A modem includes a dynamic host configuration protocol (DHCP) module, a point-to-point protocol over Ethernet (PPPoE) module, and a network monitor module. The DHCP module automatically establishes a DHCP connection over a communication network, and generates a first notification signal after the DHCP connection is established. The PPPoE module automatically establishes a PPPoE connection over the communication network and automatically configures parameters of an Internet access service over the communication network and generates a second notification signal after the PPPoE connection is established. The network monitor module determines current network properties of the communication network upon receipt of the first notification signal and/or the second notification signal, and selectively configures parameters of the Internet access service and a voice over Internet protocol (VoIP) service.
