In one embodiment, a repeater node in a shared media network may intercept a shared media transmission from a first node to a second node. Once a shared media transmission is intercepted, the repeater node may determine whether the second node returns an acknowledgement (ACK) to the first node. If the second node does not return an ACK to the first node, the repeater node repeats the shared media transmission to the second node. Also, according to one or more additional embodiments of the disclosure, when receiving an ACK at the repeater node from the second node in response to the repeated shared media transmission, the repeater node may also forward the ACK from the second node to the first node.
