I have Raspberry Pi 3 and I tried to config for auto connect to wifi like this example
http://weworkweplay.com/play/automatically-connect-a-raspberry-pi-to-a-wifi-network/
but when I finish, I got "No wireless interfaces found" when I click wifi symbol. However if I comment them out and back to default config( no auto wlan0 ... ), my wifi is back.
How can I fix this ?
