How to manually install Broadcom BCM4312 wireless drivers on Debian without an Internet connection

12Jul14

I installed Debian Wheezy on my netbook a couple of days ago and forgot to install the Broadcom wifi drivers, while I still had wired access. Now, this morning in the comfort of my bed I wanted to get online from my netbook and realized I have no working wifi on it. Luckily, I happened to have a second laptop with working wireless with me to use as the package downloader, downloaded the required packages to USB drive and copied them to my netbook.

These instructions are for the Broadcom BCM4312 driver, and these are the files you need to download:

1. b43-fwcutter (https://packages.debian.org/search?keywords=b43-fwcutter)
2. broadcom-wl-4.178.10.4.tar.bz2 (http://downloads.openwrt.org/sources/)

Keep in mind the broadcom-wl version is obviously going to change over time.

Once you have copied both files to your wireless-less computer, do the following:

$ sudo dpkg -i b43-fwcutter_XXXXXX_.deb
The XXXXXX depends on your version of the b43-fwcutter package

$ export FIRMWARE_INSTALL_DIR=”/lib/firmware”

$ tar xvjf broadcom-wl-4.178.10.4.tar.bz2

$ cd broadcom-wl-4.178.10.4

$ sudo b43-fwcutter -w “$FIRMWARE_INSTALL_DIR” ./linux/wl_apsta.o

If everything completed without errors, reboot your system and then enjoy your wifi. 🙂
