Or maybe simple shell script pinging your default gateway in regular 
intervals could bring the connection down via dbus-send if no packet got 
through. This should be more failproof than guessing from signal 
strenght. I don't remember correct message but you can monitor dbus 
messages via dbus-monitor and bring down the connection by hand to see 
it. At least I hope there is such method call for closing connections :-)
