Hi Tracy thanks for your reply. Yes, I've come acrossed that webpage already. So, I think the router is not getting the ISP's IP address. But now my problem is this. The manual says I shall connect to http://192.168.1.1. When I do this using the laptop with wireless, the page cannot be displayed. And the same with the AP (Access Point) when I try to connect it to the router, it's still getting the error page cannot be displayed.

Any more help?
