Connect an Ethernet cord on port 1 on the modem and also into your router, which connects your modem and router.
Plug a second Ethernet cord from the router to your device's Ethernet connection. Or connect your device to the router's Wi-Fi.
(Note: Midco provides one Ethernet cord. You'll need another of your own.)
Follow your router's user guide, and contact the manufacturer if you have questions.
Open your web browser, and visit a public website such as Midco.com to test your connection.
You're all set with internet!
