How to Install Broadcom / STA Wireless card (BCM43XX)

I'm having trouble connecting to my home's wifi network, i've run the sudo lshw -C network command, and since I'm on another computer I can't type it all out but here's some info:

*-network  
description:Network controller  
product: BCM4312 802.11b/g LP-PHY  
vendor: broadcom corporation  

If any info is needed, ask, and I'll gladly provide it. I also noticed that under Additional Drivers in Settings, there's a Broadcom STA wireless driver that I can activate however when I click activate I get an error that says that the installation has failed. And I'm provided with a log file location to look at for details but I'm unsure of where to look for that path. How can I get connected to my network?

Check that page. In this case, Broadcom 4312 is supported by both b43 and wl. Make sure to run sudo apt-get update and then try to sudo apt-get --reinstall install bcmwl-kernel-source and tell me what happens in the command line. If it doens't work, you can also try sudo apt-get purge bcmwl-kernel-source followed by sudo apt-get install firmware-b43-installer to install the reverse-engineered b43 driver instead of the closed-source broadcom bcmwl module.
