I don't think complaining about the FreeBSD forum here is going to solve your issue. FreeBSD is not the forum. I use FreeBSD and have never joined nor used the forum, and I doubt I'm alone in that - it's irrelevant.
To address your problem, it seems to me that you're attempting to configure the wrong device.
Post the contents of your /etc/rc.conf or better yet read the freely available documentation:
