Routing packets in a wireless security system. The system includes a network hub that wirelessly sends and receives packets, at least one sensor that wirelessly sends and receives packets to and from the network hub, and a packet router that monitors the packet communications between the network hub and the at least one sensor. The packet router determines when a communication failure occurs, and the packet router is configured to send a first message packet to the network hub if a first type of communication failure occurs and a second message packet to the at least one sensor if a second type of communication failure occurs.
