsl-provider
iface dsl-provider inet ppp
provider dsl-provider
provider dsl-provider

2. sudo ifconfig -a 中
eth0 Link encap:Ethernet HWaddr x(x代替) # 有啓動
ppp0 Link encap:Point-to-Point Protocol # 有啓動
但是 無綫沒啓動 可能是
無綫網卡 壞了
無綫網卡未從 bios 或 鍵盤 打開
驅動程式未正確安裝
