A:Answer This system will help, as long as you have electrical outlets to plug in the mesh transceivers along the path you are trying to extend your coverage through. One will get hooked up to the modem, one would (ideally) be somewhere between your man-cave and the main house, and the other one would most likely be in the center of the main house. This is based on not having seen your house, but based on your description, that would be a fairly safe bet as far as the setup, You can always play around with the positioning a bit, once you have them all connected and communicating with each other.
