A building control device comprising a wireless interface and a controller configured to monitor when the wireless interface becomes disconnected from the network. When the wireless interface becomes disconnected from the network, the controller may attempt to reconnect the wireless interface to the network and if successful, return to monitoring for when the wireless interface becomes disconnected from the network. If not successful, the controller may switch the wireless interface into a configuration mode to establish a direct wireless connection with a remote device, receive updated network credentials from the remote device while in the configuration mode, exit the configuration mode, and connect the wireless interface to the network or another network using the updated network credentials.
