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 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.
If you don’t want to restart your system then run the following commands in the terminal. Issue the password when you prompted.
sudo modprobe -r b43 ssb wl
sudo modprobe wl
After executing the above commands wait for few seconds, until the network manager scan for the available networks.
Hope this will be helpful for you!!!
