Wifi stopped showing in linux mint

Yesterday night I had a problem with a usb port and the touch pad not working, I restarted the system a few times and switched back and forth with windows (which is installed on a different drive), they didn't work even there.After a few restarts the usbport and the touch pad came back to life, but the wifi stopped working. When I type wifi in the terminal I get: wifi = none (no device)
This time the problem is only on linux though.

Where/What should I check?
