Getting Dell BCM4328 Wifi Card Working on Ubuntu 7.10
After trying,searching and crying for more than one month, I finally get it working today in my laptop (Dell Inspiron 6400) 
– I am one of the happiest ever in this world right now 
. here’s how to. All the credit goes to “kayvortex”
Model of my wifi card is “Broadcom BCM4328 802.11a/b/g/n (rev 01)”
Steps
1. Install Ndiswrapper Common and Ndiswrapper Utils (You can do it using synaptic)
2. Download The Driver from ftp://ftp.dell.com/network/R151517.EXE and unzip it somewhere. You will see a folder named DRIVER
3. Execute the following commands
sudo ndiswrapper -i /download_directory/DRIVER/bcmwl5.inf
sudo ndiswrapper -l
sudo modprobe ndiswrapper
4. Then, set ndiswrapper to load on startup:
sudo ndiswrapper -m
gksudo gedit /etc/modules
and add the following module to the list
ndiswrapper
5. Restart (This is a must)
Now you can use Fn+F2 to turn on your wifi )

Wow! What a convenient, practical way of operating a computer! I guess once you quit your job, abandon your children, get a bachelor degree in Linux programming, and break off all social ties with the outside world, Linux really isn’t so bad after all!

First of all, jack sucks. Secondly, thank you so much for the help. It actually worked. I am an Ubuntu n00b, so I followed this guide step by step. It works like a charm.
