connecting to internet on beagleboard

I am currently having problems connecting to the internet with my
beagleboard. I have a Belkin wireless USB adapter which does not seem
to show up.

All I really need is an IP address for my laptop to reference in some
code so that I can send images from a camera I have connected to the
beagleboard. However, when I iwconfig nothing shows up.

I am using a custom image that uses modues 2.6.32 and:

The rt73 and rt2500 drivers seem to be present.

Everything else works (OpenCV, camera, and serial communication with
my robot).

Any ideas?
