Broadcom wireless card

BCM4318 [AirForce One 54g] 802.11g Wireless LAN Controller

If installed “bcm43xx-fwcutter”, blacklist it:
sudo nano /etc/modprobe.d/blacklist
add: blacklist bcm43xx

then,
sudo apt-get install ndiswrapper-common
sudo apt-get install ndiswrapper-utils-1.9

then edit /etc/modules and add ndiswrapper in it

sudo rmmod bcm43xx <–this unloads the bcm43xx driver (now the wireless interface won’t be visible by iwconfig)

Download the windows driver:
ftp://ftp.support.acer-euro.com/notebook/aspire_3020/driver/WLan%20Driver%20Broadcom%20802.11g%203.100.46.0.zip

extract and go into that dir from a shell, then:

sudo ndiswrapper -i bcmwl5.inf
installing bcmwl5 ...
forcing parameter IBSSGMode from 0 to 2
forcing parameter IBSSGMode from 0 to 2

sudo ndiswrapper -l
bcmwl5 : driver installed
device (14E4:4318) present (alternate driver: bcm43xx)

then to load ndiswrapper module:
sudo modprobe ndiswrapper

then iwconfig will list eth1

Turn on the wi-fi button, then,
iwlist eth1 scan
