After the fedora system is installed (, 15), The Broadcom bcm4312 wireless Nic cannot be used. You can enable the wireless Nic using the following methods!

I use the first one ~

1. Use the kernel module b43 + firmware to drive the bcm4312 wireless Nic

After the fedora system is installed, there are b43 modules, but the bcm4312 wireless Nic still cannot drive, because firmware is missing
You can install firmware and reload the b43 module to enable Nic

1. Install necessary tools

     su -
     yum install b43-fwcutter wget

2. Download a Windows Driver

     cd /root/source
     wget http://downloads.openwrt.org/sources/broadcom-wl-4.150.10.5.tar.bz2

3. Decompress the file and extract firmware to the/lib/firmware directory.

     tar -xjvf broadcom-wl-4.150.10.5.tar.bz2
     cd broadcom-wl-4.150.10.5/driver
     b43-fwcutter -w /lib/firmware/ wl_apsta_mimo.o

4. Reload the b43 kernel module

     modprobe -r b43
     modprobe b43

After the above steps, you will find that the wireless network card indicator is on, and you will be able to find the wireless signal soon !!

 

2. Use ndiswrapper to drive the bcm4312 wireless network card

We can also use ndiswrapper to install the driver for Windows.

1. Get a driver for Windows

     ls /root/source
     bcmwl5.inf
     BCMWL5.SYS

2. Use ndiswrapper to install the driver

     ndiswrapper -i bcmwl5.inf

   The system will generate the/etc/ndiswrapper/bcmwl5 directory and generate related files under the directory.

3. You can view the driver installation information:

     ndiswrapper -l
     bcmwl5 : driver installed
     device (14E4:4312) present

4. Configure ndiswrapper

     ndiswrapper -m
     cat /etc/modprobe.d/ndiswrapper
     alias wlan0 ndiswrapper

   Ndiswrapper-mWrite the alias of the wlan0 Nic to the module configuration file. The system starts to automatically load the ndiswrapper kernel module and generates the/etc/modprobe. d/ndiswrapper file.

5. The driver is installed successfully. The ndiswrapper module is loaded.

     modprobe ndiswrapper

After the above steps, you will find that the wireless network card indicator is on, and you will be able to find the wireless signal soon !!
