Good. I'm glad it helped. I'm not sure how or why akmods was deactivated, but it was bothering me for some time before I found a hint in an Nvidia thread that pointed me to systemctl. Hopefully, this will help others too.

Re: Broadcom-wl (BCM 4312 Chipset) broken after update

Thanks Ramiro!

I had the same problem, but with BCM4313 chipset on Debian and 3.5.0-4.dmz.1-liquorix-amd64 kernel. Your enlignment help to me to compile and build the driver manually.

Following your passes doesn't work for me at all, but I did the passes from REEDME file from broadcom webpage and one Fresh installation. Finally, It's working

I got the compilation from source working, in fact I'm posting this through the wireless interface. The modifications to the source file are really really simple.

If you want to try, it goes more or less like this:

1) get the source files from broadcom -- http://www.broadcom.com/docs/linux_s..._82_112.tar.gz

2) make a new directory and extract the source files
# mkdir hybrid-wl
# cd hydrid-wl
# tar -xvzf ../hybrid-portsrc_x86_64-v5_100_82_112.tar.gz

3) change to the problematic file directory
# cd src/wl/sys

4) fix the source file wl_linux.c (of course use your favourite editor):
# vi wl_linux.c
around line 43, remove the line
#include <asm/system.h>

search for the string
and replace it with

save the file, and try to compile

5) # cd ../../..
# make

If you are lucky things should work, and you'll have a file called "wl.ko" in the current directory. (I got these patches from the internet, not my own work.)

I then did

# mkdir -p /lib/modules/3.4.0-1.fc17.x86_64/extra/wl
# cp wl.ko /lib/modules/3.4.0-1.fc17.x86_64/extra/wl
# depmod -a
# modprobe wl

and I had to reconfigure the interface, inserting the network password again, but after that it's working.

Thanks, it works for me
