How do I get a Broadcom BCM4312 working on a Dell XPS M1330?

Question

I have installed Ubuntu 14.04 on my laptop. When I plug in the ethernet cable the internet works fine, but I can't see any wireless network in the networking manager. The wifi switch is definitely on on my laptop! It's a Dell XPS M1330. [Edited: the network card is Broadcom Corporation BCM4312 802.11b/g ]

nm-tool gives me this:

Can you add the kind of wireless card it is to your question? — Jorge Castro, Jun 09 '14 at 21:30

Okay, once I found out the wireless card name I was able to find the answer. I needed to do sudo apt-get update and after that the drivers appeared under "additional drivers". Thanks!
