It takes 2-3 hours to install a Viasat. The technician first checks the line of sight to the southern sky to ensure there is a clear path. Once that is established, you and the technician will determine the best location for the dish. During installation, the technician will comply with applicable electrical and FCC rules and regulations. A cable is connected from the dish outside to your modem or gateway device inside. The technician will then install and connect the cable, and set up your home Wi-Fi network so that you are online immediately.
