Wireless Network -- FreeBSD 9.0

[southpaw63119]

I decided to try out the FreeBSD operating system, so I originally installed it in a VirtualBox machine and found that I kind of liked it (despite having to wait so long to compile things and being unable to figure out how to use pkg_add).
Now I am trying to get a FreeBSD system set up on my desktop, but I cannot get the wireless card to work quite right.

I need to connect to a PEAP authenticated network.
The wireless card is D-Link DWA-140 REV B, which means that it uses the rt2870 chipset...
The version of FreeBSD is FreeBSD 9.0 RC2.

Any help would be much appreciated--I've tried reading through a few things, and only came out more confused.

Here are the contents of my /boot/loader.conf file:

if_run_load="YES"
runfw_load="YES"

And here are the contents of my /etc/rc.conf file:

hostname="WTBSD"
sshd_enable="YES"
ntpd_enable="NO"
wlans_run0="wlan0"
ifconfig_wlan0="ssid PurpleNet DHCP"

When I run ifconfig, information does appear for wlan0, but I have not been able to figure out how to set it up to work with a PEAP network...
