How to Install Broadcom Wireless card (BCM43XX)
I recently installed Ubuntu 12.04.1 LTS using wubi.exe on my Dell Inspiron 1545 and I'm having some trouble getting my wireless to work properly. When I try to activate my Broadcom STA Wireless Driver, the installation fails. I am brand new to Ubuntu so I don't have much knowledge on how to fix this problem.
