No wireless in 9.10 with Broadcom BCM4312

[Gravy]

Hey Guys,

I'm having some problems with 9.10 on my Dell Mini 9. I'm a bit of a new comer to linux so if it's something obvious I apologise. If you can help me out thanks in advance.

Basically I'm not getting wireless as an option in the little network drop down thing. (very technical description )

I've tried some of the suggestions in this thread:
http://ubuntuforums.org/showthread.php?t=1309760

Well the following commands from that thread:

sudo apt-get upgrade
sudo aptitude reinstall bcmwl-kernel-source
sudo apt-get install update

The Broadcom STA driver now shows up in Hardware Drivers however has the following message at the bottom:

The driver is activated but currently not in use

sudo lshw -c network:

I'm guessing that UNCLAIMED bit probably is causing the problem. However I know nothing.

EDIT: I also just thought it might be worth mentioning. I couldn't get ubuntu to boot when using the usb-creator.exe. I created an USB drive with unetbootin and install was successful.
