WiFi won't connect to any network

Since a couple of days ago, I began having this problem.
I never touched my NIC and the antenna is still perfectly put.
The system is able to find WiFi networks (my home modem, my phone if I turn Tethering on), but it won’t connect.
After a while trying to establish a connection I receive a notification that says “Wireless Interface (wlp2s0) - The WiFi network could not be found”.
My other devices have no problem with this. I really don’t even know how should I debug something network related, so any help would be appreciated.

Hey, try putting airplane mode on and back. It solved the problem for me hope it works for you.
