Hi.
It seems that the connection between the computer and modem is not established.
When you were doing Easy Setup Assistant settings, did you plug an Ethernet cable into the modem and computer?

BTW, you can also try it on another windows computer if possible. Or you can try if you can login 192.168.1.1 with default username and password admin/admin. Once you can login the web page of the modem, you can do Quick Start settings to set up Internet connection.

Of course the cable connection between router and computer.
