Fedora 11 does have support for Broadcom wireless drivers, but it didn’t really work out on a friend’s laptop. Finally we got it working and I thought I’ll just note the steps down. Below are the three easy steps you need to take to make it work properly.
Install needed packages
[root@fedora ~]$ yum install broadcom-wl wl-kmod
Once the packages are installed successfully, reboot your laptop.
Use the following command
[root@fedora ~]$ system-config-network
And add a new wireless device wlan0 or whatever you want by filling the required fields properly. If you want the device to be managed by NetworkManager, you can do so while editing the device you just added.
Activate the device. And you are on wifi
