What does the professional installer do to ensure my Hughesnet Internet Continuity is working?

At the time of installation, your installer will connect your existing LAN/PC to the Automatic Failover Router and then connect the two WAN ports on the router – one to your primary router or modem, and the second to the Hughesnet® Wi-Fi Modem. Lastly, they will unplug your primary modem to verify your Hughesnet Internet Continuity service is operational.
