A device in a home security system may detect a disconnect from a network and enter automatic setup mode based on trigger conditions. The trigger conditions are used to determine that the disconnect is based on changes to network configuration settings. The trigger conditions may include failing multiple attempts to access the network using a saved network password, or determining that an access point signal with a saved service set identifier has not been detected for at least a threshold time. Based on one or more trigger conditions being met, the device may enter automatic setup mode to receive updated configuration settings from a client device.
