运行ifconfig wlan0 up回报
ifconfig: SIOCGIFFLAGS: No such device
我尝试ifconfig wlan0并得到了
ifconfig: wlan0: error fetching interface information: Device not found
启动日志显示
Starting network: [ 6.178148] ip (252) used greatest stack depth: 5756 bytes left
/bin/sh: wpa_supplicant: not found
FAIL
我该如何调试这个？有什么建议么？
