Bough a new SlingBox. It is connected to a Cable Receiver (near a TV on an upper floor of the house) and directly into a network jack that goes to the main switch and Modem from Verizon coming into the house (in the basement). Attempting to configure the SlingBox from another main computer in the house comes back with "Cannot find SlingBox). This later computer is connected to a wireless router which is itself connected into a main wall jack to the switch connected to the incoming Verizon router (in the basement). If I add a computer between the first wall jack and the Cable Receiver (near the TV) and download the configuration software on that, then will I be able to configure the new SlingBox?
