I'm using Debian 8 and WiFi has stopped working.

When I look for the networks by the gnome it appears that there are no available networks, I've tried a lot but it does not work again.

I already installed the drivers (it was working) I do not know why it stopped working. I do not want to format the computer

The problem was in the wpa_supplicant.service that was not starting. After finding the problem was easy, with some commands everything is working.

wpa_supplicant.service was not able to access libssl1.0.2

Solution:

apt install --reinstall libssl1.0.2 <br>
service wpa_supplicant restart <br>
reboot
