after following this command to update wifi drivers:1- Boot into Ubuntu

2- Open a terminal by pressing Ctrl+Alt+T

3- Type in the following (verbatim!)

sudo apt-get update && sudo apt-get upgrade

press Enter, the command will prompt for your password (the one you use to login into Ubuntu), type it and press Enter. Wait for it to finish updating your system. Now type:

sudo apt-get remove bcmwl-kernel-source sudo apt-get install firmware-b43-installer

Wait for the command to finish installing the driver, when done restart your computer. i get a message after the first command when installing has done saying not enough space so it aborts! what do i do to fix this
