按broadcom官网的readme安装了新的无线网卡驱动：
-----------------------------------
Some of the major linux distros already supply a version of this driver, so
you don't have to compile your own. Most of the distros keep this driver
along with other proprietary or non-GPL drivers in a separate repository.
For further information see the documentation for your specific distro.
Fedora:
------
su -c 'rpm -Uvh
http://download1.rpmfusion.org/free/fedora/rpmfusion-free-release-stable.noarch.rpm
http://download1.rpmfusion.org/nonfree/fedora/rpmfusion-nonfree-release-stable.noarch.rpm'
su -
yum update
yum install kmod-wl
安装应该是成功了，重启之后发现右上角的网络配置不见了，求助该怎么调出来呢
