It's an AR9285 on FreeBSD-8.2-STABLE-amd64, also happens on  
FreeBSD-9.0-BETA3.

I was actually expecting to see around 30 networks by default as...  
well, it's a UNIX-like OS.

I'm still trying to get my environment set up, and there's a lot to  
do.  However this installation is still pretty default, I really don't  
see why it doesn't work.  If any kind of diagnostic output would be  
helpful to you just provide the commands you need me to issue and I'll  
return it.
