Screenshot - Install Broadcom Wireless Drivers On Ubuntu

The live CD/DVD of UBUNTU has the option for installing and activating the wireless broadcom drivers. But if you haven't installed the drivers during the live environment, how can the drivers be installed after UBUNTU has been installed so that the wireless firmware starts working?
