我的wpa_supplicant程序有问题。
我的问题是关于使用wpa_cli哪个需要wpa_supplicant。我执行时出错sudo wpa_cli：
Could not connect to wpa_supplicant
的手动启动wpa_supplicant给了我一些错误：
sudo wpa_supplicant -i wlan0 -c /etc/wpa_supplicant/wpa_supplicant.conf
rfkill: Cannot open RFKILL control device
ioctl[SIOCSIWAP]: Operation not permitted
ioctl[SIOCSIWENCODEEXT]: Invalid argument
ioctl[SIOCSIWENCODEEXT]: Invalid argument
wlan0: CTRL-EVENT-DISCONNECTED bssid=00:00:00:00:00:00 reason=0 ### NEW!!!
