A network communication system includes a computing device, which includes a processor, a memory device, and a component management module. The component management module is configured to receive a message from customer-premises equipment (CPE). The component management module is also configured to determine from the message that the CPE is operating in a captive portal. The captive portal restricts Internet access to the CPE. The component management module is configured to obtain stored connection credential values corresponding to a subscriber in response to determining that an identification parameter of connection credentials associated with the CPE is valid for the subscriber. The component management module is also configured to provide the stored values to the CPE.
