Fedora Core 15 - Dell Studio 15 - Broadcom Wireless internet

Massive problems getting my wireless working on the latest and greatest Fedora Core 15! I was upgrading from FC13 and the previous broadcom-wl drivers were not supported on the new kernel. Here is how I fixed it.

Check that your card is supported
lspci -nn
04:00.0 Network controller [0280]: Broadcom Corporation BCM4313 802.11b/g LP-PHY [14e4:4727] (rev 01)

Download the hybrid driver source http://www.broadcom.com/support/802.11/linux_sta.php
Follow the readme steps to disable any existing configuration

Untar and try to make (this will probably fail do you to an error with the source with the c compiler. To resolve find line 485 and replace
init_MUTEX(&wl->sem);
with
sema_init(&wl->sem, 1);
FYI - I read that on another blog but lost the link.

run make again and this time you should be able to compile. Then make install. You should now be able to get the wireless to work

modprobe lib80211 (required for security)
modprode wl.ko or insmod wl.ko

You should be able to run iwlist scanning etc... to connect now.

To automate the wireless to boot on load I added the commands above to /etc/rc.local
Reboot and you should be good to go.
