Have you installed the firmware with b43-fwcutter yet? Or are you using the windows drivers with ndiswrapper?

Open an xterminal and do the following:


su -
yum install b43-fwcutter NetworkManager NetworkManager-glib NetworkManager-gnome
system-config-network


In the Network Configuration GUI that pops up click on the Devices tab and on the Hardware tab. If a line containing "wlan0" does not appear in either tab reboot your machine and once logged back in open an xterminal, become root and re-issue the command "system-config-network". Check the tabs again. You should see in the Devices tab a line containing "wlan0". If not don't worry we are now going to force the bugger with a sledge hammer.

Click on the "Devices" tab then select "New" from the menu. Follow the on-screen dialog to create a new device.

After it's been created click on "Edit" from the menu and do:
--In the "General" tab make sure the following are enabled:
Controlled by NetworkManager
Activate device when computer starts
Allow users to enable and disable the device
Enable IPv6 configuration for this interface
Automatically obtain IP address settings with: "dhcp"
Automatically obtain DNS information from provider
--In the "Hardware device" tab make sure:
Hardware is set to "wlan0 (b43)"
Device alias number is unchecked
Bind to MAC address is checked
--In the "Wireless Settings" tab make sure:
Mode is set to "auto"
Network name (SSID) is set to "auto"
Channel is set to "1"
Transmit rate is set to "Auto"

Now save your changes by choosing File-- Save from the GUI menu and then exit the GUI.

Open an xterminal and issue the following commands:


cd /home/[user name]/[download directory]
wget -c http://downloads.openwrt.org/sources/broadcom-wl-4.150.10.5.tar.bz2
tar -xfvj broadcom-wl-4.150.10.5.tar.bz2
cd broadcom-wl-4.150.10.5/driver
su
b43-fwcutter -w /lib/firmware wl_apsta_mimo.o
exit
exit


now reboot your computer for setting to take effect.

You may have a spot of bother during the boot process IF you also have a wired NIC in the computer. Don't worry, eventually you will boot fully. When you do go back into an xterminal, become root and use the system-config-network command again. In the Devices tab click on your wired NIC to highlight it and click on the Edit button in the menu. Under the General tab uncheck the box next to "Activate device when computer starts". Next time you boot up you shouldn't have any trouble waiting for it to find a connection before moving on to the next item to start in your boot process.

This solution worked on my laptop from Acer having the BCM94311MCG wlan mini-PCI (rev 01) NIC with a fully updated F9 installation (32bit). However, If you are still having difficulties then I suggest visiting:

http://linuxwireless.org/
http://openwrt.org/
http://www.linuxhardware.org/

for possibly updated information concerning your wireless NIC. Further cruising of the Fedora Forum is also highly advised.
