Can't find the solution of network adapter in win10 system device manager

Device Manager does not have a network adapter solution:
1, check the hardware switch;
2, check Fn + F5 to see if the wireless network card is turned off;
3, the above settings are no problem, uninstall all wireless NIC driver and software. Restart, and then install the driver (in order to avoid the INTEL network card nerve, please customize the installation, my reason is because of the missing WIFI STA components, resulting in numerous experiments);
4, after the last 3 steps or not, Please uninstall all wireless network card drivers and software. Then shut down. Take out your Phillips screwdriver, open the cover on the hard drive (the one below the touchpad) and remove the wireless card. Do not install the back cover;
5, boot, fully enter the system, directly install the wireless network card (be careful not let the sweaty hand touch other hardware, or short circuit burned);
6, after closing Cover and install the driver.
