First of all, you have to find out which wifi hardware you have. You can find it using the lspci command from fedora terminal. It will list the hardware you have in your system. Look in the output and you can see your network controller. Example output

Network controller [0280]: Broadcom Corporation BCM4331 802.11a/b/g/n [14e4:4331] (rev 02)

Here, I am assuming that you have a Broadcom BCM4311 chipset. The b43 driver with the newer linux kernel 3.2+ supports the BCM4331 wireless card but the firmware is missing - device not ready (firmware missing). However, the only things needed to get it working are the b43-fwcutter (installed by default in fedora 17 the last time I checked) and the Broadcom proprietary driver tar file mentioned from here. Download that tar file and then issue the following commands:

tar xf broadcom-wl-5.100.138.tar.bz2
sudo b43-fwcutter -w "/lib/firmware" broadcom-wl-5.100.138/linux/wl_apsta.o

This will install the missing BCM4331 firmware for the b43 driver to /lib/firmware/b43, from where it will be picked up automatically on reboot. (not needed reboot in fedora 17 last time I checked.)
