Cable Your Modem Router to a Router or Gateway

If you want to cable the modem router to a router or gateway, then you must log in to the

modem router and change its Router Mode setting. Changing this setting prevents certain

network conflicts that can occur when two devices on the same network perform routing

functions such as network address translation (NAT) and DHCP (assigning IP addresses to

devices on the network).
