I just installed Kali Linux on Dell Inspiron 1545, and am unable to get wireless connection.

I attempted the following

Code:
root@kali:~# lspci -knn | grep Net -A2
0c:00.0 Network controller [0280]: Broadcom Corporation BCM4312 802.11b/g LP-PHY [14e4:4315] (rev 01)
    Subsystem: Dell Wireless 1397 WLAN Mini-Card [1028:000c]

# apt-get install firmware-iwlwifi
# modprobe -r iwlwifi; modprobe iwlwifi
I even tried commands I used when I installed Ubuntu on the same laptop

Code:
sudo apt-get install bcmwl-kernel-source
sudo modprobe -r b43 bcma
sudo modprobe wl
I also ran

Code:
sudo apt-get install kali-linux-wireless
but I still cannot detect and connect to my home wi-fi.

Thanks!
