Wireless, Ubuntu and Dell

I faced a tough time getting wireless to work on Dell Latitude in Ubuntu. Luckily, Dell provides windows drivers on its support website. So, it must be simple now. Just use ndiswrapper. Right? Wrong. It was not straightforward. I got this useful information from Stacks and Piles.

echo 'blacklist bcm43xx' | sudo tee -a /etc/modprobe.d/blacklist
sudo rmmod bcm43xx
sudo apt-get remove ndiswrapper-utils
sudo apt-get install ndiswrapper-utils
sudo ndiswrapper -i /home/gopal/Desktop/bcmwl5.inf
sudo ndiswrapper -m
sed -e 's/RadioState|1/RadioState|0/' /etc/ndiswrapper/bcmwl5/*.conf
sudo modprobe ndiswrapper
