In order to put a network access node such as a wireless router or home gateway in a home network in operation, the node needs to be configured with several parameters requiring technical skills that an ordinary user often does not have. The present invention solves this problem by introducing a system and a method to assist the user to configure the router. The system comprises a web based wizard, an inference engine coupled to said wizard and a knowledge base coupled to said inference engine. The wizard guides the user to provide input which together with stored information retrieved from the knowledge base is processed by the inference engine. The inference engine further generates configuration data that is stored in the wireless router or home gateway. The user can without detailed technical knowledge easily configure the router.
