here is another guy bothering you about Broadcom wireless drivers. I know there are a lot of answered questions dealing with this issue, but none of the solutions seemed to work for me.
I'm running ubuntu 12.04LTS and wireless card is: Broadcom Corporation BCM4313 [14e4:4727].
I already installed the necessary headers, but when I try to activate the driver in "Additional Drivers", I get
"Sorry, installation of this driver failed". Any help would be appreciated.
NOTE: I would appreciate a step by step solution as my linux knowledge is mediocre
