WPA CLI

终端手动连接 Wifi。
检查无线网卡信息
qii@ubuntu:~$ iwconfig wlan0
wlan0 IEEE 802.11bgn ESSID:"Ubuntu-wiki-wpa-cli"
Mode:Managed Frequency:2.412 GHz Access Point: D3:1D:3C:11:A2:A1

重启无线网卡
sudo ifconfig wlan0 down sudo ifconfig wlan0 up
搜索接入点
sudo iwlist wlan0 scanning
返回接入点列表，类似这样的
wlan0 Scan completed :

注意这一行，这行就是接入点的 ESSID
ESSID:"Ubuntu-wiki-wpa-cli"
设定要连接的接入点，替换下列的ESSID
sudo iwconfig wlan0 essid ESSID
密码
sudo iwconfig wlan0 key s:密码
警告: 密码最好由字母和数字组成，你要是设的密码有!/#%$^#这类字符，这里会逼疯你的，这些特定字符会被Bash直接处理而不当作参数，出现bash: !~'": event not found 或 Error for wireless request "Set Encode" (8B2A) :
invalid argument ，试试加“”或' '，如果还不行，自己看着办吧。
，
然后是自动获取 IP
sudo dhclient wlan0
