I have a Sagemcom F@st 3864V3 OP black modem and the NBN arris router. I have connected the red ethernet cord into the NBN router and the red WAN port on the modem, power is connected to both, the coxial cable is connected also. All of the lights are on and stable on the router and Power, LAN, WAN lights are on and stable on the modem, the WIFI and internet lights are constantly flashing. I can not connect to the internet at all. What am I doing wrong?
Hi there gerarder01,
