Good question. My new construction home builder installed same gadget high up in living RM. Comcast guy didn't know what it was for when he came out. New home paperwork stated Galaxy, maybe home systems, could come out.... likely they will know. May have to call as wireless router not working well, TV keeps going black, unplug and try again. Comcast no real help, many calls. Second home, same issue, tried different wireless boxes.
