It scans for available networks and create profiles for your preferred networks. It will connect to open hotspots automatically and shows you exactly what it is doing in a cool animated radar screen. You need to browse through a list of access points, find one that you can connect to, manually try to connect to it, confirm the connection and then wait.

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.  WiFi Radar is tested to work with Centrino’s WiFi card IPW2100 but should work just the same for any iwconfig interface.
