Wifi on Ubuntu Desktop

wireless networks: device not ready (firmware missing).
sudo apt-get update
sudo apt-get install firmware-b43-installer (OR firmware-b43-lpphy-installer) 

This will install the firmware needed to make Broadcom wireless card work.

Also make sure which wireless card is present.
 (Use lspci to find, in my case
Network controller: Broadcom Corporation BCM4312 802.11b/g LP-PHY)
