1.修改/etc/default/linux-restricted-modules-common
中的内容为
# This file is sourced from the linux-restricted-modules-common init
# script and is used to disable the link-on-boot feature, one module
# at a time. This can be useful if you want to use hand-compiled
# versions of one or more modules, but keep linux-restricted-modules
# installed on your system, or just to disable modules you don't use
# and speed up your boot process by a second or two.
#
# Use a space-separated list of modules you wish to not have linked
# on boot. The following example shows a (condensed) list of all
# modules shipped in the linux-restricted-modules packages:
#
# DISABLED_MODULES="ath_hal fc fglrx ltm nv"
#
# Note that disabling "fc" disables all fcdsl drivers, "ltm" disables
# ltmodem and ltserial, and "nv" disables both the nvidia drivers.
# You can also name each module individually, if you prefer a subset.
DISABLED_MODULES="ath_hal"
2.打开终端依次执行以下命令行
sudo apt-get update
sudo apt-get install build-essential
wget 'http://snapshots.madwifi.org/madwifi-hal-0.10.5.6-current.tar.gz'
tar zxvf madwifi-hal-0.10.5.6-current.tar.gz
cd madwifi-hal-0.10.5.6-r3835-20080801
cd madwifi-hal-0.10.5.6-r3835-20080801
make clean
make
sudo make install
sudo reboot
好了，您的ubuntu 8.04可以使用无线上网了。
