E5-575-33BM WiFi specification

Hi! Like the title says, need to know the wifi specification. In acer drivers section, you must choose between
two drivers: Atheros wifi driver or Intel wifi driver. It makes me think that some models of the e5-575-xxxx have the atheros, and the other models have intel.
Couldn't find a way to get that spec and that's what I came here to ask.
Thank you!
