Most probably you have to install Boradcom drivers to get the correct behavior.
I had the same issue and after few tries I could install the drivers and issue is gone.
Install RPMFusions free and non free versions using these two commands. Change version number (22) according to your version. My installed fedora version is 22.
rpmkeys --import "http://rpmfusion.org/keys?action=AttachFile&do=get&target=RPM-GPG-KEY-rpmfusion-free-fedora-22" "http://rpmfusion.org/keys?action=AttachFile&do=get&target=RPM-GPG-KEY-rpmfusion-nonfree-fedora-22"
dnf install http://download1.rpmfusion.org/free/fedora/rpmfusion-free-release-22.noarch.rpm http://download1.rpmfusion.org/nonfree/fedora/rpmfusion-nonfree-release-22.noarch.rpm
Now your *.rpms are ready. Lets continue to install the drivers. Run below command to install the necessary packages.
dnf install kmod-wl akmod.wl kernel_devel
