I've tried this multiple times with no success...
I go through all the steps without receiving any error messages but, when I reboot, the wifi card is not recognized and no ndis0 interface is present.

In the README I follow the steps but am confused as to whether I should run ndisgen while "make attach" is still connected to /usr/src or if I should run ndisgen after running "make detach."

I've tried both ways with no joy.

I've done the above with fresh installations of PC-BSD 9.2 as well as FreeBSD 9.2.
