Do a factory reset, make sure you have a computer on the same subnet, and try to access it again.
I did a factory reset on the antminer and the router and still nothing.
Let me see if I understand. Did you have a modem and wireless before you got router?
I'm checking to see if you have a all in one type modem. And your plugging an additional router to it. With only a cable modem how were you getting internet before? Did you really have a Ethernet from modem to one computer? Or did it have wireless?
