Running Broadcom BCM4630 on Fedora 19

edit

Hi, I am want to get my new WLAN card running on Fedora. The Hardware is

lspci -vnn -d 14e4:
02:00.0 Network controller [0280]: Broadcom Corporation BCM4360 802.11ac Wireless Network Adapter [14e4:43a0] (rev 03)

I kernel.org says it is not supported, yet. I found somethin on page mattoncloud.org/2013/07/18/fedora-19-on-a-macbook-air-2013-model/ and followed the instruction. Source files from bugzilla are

broadcom-wl-6xx-6.30.223.30-1.fc20.src.rpm
wl-6xx-kmod-6.30.223.30-1.fc20.src.rpm

But when I want to install the new build rpms, via yum install I got following message:

Transaction check error:
  package kernel-3.11.2-201.fc19.x86_64 (which is newer than kernel-3.9.5-301.fc19.x86_64) is already installed
  package kernel-3.11.3-201.fc19.x86_64 (which is newer than kernel-3.9.5-301.fc19.x86_64) is already installed
  package kernel-3.11.4-201.fc19.x86_64 (which is newer than kernel-3.9.5-301.fc19.x86_64) is already installed

I did rebuild the source rpms using rpm --rebuild but nothing changed. Do I really have to downgrade my Kernel? Sincerely Takashi
