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

If installed 'bcm43xx-fwcutter', blacklist it:

sudo nano /etc/modprobe.d/blacklist

Add:

blacklist bcm43xx

'ndiswrapper' is a special Linux kernel module that allows you to use Windows network drivers (specifically, NDIS drivers) on a Linux system.

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 enter the directory. Run:

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)

sudo modprobe ndiswrapper

Then iwconfig will list eth1

Turn on the wi-fi button, then:

iwlist eth1 scan
