Why does Wi-fi drop out after reboot in Debian 8?

Question

Debian

Hey!
Installed Debian 8 on an ASUS laptop and, as expected, troubles started.
For starters, it does not see the Wi-fi card. I rummaged through the internet, found the firmware-realtek image, installed it, and it worked.
But now, after a reboot, the connection disappears and you need to delete it (connection) every time and recreate it (write login and pass).
It seems that this is not normal)).
Please tell me how to solve this problem.
Thank you.
