Brand new ubuntu user. Downloaded 12.04 onto my HP nc6400. Everything looks great, except I can't get my wireless to work. Ethernet is working fine. I've searched everywhere, but none of the answers I've found make sense.

At the terminal I typed the command sudo lshw -C network

This is the result:
