Hello, I am a new user in Ubuntu and I am getting crazy with the following problem.
After working for a few months, suddenly the wifi connection on my laptop ASUS UX303L stopped to be able to connect to all protected networks.

I suppose that the drivers are still there. The only thing I can attribute this to is the fact that I have recently installed the drivers libgcrypt11 to be able to use spotify.
Now, I do not know if this generated any conflict. I would just be happy to remove the drivers (and spoitify) but to have back the previous setup of the wifi.

Thank you for your answers!
