Wireless network non existent: Ubuntu 14.04.4

Hey folks,

I have installed ubuntu 14.04.4 to my flash drive and have been ruing it live but there is no option for wireless inteet. My network card is Broadcom BCM43142, i have done reasearch and understand that i require drivers, can someone please help me and provide me with information regarding these drivers... where can i download them?

Are there any commands i can do in the terminal to get these drivers? I currently do not have a access to a wired coection though and rely on wireless.
