HowTo:Linux: Enable wifi

If you've installed any linux distro and your computer uses pci wifi adapter to connect to the internet you probably have "missing firmware".To install the firmware and enable the wifi adapter:

• download b43-all-fw.tar.gz and extract it(e.g. @ Desktop)
• open a terminal (Applications>Accessories>Terminal OR Ctrl+Alt+T) and run these commands:

           sudo mkdir /lib/firmware/b43 (some distros like Debian require root privileges to run commads that apply to the file system (How To Become Sudoer))

           cd Desktop/b43-all-fw/b43 (the extraction directory)

           sudo cp * /lib/firmware/b43

           sudo chown root:root /lib/firmware/b43/*

           sudo chmod 644 /lib/firmware/b43/*

           sudo rmmod -f b43

           sudo modprobe b43


If you don't get a message about connecting to wifi network try running the same commands replacing b43 with b43legacy.
