centos 命令行 连接无线网卡

ifconfig wlan0 up

1	ifconfig wlan0

 

iwlist wlan0 scan

 

wpa_passphrase naizhongnai naizhong >> /etc/wpa_supplicant/wpa_supplicant.conf 

 

很奇怪，将wpa_supplicant的配置文件中wpa_supplicant.conf中的：
ctrl_interface=/var/run/wpa_supplicant
注释掉，竟然没有上面所说的错误了

 

 

-----------------------------------

ifconfig wlan0 up

service NetworkManager stop

service network restart

 

1	wpa_supplicant -i wlan0 -c /etc/wpa_supplicant/wpa_supplicant.conf  -D wext -B

 

iwconfig

dhclient wlan0

ping baidu.com
