the multiple instructional images depicting how an operator manually couples the test hardware in connection with the WAN in a position that isolates the LAN from the WAN for evaluation;
the invoking the test hardware, selecting a test to perform from the test sequence, without intervening user selection of the test from the test sequence, and invoking the test hardware with parameters that control interaction with the WAN; and

Abstract
The present invention relates to testing signals on a coaxial home network that carries a digital video signal. It has direct application to testing Multimedia over Coax Alliance (MoCA) standards-compliant networks and applies to similar networks such as Data Over Cable Service Interface Specification (DOCSIS), Ethernet, and Wi-Fi. An embedded expert system can guide an inexperienced operator through the process of evaluating and resolving problems with a home network with little operator input.
