Changing the config_stated flag is a workaround; you should try reflashing the interface mote with a new version of IPBaseStation. Basically, the driver sends a packet to the interface mote to set its channel and address, and waits for a reply; the fatal error means you're not getting it. If it still works after you change that flag, you may have an older version installed.
Other then that, the behavior you describe is normal. Basically, the router needs to wait until it hears from a mote to add a routing table entry so it can route to it. If you update to the latest verion in contrib, there's a scheme for generating traffic that will improve convergence time and you can usually ping motes immediate after they boot.
