Recommend a wifi dongle for access point setup

@Wrechid

the setting you quoted is relevant only for creating ad-hoc network. for this to work you even don't need to install hostapd (and is also AP feature is not needed). so once you enter this into interfaces (assuming your wifi is on the list of "ifconfig" as wlan0), you just restart the interface (ifdown wlan0; ifup wlan0) - also assuming it is not in collision with your eth0 network while testing (if you have ethernet connected).

as soon as you restart the interface you should see wifi MYCARXBIAN in the list of available network from other devices.
