wlan_11n无线配置

    把这几天使用无线的过程写下来，岁数大了，忘性太严重。

1. 无线配置

[root@localhost /]# ifconfig eth0 down     ;首先关闭有线网卡
[root@localhost /]# wlanconfig ath0 create wlandev wifi0 wlanmode sta ;如果没有无线则创建
[root@localhost /]# ifconfig ath0 up          ;启动无线网卡ath0
[root@localhost /]# ifconfig             ;查看无线信息，出现HWaddr 00:12:34:56:78:90
[root@localhost /]# iwlist ath0 scan
