一、笔记本电脑配置

一台很老的联想笔记本，闲来无线，配置下，用于无线抓包。

整体就是一个字：经典。

二、安装环境

安装aircrack ，我们用于正经的抓包，不做其它用途。

三、配置方法

1、注意无线网卡接上去后，看下网卡名称

wlan1     Link encap:Ethernet  HWaddr cc:d2:9b:35:6f:1d  
          UP BROADCAST MULTICAST  MTU:1500  Metric:1
          RX packets:0 errors:0 dropped:0 overruns:0 frame:0
          TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000 
          RX bytes:0 (0.0 B)  TX bytes:0 (0.0 B)

2、注意不要使用无线网卡直接连接无线，因为要保证airmon-ng对于无线设备的独占配置。当然可以在网络连接中，清除无线的配置。

由于版本较老，没有airmon-ng check kill的支持，手动kill。

配置要抓取的无线信息（可选步骤）

3、配置无线网卡为侦听模式
