WiFi Access Point

[Rodary Jacques]

I have an Intel wifi card correctly configured for Jessie, thanks to 
https://wiki.debian.org/fr/iwlwifi. I only need the Hotspot Access point, 
but I can't start it at boot time, nor change  its name and the WPA 
password. I can only switch from "wifi active" state "to access point 
active" after boot. 
Is there a way to create a  script (a systemd service?) so that the access 
point, with name and  password I choose, is started at boot.
        Sorry for my English
