Here are the steps by which I enabled the wireless connection in my friend’s laptop.
Her laptop was “HP DV4 – Entertainment PC-12 cell batteries.”
Q. How to confirm that you have Broadcom Wireless Network Controller.
A. Enter the command as shown below.
asee@asee-hp:~$ lspci -v | grep Broadcom
If you see the Broadcom highlighted in red. Then it confirms that you have Broadcom Wireless.
Then enter the following commands. First off you need to ensure that you have the build essentials package installed so that you can build the b43-fwcutter. Use the following Command to install build-essential.
asee@asee-hp:~$ sudo apt-get install build-essential
When asked enter the password of your computer.
Then we need to install the fwcutter. Once that is installed you can download and build b43-fwcutter. Use the following command shown below :
asee@asee-hp:~$ wget http://bu3sch.de/b43/fwcutter/b43-fwcutter-011.tar.bz2
asee@asee-hp:~$ tar xjf b43-fwcutter-011.tar.bz2
asee@asee-hp:~$ cd b43-fwcutter-011
asee@asee-hp:~$ cd ..
Now we need to download the Broadcom firmware and install it.
asee@asee-hp:~$ wget http://downloads.openwrt.org/sources/broadcom-wl-220.127.116.11.tar.bz2
asee@asee-hp:~$ tar xjf broadcom-wl-18.104.22.168.tar.bz2
asee@asee-hp:~$ cd broadcom-wl-22.214.171.124/kmod
Then use the following command.
asee@asee-hp:~$ ../../b43-fwcutter-011/b43-fwcutter -w /lib/firmware wl_apsta.o
Then we have to activate the wireless device, which is by default deactivated for broadcom drivers.
To activate the device Goto Main Menu (Panel in Ubuntu) >> System >> Administration >> Hardware Drivers.
It will search for Hardware drivers for some moments. Then it will display you with two list of Wireless Card.
Select the Below one with Broadcom STA Drivers
Once it is installed. You can restart your laptop and confirm that wireless is working fine with your card.
Have a nice day.
with best regards,
