Tp link w8961nd for cable broadband/ Triple play (Gurgaon)
Hi guys, 
I own a tp link w8961nd that has 4 rj45 Lan ports and rj11 1adsl2+ port. 
My triple play operator says I cannot use my router for cable braodband
After reading from Internet, here nd there I connected rj 45 to one of the Lan ports and other port to my pc and got it to connect to Internet. But wen I try to connect my android phone to wifi of the router, it stops at "obtaining ip address". After again reading here and there, I disabled Dhcp, NAT,.  NOW it keeps on connecting and disconnecting. 
Now I have following queries:
1. Does w8961nd has a Wan port?  If yes, which one?  If no, can I convert Lan port to Wan port? 
2. How can I use wifi with cable broadband? 
3. Can I use w8961nd with cable broadband, or have to buy new router?? 
Thank u in advance
