WiFi Radar is excellent Python/PyGTK2 application to manage your WiFi profiles. Common usage of this utility lies in scanning for available networks and creating profiles for preferred ones.

At boot time, running WiFi Radar will automatically scan for an available preferred network and connect to it. You can drag and drop your preferred networks to arrange the profile priority.

Damn, sudo aptitude install wifi-radar works in Ubuntu!
