    This has turned out to be a great inexpensive 'Plug-and-Play' cable modem to replace the Time-Warner rental. Purchased the unit and visited Time-Warner Customer Service Office to turn-in the rental and have the replacement's MAC address added to the Time-Warner network. Once home, followed Quick Start guide, connected wireless router and was up and running. The unit seems to have better response than the Time-Warner rental.
