A method of configuring a network access device having a first network address allocated to a subscriber of services of a first service provider provided by a first service network, with a new network address allocated to a subscriber of services of a second service provider provided by a second service network, wherein the network access device is connected to an access network connected to a plurality of service networks. The method comprises the steps of: sending a request from the network access device to the access network requesting a change to a second service provider; receiving a response from the access network; and initiating a network address change request using a configuration protocol. In this manner, a second network address allocated to the subscriber of services of the second service provider is assigned to the network access device to enable the network access device to communicate data packets to the service network providing the selected service. In one preferred embodiment of the invention, the subscriber is authenticated by a service activation system coupled to the access network prior to initiating the configuration protocol. Accordingly, the request to the access network includes an authentication request for the subscriber. The response received from the access network therefore includes an authentication status for the subscriber from the second service provider. If the subscriber is authenticated, the client initiates the network address change request.
