Debian Hardware :: Load Firmware For BCM Card With No Internet Connection

I performed an update that has caused issues with my wireless. Errors relating to wireless firmware missing and consequently no internet connection.

I've been through this before with my 2008 macbook air BCM card whose firmware isn't included in installs. In the past I've manually installed the b43-fwcutter package an extracted some firmware... That doesn't seem to be working here.

I've used [URL]i ... cefirmware to troubleshoot. I have not been able to get b43 or wl to work.

I attempted to install the "firmware-b43-installer_015-14.1_all.deb" package; however it depends on wget to download and install "broadcom-wl-5.100.138.tar.bz2" from wlfinger.com.

So I manually installed b43-fwcutter and used it to extract the broadcom-wl-5 file referenced....

modprobe wl says wl doesn't exist and modprobe b43 doesn't seem to work.

Building only for 3.2.0-4-amd64
Module build for the currently running kernel was skipped since the
kernel source for this kernel does not seem to be installed.

I tried something from broadcom that produced make errors "/lib/modules/3.2.0-4-amd64/build: No such file or directory"... I think this means I need some kernel development packages, broadcom says:

Code: Select allOn Fedora install 'kernel-devel' (Development Package for building kernel
modules to match the kernel) from the Package Manager (System->
Administration-> Add/Remove Software).

On Ubuntu, you will need headers and tools.  Try these commands:
# apt-get install build-essential linux-headers-generic
# apt-get build-dep linux

I'm having trouble install this stuff without the net and not sure installing generic headers and build-dep outside of apt-get is the way to go... linux-headers-3.2.0-4-amd64_3.2.57-3+deb7u2_amd64.deb has alot of dependencies that would take me a while to find and download.
