The HG612 is a modem/router in bridge mode.
The HG622, that I and several others on the forums possess, (I don't use mine), is similar to the HG612 but with four Ethernet ports.
The indispensable man or woman passes from the scene, and what happens next is more or less the same thing as was happening before.
