USB wireless Netgear adapter

Your Broadcom USB wireless usually works with ndiswrapper. Please obtain a temporary internet connection by ethernet, tethered or whatever means possible and open a terminal and do:

sudo apt-get update
sudo apt-get install ndiswrapper-common ndiswrapper-utils-1.9

Now download the files at post #6 here: http://ubuntuforums.org/showthread.php?t=2052594 Drag and drop the file to your desktop so we can find them. Right-click and select 'Extract Here.' Find out if your system is 32- or 64-bit:

arch

Now we install the driver files:

cd ~/Desktop/Broadcom_bcm43xx_USB_32_64bit_v2

If your system is 32-bit (i686), install the 32-bit driver file:

sudo ndiswrapper -i bcmn43xx32.inf

And if it is a 64-bit (x86_64) system:

sudo ndiswrapper -i bcmn43xx64.inf

In either case:

sudo ndiswrapper -ma
sudo depmod -a
sudo modprobe ndiswrapper

Your wireless should now be working.
