fedora 20: dell install broadcom wifi

got a relatively new pc that comes with a broadcom wifi and fedoras 18, 19 and 20 can't detect it. i found a lot of help from the net, and here's one that works and is the easiest to follow:

include rpmfusion releases:
# su -c 'rpm -Uvh http://download1.rpmfusion.org/free/fedora/rpmfusion-free-release-stable.noarch.rpm'

# su -c 'rpm -Uvh http://download1.rpmfusion.org/nonfree/fedora/rpmfusion-nonfree-release-stable.noarch.rpm'

update through yum:

# yum update

install wireless driver:

# sudo yum install kmod-wl

restart.

after restart, my fedora 20 took some time before it detected wifi. i also tried turning wifi off and on. i don't know if it had an effect, though. haha
