HOW TO: Install Broadcom-sta (wl) driver in LMDE
I used method 3 after uninstalling the existing driver for the broadcom card installed by default (my Broadcom 4312 wireless card is low power and requires firmware-b43-lpphy-installer_4.174.64.19-4_all.deb instead of the default firmware-b43-installer... I marked that file for removal and applied the change using Synaptic Package Manager.This works for Ubuntu, Linux Mint XFCE and LMDE ...
To install the premade driver from Broadcom follow the instructions given by Broadcom for installation of the Broadcom-STA driver:
On a computer with Internet access, download the required firmware files from
http://downloads.openwrt.org/sources/wl ... 130.20.0.o
http://mirror2.openwrt.org/sources/broa ... .5.tar.bz2
Copy the downloaded files to your home folder and execute the following commands
consecutively in a terminal to extract and install the firmware:
open terminal
su (makes you a super user)
(note that the prompt is now a # hashmark)
Type the following commands (after the # prompt)
tar xfvj broadcom-wl-4.150.10.5.tar.bz2
sudo b43-fwcutter -w /lib/firmware wl_apsta-3.130.20.0.o
sudo b43-fwcutter --unsupported -w /lib/firmware broadcom-wl-4.150.10.5/driver/wl_apsta_mimo.o
I did not need to reboot. My device was recognized right away and I could connect without any activation...
I connected right away no troubles.
