Long story short, I was playing with things that I shouldn't have and had to do a fresh install of 12.04.
After going through How to Install Broadcom Wireless Drivers with no luck. Then, became sort of tired of waiting for this to get updated Ubuntu 12.04 on Dell Inspiron - Wireless stopped working. Also went through Broadcom 4312 wireless issues [duplicate]. Went through some other ones but I couldn't find them again. I have nearly given up. This is definitely a duplicate in some form, but none of the other solutions have worked for me.
Right now I have uninstalled bcmwl-kernel-source
and installed b43-fwcutter
and firmware-b43-lpphy-installer
.

Just another quick note. As I have it now, I am able to Enable and disable wireless by clicking on the menu options on the top left. It seems like the wireless is working but it is not picking up any networks. Would post a screenshot but it doesn't take it if the menu is open :/. Confirmed that wireless card is functional through Windows boot. Also double checked router with multiple devices.
Thanks in advance.
