US Patent 9210646 Back-up path for in-home diagnostics and other communications

A local router for a home network pairs with a mobile device via a local network connection. The local router is also connected to a wide area network. The local router receives, from the mobile device and over the local network connection, configuration settings for a backup path for the wide area network. The backup path includes the local network connection and a mobile broadband connection using the mobile device. The local router detects an interruption with the local router's connection to the managed wide area network and forwards, based on the detecting, critical traffic from the home network via the backup path.
