wireless setup on Fedora 13

My network adapter is
Broadcom Corporation BCM4312 802.11b/g (rev 01) and I'm trying to setup wireless internet on Fedora 13.
I used the following commands to update, it worked on Fedora 12. But couldn't able to get it going with Fedora 13.
su -c 'yum update'
su -c 'yum install kmod-wl'


Any kind of help is appreciated

Thanks

Did you add the rpmfusion repo after you installed Fedora 13?
