In my previous post I wrote about how to activate STA wireless driver using Additional Drivers but I had comments saying it doesn’t work. Additional Drivers always search for the proper driver and it will install it, If it doesn’t work for you then you have to install the driver manually.
This Guide is for STA driver only. If you want to install the b43 and b43-legacy follow my other guide on how to install Broadcom b43 driver in Ubuntu 14.04 / 13.10 13.04 / 12.10 / 12.04. If the below driver doesn’t work then try b43 driver.
To Install STA Driver
sudo apt-get install bcmwl-kernel-source
Run the above command to install the driver, type the password for the user when prompted.
Once it finished installing the driver Activate the driver using Additional Drivers, then restart your system. After restarting your system it should work.
Hope this will be helpful for you!!!
