I installed Ubuntu 12.10 on my Dell E6400, everything is working fine, except my wifi.

The switch on the laptop is on but still Ubuntu does not recognize my wireless adapter.

I ran the lspci | grep Network command and it shows this:

Broadcom Corporation BCM4322 802.11a/b/g/n Wireless

If there is a way to connect to the Internet, you can install the following packages in order to use wireless connections.

Open the Software Center and search&find&install these packages:

b43-fwcutter

firmware-b43-installer

or you can install these packages with a terminal command(Short cut:Ctrl+Alt+T):

sudo apt-get install b43-fwcutter firmware-b43-installer

If your pc haven't a another internet connection, you can download driver packages from the following urls.

http://packages.ubuntu.com/quantal/b43-fwcutter

http://packages.ubuntu.com/quantal/firmware-b43-installer

Please, be careful of packages architecture(The packages architecture you will choose must be same as your Ubuntu architecture.)

After this operation reboot your system and connect a wireless network.
