Re: HomePlug?
The only thing I can think of is that, in general, routers are not connected directly to the mains electricity. They are connected to a low voltage DC supply via a PSU 'brick' or 'wall wart'. These arrangements are standard and the DC PSU is bought-in or copied-in as a no risk decison, as are reference designs for domestic routers.
