Today, I am going to explain how to install Broadcom wireless NIC cards on CentOS 6.0. First, you should determine which Wlan chip or Wlan controller do you have. Login as root and run the following command:
[root@Centos6 ~]# lspci | grep Broadcom
02:00.0 Network controller: Broadcom Corporation BCM43224 802.11a/b/g/n (rev 01)
As you see, my computer has BCM43224 Wlan chip. So, if your computer has one of the following Wlan chips or Wlan Network Controllers (BCM4311, BCM4312, BCM4313, BCM4321, BCM4322, BCM43224, BCM43225, BCM43227 and BCM43228), your computer will install the wireless after running the instructions below:
- yum install kernel-headers kernel-devel gcc
- Go to this link **Click Here** and download the Broadcom Linux Driver (64 or 32 bits)
- mkdir -p /usr/local/khosro/taraghi-wl
- cd /usr/local/khosro/taraghi-wl
- tar xvfz /home/khosro/Download/hybrid-portsrc_x86_64-v5_100_82_38.tar.gz (You should change the path to the actual path of your tarball that you downloaded)
- make -C /lib/modules/`uname -r`/build/ M=`pwd` ====>Your output should look something like this:
make: Entering directory `/usr/src/kernels/2.6.32-71.29.1.el6.x86_64'

- rmmod bcm43xx
- rmmod b43
- insmod wl.ko ====> Load the driver module
- cp -vi /usr/local/khosro/taraghi-wl/wl.ko /lib/modules/`uname -r`/extra/
- depmod $(uname -r) ===> To create module dependencies
- vim /etc/modprobe.d/blacklist.conf ===>And add the following lines under "# framebuffer drivers" to prevent these modules from being loaded into kernel at boot time:
Save the file. Now, you should see the available wirelesses under Wireless Network if you click on Wired Network icon ,usually, on top right.
