I have essentially no experience with wifi in FreeBSD so I can't really help 
you directly except to suggest doing pciconf -lv and check to see if it will 
list specific hardware details about the wifi card. No need to post all the 
output, just the section pertaining to the wifi card will suffice. 

This info may assist others in determining if/how they may be able to help
