WiFi interface does not starts on boot
ar flag

I was toying around with hostapd and I don't know what I did but now on rebooting my wifi is not starting. ifconfig shows all the interfaces but the wlan0.
Right now I am using a workaround by running : sudo iw phy phy0 interface add wlan0 type managed everytime I boot.
How can I fix this?
