ZTE Modem config with Wireless router

I have the blue ZTE ZXDSL 831 modem from PTCL, and i got a d-link wireless router. I followed the router settings, hooked up correctly, the status light on the router just keeps blinking. And when its set up properly, i cant access the router or the modem config page.

I'm quite sure i need to change the modem config before i hook it up to the router. Anyone know what i need to change?
