Configuring Broadcom Corporation Bcm94311mcg Wlan Card

I accidently deleted the wireless device and in the network device manager i don't have it and when i try to add a new card it just gives me wireless card. I tried everything ndiswrapper and getting bcmwl5.inf from the net but nothing worked. I have compaq presario f730us and i wiped my windows vista and now i don't have wireless working. I am a newbie and would appreciate somebody helping me with installing wireless card. i have blacklisted bcm43xxx in etc/modules and everything that was mentioned regarding ndiswrapper.
