Unless a public and unsecured wireless network is available (for example at an airport, hotel or library) it will be necessary to configure Ubuntu with appropriate access credentials to gain access to a secured Wi-Fi network. The first step of this process is to identify any networks that are within range of the Ubuntu system. To do so, simply click on the NetworkManager icon in the system indicators section of the panel. This will drop down a menu containing the first five detected networks, the respective signal strength of each network and a number of menu options. A typical Ubuntu NetworkManager menu is illustrated in the following figure:
