[ubuntu] Wireless card not supported?

view full story

http://ubuntuforums.org – I just recently installed Ubuntu on my wife's computer, and per her request I removed windows. She is now stuck without internet. She has a Dell studio with a BCM4312 and it appears Ubuntu doesn't even recognize it. I'm afraid wireless is the only way to connect to the internet on that laptop so I can't even get the new updates that I just got on my laptop. Is there any way to resolve this? Please help me keep from getting scolded. (HowTos)
