Your wifi card seems to be recognised. The easiest way to set up your wifi would be to install wicd from the install DVD. Wicd is in /extra
Wicd is an easy to use GUI program that will help you set up your wireless connection.
Try to install it first with:
Code:
# installpkg /path/to/wicd-blah-blah.txz
Obviously the path and the exact name of the file will be different.
Once you've installed wicd, see if you can set it up. If not, post here where you're stuck.
