I have been following some instructions on how to get the wireless card working on my early 2011 MBP running Ubuntu 11.10. These can be found here.

I get to the following steps:

Extract the firmware:

$ tar xf ../broadcom-wl-5.100.138.tar.bz2

$ export FIRMWARE_INSTALL_DIR="/lib/firmware"

$ sudo ./b43-fwcutter -w "$FIRMWARE_INSTALL_DIR" broadcom-wl-5.100.138/linux/wl_apsta.o

$ cd ..

and the following error is produced in terminal:

sudo ./b43-fwcutter -w ¨$FIRMWARE_INSTALL_DIR¨ broadcom-wl-5.100.138/linux/wl_apsta.o

This file is recognised as:

filename : wl_apsta.o

version : 666.2

MD5 : *****************

Extracting b43/lp0initvals14.fw

failed to create output directory: No such file or directory

What am I missing? Any help would be appreciated as I would like to be able to make my laptop a portable machine running Ubuntu. Currently, it is a desktop laptop machine...

Try to create the directory /lib/firmware first (at least I guess that's why it fails; I might be wrong):

sudo mkdir -p /lib/firmware

I can confirm that the Broadcom Corp. drivers work for a Macbook Pro 5,2 model under 12.10. I had to wrestle with the drivers in 12.04, but under 12.10 (with the kernel updates and all) I simply had to install them from Software Sources -> Additional Drivers.
