If no signal, check router config. Use your

By default the password on most Belkin routers is left blank, and the default IP address is 192.168.2.1 Check all you router's wireless settings in case disabled or incorrect. Make sure the laptop's wifi button has been toggled to OFF. Routers do die - esp the lowend ones. New wireless G router = $20 on sale.
