Apparatus and methods for reporting stream loss in internet gateway devices. One embodiment comprises an internet gateway device for installation at a customer premises. The internet gateway device identifies a request to join an IP multicast stream identified by a group address, and monitors for packets directed to the group address. The internet gateway device detects a stream loss responsive to a failure to receive a packet directed to the group address during a time interval, and reports the stream loss for the group address to a management system.
