Although I don't know what the other attempt has done.
I unchecked them in the start/settings/software sources > additional repositories tab, updated cache and it said I have some broken packages.. ah well..

he most simple method to install broadcom b43 wireless driver in LMDE

This method applies to kernels 3.5 and above and depends upon replacing Debian firmware-linux-nonfree with Ubuntu linux-firmware-nonfree_1.14_all.deb. Follow these steps:

1- Start by uninstalling firmware-linux-nonfree via Synaptic

2- Download Ubuntu linux-firmware-nonfree_1.14_all.deb by another machine with internet connection or by connecting your machine via wired connection or using another USB wireless.

The download link is http://www.ubuntuupdates.org/package/core/quantal/multiverse/base/linux-firmware-nonfree

3- Install the downloaded driver via Gdebi or dpkg as follows

dpkg -i linux-firmware-nonfree_1.14_all.deb

4- Reboot your machine and that is all

Downloaded the file "linux-firmware-nonfree_1.14_all.deb" to Downloads folder

from Downloads folder:

dpkg -i linux-firmware-nonfree_1.14_all.deb

Selecting previously unselected package linux-firmware-nonfree.

Unpacking linux-firmware-nonfree (from linux-firmware-nonfree_1.14_all.deb) ...

Now for a reboot and see what happens...

In the start/settings/driver manager, the
 Broadcom Corporation: BCM4313 802.11b/g/n Wireless LAN controller.
bcmwl-kernel-source (Version 6.3.0.223.141+bdcom-0ubuntu1. Broadcom 802.11 Limux STA wireless driver source
Is not active - tried to activate it and it didn't, it went back to:
Do Not use the device
It changes back when I click the click the "apply changes" button.

I'm running Linux Mint 14 Nadia. My wireless card is the BCM4331 on a Mac Mini (Macmini5,1). After installing this package I rebooted then I added a line that said simply "b43" to the file /etc/modules. Rebooted again. Clicked on the Wifi icon in the panel in the notification area and chose my Wifi network. Success! 

Try this and re-boot.
Didn't seem to work. I might have to do some reading and learn about what is really going on rather than try trying stuff.
