1. 下载
   Download the latest madwifi snapshot. // Google it

2. 解压
   $ tar zxvf madwifi-hal-0.10.5.6-current.tar.gz

3. 编译安装madwifi // 首先通过apt安装编译环境
   $ sudo aptitude install build-essential linux-headers-$(uname -r)
   $ make
   $ sudo make install

4. 安装module
   $ sudo modprobe ath_pci

5. 使网卡每次开机时都加载, make it load every time you boot
   $ sudo vi /etc/modules
   添加一行，如下
     ath_pci

6. 重新启动机器
   $ sudo reboot

注释 && 备忘
1. 为保证生效，重启前确认已屏蔽ath5k（默认驱动程序有可能是这个）
   检查是否已安装ath5k
   $ lsmod |grep ath5k
   有，则添加到blacklist
   $ cat /etc/modprobe.d/blacklist.conf
     blacklist ath5k
2. 确认安装驱动是否成功
   $ lsmod | grep ath_pci
     ath_pci               201176  0
     wlan                  193392  5 wlan_wep,wlan_scan_sta,ath_rate_sample,ath_pci
     ath_hal               300768  3 ath_rate_sample,ath_pci
3. 硬件型号查看
   $ lspci |grep Ethernet
     00:19.0 Ethernet controller: Intel Corporation 82566MM Gigabit Network Connection (rev 03)
     03:00.0 Ethernet controller: Atheros Communications Inc. AR242x 802.11abg Wireless PCI Express Adapter (rev 01)
4. ath5k是madwifi替代品，除非ath5k下无法连接无线，不建议使用madwifi
