I have a Dell XPS running windows 10. When I go into settings, The wi-fi was working and then suddenly it wasn't. It has turned off and won't be turned back on. I can slide the Wi-fi slider to "on" but it doesn't actually turn on and then the slider goes back to "off". I have restarted and cold started several times. I have checked "turn wi-fi on in 1 hour" and waited. I have disabled and enabled both wi-fi and ethernet. Nothing is working.
