Since I do not have a computer of my own at the moment (using my family's computer) I do not have the ability to install Ubuntu on a hard disk so I'm planning on just running it from a USB for now. However, I cannot get wireless working on this USB (12.04.1). When I open the "Additional Drivers" window and install the Broadcom wireless driver, I am prompted to restart my computer to activate it, but when I restart, the driver is not activated. Does anyone know how to fix this?
