Hello
Thank you for your interest and sorry for delayed reply.
I tried to search on system profiler but I can not find references. I searched on network> wi-fi and I get this feedback
Software versions:
CoreWLAN: 11.0 (1101.20)
CoreWLANKit: 11.0 (1101.20)
Extra menu: 11.0 (1121.34.2)
System information: 12.0 (1100.2)
Family IO80211: 11.1 (1110.26)
Diagnosis: 5.1 (510.88)
AirPort Utility: 6.3.6 (636.5)
I do not know where to look for the type of card
