I am trying to figure out where I would like them to install, and how much room does the install need.

my living room is closest to the corner of the hosue where the boxes are out on the sidewalk. but the closest corner has a big basket full of blankets, so I don't think I want the modem behind that. the other corner, the cord would run across and be visible to the room.

might install in the bedroom/office that's more centralized in the hosue.
