Wireless option gone

I've got a Broadcom BCM4036 wireless card, as follows:

01:09.0 Network controller: Broadcom Corporation BCM4306 802.11b/g Wireless LAN Controller (rev 02)
Subsystem: Linksys Device 0013
Flags: bus master, fast devsel, latency 32, IRQ 5
Memory at fdefc000 (32-bit, non-prefetchable) [size=8K]
Capabilities: [40] Power Management version 2
Kernel modules: ssb

I'm running Ubuntu 11.10.

My wireless card hasn't worked so far (I installed Ubuntu this afternoon), and I've tried various things to make it work (including the answer to this question, and this help page), and it seems that one of them made the wireless option disappear. There's nothing in my additional drivers to enable (other questions mention needing to enable Broadcom STA wireless driver, but I don't see that option).

How do I get it back? More importantly, how do I get my wireless card working?

Do let me know if there's any information you need.

Clean out your old drivers if any that are lurking around by open a terminal Hit your super key and type Terminal

then 

sudo apt-get remove b43-fwcutter firmware-b43-installer
sudo apt-get remove bcmwl-kernel-source

Then type

sudo apt-get update

sudo apt-get install  bcmwl-kernel-source

This should then rebuild your Broadcom drivers for you in your terminal

To save you having to reboot try 'switching on ' your wireless by typing 

modprobe wl

alternatively if you want to the B43fwcutter again instead type 

sudo apt-get install b43-fwcutter firmware-b43-installer

If you get any errors let us know directly here in the comments. This should be sortable and should be quite easy to do so too. :) but I know it used to frustrate the heck out of me
