NetworkManager doesn't reconnect on its own

Howdie! Anybody know how to make kNetworkManager reconnect automagically when wireless connection is lost? Every time that I lose connection with my router, the kNetworkManager icon stays green although the connection is actually dead. When I click on it, select “Connect to other network” and then select my network’s ESSID it connects alright; but many times I’m not around to do that! Can I set it to do that automatically?
