1.应急办法:查询rfkill list all,可以看到ideapad_laptop的无线被物理关闭,可是博主的笔记本根本没这个键位,所以执行sudo modprobe -r ideapad_laptop指令,可以把这个指令写入/etc/rc.local,内容如下
#!/bin/sh -e
# # rc.local # # This script is executed at the end of each multiuser runlevel. # Make sure that the script will "exit 0" on success or any other # value on error. # # In order to enable or disable this script just change the execution # bits. # # By default this script does nothing. #开机启动WiFi echo “你用户密码”|sudo modprobe -r ideapad_laptop exit 0
