I don't know what kind of broadband you are using, nor what kind of router you are. If the broadband is a fixed IP, you need to set up a Wan port. If not, it doesn't matter.Today's routers have a setup wizard...The router login mode is 192.168.1.1 (the small router of TP needs to set a fixed IP (192.168.1.2-252). Log in to 192.168.1.253 (253 or 254 is forgotten.)
