The technology described herein is generally directed towards a gateway device (e.g., a cable modem or telecommunications modem) that is coupled to a base component. The base component couples to an interchangeable lid that is coupled to an electronic device. This forms a sealed housing for outdoor use, e.g., between a provider head end and the subscriber(s). A universal interface provides power or a network connection, or both, to the electronic device. The base component and/or the sealed housing protect the internal components against environmental effects. The base component and/or the sealed housing protect against external RF signals from entering, and internally generated RF signals from exiting.
