→Configuring an Ubuntu Wireless Connection
Assuming the wireless network adapter is installed and functioning, Ubuntu will automatically detect it when the system boots. The current status of the network connection is indicated by the NetworkManager signal strength icon located with the system indicators on the right hand side of the top panel. If Ubuntu is unable to access a wireless network, either because none are detected or because the system lacks the authentication credentials to access any detected networks, the icon displayed will consist of a signal strength meter indicating no signal strength. If wireless networks are detected, Ubuntu will also display an on screen display (OSD) notification as illustrated in the following figure:

If only networks are detected for which keys have not previously been configured, it will be necessary to configure access before Ubuntu will be able to establish a connection.
