Getting Firmware missing on broadcom fedora 17

broadcom fedora 17.So, I’ve just installed Fedora 17, no great changes in UI, but it’s nice. Now, as always, the problem I get is to set up wireless on laptop(I love my old Dell Inspiron 1545) which uses a broadcom 4312. In case, you are having the same issue, you can follow the procedures below or follow the links found at the end of this post.

First, ensure you have b43-fwcutter,

yum install b43-fwcutter

Now, perform the following:

1 export FIRMWARE_INSTALL_DIR="/lib/firmware"
2 wget http://www.lwfinger.com/b43-firmware/broadcom-wl-5.100.138.tar.bz2
3 tar xjf broadcom-wl-5.100.138.tar.bz2
4 sudo b43-fwcutter -w "$FIRMWARE_INSTALL_DIR" broadcom-wl-5.100.138/linux/wl_apsta.o
