If your BCM43228 wireless device is not recognized by Fedora 21/22 :

wget http://download1.rpmfusion.org/nonfree/fedora/rpmfusion-nonfree-release-$(rpm -E %fedora).noarch.rpm rpm -ivh rpmfusion-nonfree-release-22.noarch.rpm dnf clean all dnf install akmod-wl dnf install kernel-devel akmods --force modprobe wl iwconfig systemctl restart NetworkManager

On my HP Probook :

lspci | grep -i Plus >
